Description
Die vorliegende Erfindung betrifft die Verwendung eines Lösungsmittels mit bestimmten Eigenschaften und Merkmalen in einem Verfahren zur chemischen Reinigung von Textil-, Leder- oder Pelzwaren, bei dem man die zu reinigende Ware mit einem Reinigungsmittel in Kontakt bringt, wobei das Reinigungsmittel das Lösungsmittel umfaßt. Darüber hinaus betrifft die vorliegende Erfindung auch die Herstellung eines Reinigungsmittels zur chemischen Reinigung von Textilien, Leder- und Pelzwaren, wobei das Reinigungsmittel einen Anteil des Lösungsmittels mit den bestimmten Eigenschaften und Merkmalen aufweist.The present invention relates to the use of a solvent having certain properties and features in a process for the dry cleaning of textile, leather or fur products, in which bringing the product to be cleaned with a cleaning agent in contact, wherein the cleaning agent comprises the solvent. Moreover, the present invention also relates to the production of a cleaning agent for the dry cleaning of textiles, leather and fur products, wherein the cleaning agent has a proportion of the solvent with the specific properties and characteristics.
Die professionelle Reinigung von Textil-, Leder- oder Pelzwaren ist eine spezielle Dienstleistung der modernen Gesellschaft mit wirtschaftlich sehr großer Bedeutung. Insbesondere formelle und festliche Bekleidung ist üblicherweise aus hochwertigen Materialien, wie z.B. Cashmere, Wolle oder Seide, gefertigt oder besteht wenigstens zum Teil aus Leder oder Pelz. Diese Materialien können in Wasser Quellen und neigen bei der traditionellen Nassreinigung teilweise auch zur Verfilzung. Zudem haben manche Färbungen von an sich für die Nassreinigung geeigneten Materialien geringe Nassechtheiten.The professional cleaning of textile, leather or fur products is a special service of modern society with economically very great importance. In particular, formal and festive clothing is usually made of high quality materials, such as e.g. Cashmere, wool or silk, made or at least partly made of leather or fur. These materials can be found in water and tend to be matted during traditional wet cleaning. In addition, some dyeings of materials suitable for wet cleaning have low wet fastness properties.
Die Pflege solcher Waren muss daher in aller Regel in der gewerblichen Textilreinigung unter Verwendung von geeigneten Lösungsmitteln durchgeführt werden. Der generelle Vorteil einer Lösungsmittelbehandlung von Textilien liegt darin, dass Naturfasern in organischen Lösungsmitteln nur geringes Quellungsverhalten aufweisen und damit die Gefahr der Verfilzung sehr gering ist.The care of such goods must therefore be carried out as a rule in the commercial textile cleaning using suitable solvents. The general advantage of a solvent treatment of textiles is that natural fibers in organic solvents have only low swelling behavior and thus the risk of entanglement is very low.
Die Eignung apolarer Lösungsmittel, wie z.B. aromatische Kohlenwasserstoffe, Leichtbenzine, Stoddard Solvent und White Spirit, zur Reinigung von Textilien ist seit dem frühen 19. Jahrhundert bekannt. Später kamen dann auch Halogenkohlenwasserstoffe, wie z.B. Chlorkohlenwasserstoffe (CKW) und Fluorchlorkohlenwasserstoffe (FCKW) zum Einsatz. Die v.a. in den 70er und 80er Jahren weitverbreiteten FCKW wurden aufgrund des Montrealer Abkommens zum Schutz der Ozonschicht 1987 jedoch verboten.The suitability of apolar solvents, e.g. aromatic hydrocarbons, light gasoline, Stoddard Solvent and White Spirit, for cleaning textiles has been known since the early 19th century. Later, halohydrocarbons, e.g. Chlorinated hydrocarbons (CHC) and chlorofluorocarbons (CFC) are used. The v. A. However, CFCs that were widely used in the 1970s and 1980s were banned under the 1987 Montreal Convention for the protection of the ozone layer.
Inzwischen haben sich wieder halogenfreie Lösungsmittel, wie z.B. Isoparaffine (KWL) und Cyclosiloxan D5 (Decamethylcyclopentasiloxan) in der Textilreinigung etabliert. Diese Lösungsmittel müssen bei deren Verwendung in Anlagen, bei denen die Aufbereitung des Lösungsmittels überIn the meantime, halogen-free solvents such as isoparaffins (KWL) and cyclosiloxane D5 (decamethylcyclopentasiloxane) have again become established in textile cleaning. These solvents have to be used in installations where the preparation of the solvent is over
Destillation erfolgt, bedingt durch ihren hohen Siedebereich (KWL: 185 - 210 °C) bzw. Siedepunkt (Cyclosiloxan D5: Sdp.: 211°C) unter reduziertem Druck destilliert werden, was zu entsprechend erhöhten Energiekosten führt. Um diese einzusparen gibt es inzwischen Anlagen, die ohne Destillation oder mit reduzierter Destillationsrate arbeiten und zur Lösungsmittelregeneration stattdessen Filterpulver bzw. Kartuschenfilter einsetzen.Due to their high boiling range (KWL: 185-210 ° C.) or boiling point (cyclosiloxane D5: b.p .: 211 ° C.), distillation takes place under reduced pressure, which leads to correspondingly increased energy costs. To save this, there are now systems that work without distillation or with reduced distillation rate and instead use filter powder or cartridge filters for solvent regeneration.
Eine der neuesten Entwicklungen auf dem Gebiet ist die Verwendung von flüssigem Kohlendioxid zur Reinigung von Textilien. Die für die Verwendung von flüssigem Kohlendioxid notwendigen Hochdruckanlagen sind im Verhältnis zu konventionellen Reinigungsmaschinen jedoch deutlich teurer, was die Verbreitung der neuen Technik bisher behindert hat.One of the latest developments in the field is the use of liquid carbon dioxide to clean textiles. However, the high-pressure systems required for the use of liquid carbon dioxide are considerably more expensive in comparison to conventional cleaning machines, which hitherto hindered the spread of the new technology.
Das weltweit am häufigsten in der gewerblichen Textilreinigung verwendete Lösungsmittel ist Perchlorethylen (= Tetrachlorethen, Per). Perchlorethylen ist unbrennbar, hat eine Siedetemperatur von 121 °C und kann in den Reinigungsmaschinen bei Normaldruck destilliert werden. Perchlorethylen ist ein Lösungsmittel mit ausgezeichneter Lösekraft gegen verschiedenste Verschmutzungen und ein Großteil der Obergarderobe ist nach internationalem Pflegekennzeichen der Textilien in Perchlorethylen reinigungsfähig.The solvent most commonly used in commercial textile cleaning worldwide is perchlorethylene (= tetrachloroethene, per). Perchlorethylene is incombustible, has a boiling point of 121 ° C and can be distilled in the cleaning machines at atmospheric pressure. Perchlorethylene is a solvent with excellent dissolving power against a wide variety of soiling and a large part of the upper coat rack can be cleaned according to the international care label of textiles in perchlorethylene.
Nachteilig bei der Anwendung von Perchlorethylen ist die Gefahr der Grundwasser- und Bodenkontamination. Nach Gefahrstoffverordnung ist Perchlorethylen als gesundheitsschädlich mit Risikosatz R40 eingestuft und steht damit im Verdacht Krebs auszulösen. In einigen EU-Mitgliedstaaten dürfen Reinigungsmaschinen mit Perchlorethylen daher nicht in Supermärkten mit Lebensmittelverkauf betrieben werden. Durch die Gefahr, dass Perchlorethylendämpfe das Mauerwerk durchdringen, müssen außerdem Vorkehrungen zur Emissionsverminderung durchgeführt werden. Manche Bundesstaaten der USA, wie z.B. Kalifornien, haben Perchlorethylen als Lösungsmittel in der Textilreinigung ab dem Jahr 2020 verboten.A disadvantage of the use of perchlorethylene is the risk of groundwater and soil contamination. According to the Hazardous Substances Ordinance, perchlorethylene is classified as hazardous to health with risk phrase R40 and is therefore suspected of causing cancer. Therefore, in some EU Member States, perchlorethylene cleaning machines should not be operated in supermarkets selling food. Due to the danger that perchlorethylene vapors penetrate the masonry, provision must also be made for emission reduction. Some states of the USA, such as California, has banned perchlorethylene as a solvent in textile cleaning from 2020.
Die gesetzlichen Auflagen im Hinblick auf Anwendung, Lagerung und Transport des am häufigsten in der gewerblichen Textilreinigung verwendeten Perchlorethylens führen zu einem Bedarf nach geeigneten Alternativlösungsmitteln in der gewerblichen Textilpflege.The legal requirements regarding the use, storage and transport of the most commonly used in commercial textile cleaning perchlorethylene lead to a need for suitable alternative solvents in commercial textile care.
Halogenierte Lösungsmittel haben die bereits genannten Nachteile für Mensch und Umwelt. Die als weitere Alternativen in Betracht kommenden Lösungsmittel wie KWL, Cyclosiloxan oder flüssiges Kohendioxid haben im Vergleich zu Perchlorethylen zwar eine günstigere Gefahreinstufung, weisen in der Praxis insbesondere bei stark verschmutzen Textilien und vor allem bei Verschmutzungen durch Pigmente und Salze jedoch spezifische Nachteile in der Reinigungsleistung auf, die nur durch verstärkte Anstrengungen in der Detachur zu kompensieren sind.Halogenated solvents have the already mentioned disadvantages for humans and the environment. Although solvents such as HCL, cyclosiloxane or liquid carbon dioxide, which are considered as further alternatives, have a more favorable hazard classification compared to perchlorethylene, they have specific disadvantages in terms of cleaning performance in practice, especially in the case of heavily soiled textiles and, above all, soiling by pigments and salts , which can only be compensated by increased efforts in the Detachur.
Die Aufgabe der vorliegenden Erfindung ist es, ein Lösungsmittel bereitzustellen, welches bezüglich seiner Reinigungseigenschaften im Vergleich zu Perchlorethylen oder den anderen bei der chemischen Reinigung von Textil-, Leder- oder Pelzwaren üblicherweise verwendeten Lösungsmitteln im wesentlichen gleichwertig oder sogar besser ist. Gleichzeitig soll dieses Lösungsmittel im Vergleich zu Perchlorethylen oder den anderen bei der chemischen Reinigung von Textil-, Leder- oder Pelzwaren üblicherweise verwendeten Lösungsmitteln ökologisch und toxikologisch günstigere Eigenschaften aufweisen, so dass die Verwendung, die Lagerung und der Transport dieses Lösungsmittels oder eines dieses Lösungsmittel enthaltenden flüssigen Reinigungsmittels sicherer oder mit weniger Kosten- und/oder Energieaufwand möglich ist.The object of the present invention is to provide a solvent which is substantially equivalent or even better in terms of its cleaning properties compared to perchlorethylene or the other solvents commonly used in the dry-cleaning of textile, leather or fur products. At the same time this solvent should have ecologically and toxicologically more favorable properties compared to perchlorethylene or the other commonly used in the dry cleaning of textile, leather or fur products solvents, so that the use, storage and transport of this solvent or a solvent containing this liquid detergent safer or with less cost and / or energy consumption is possible.
Diese Aufgabe wird erfindungsgemäß gelöst durch die Verwendung eines Lösungsmittel mit der allgemeinen Formel (I):
- x = 1 ist,
- R1 und R3 H sind und
- R2 und R4 unabhängig voneinander unter einem unsubstituierten oder substituierten n-Butyl-, iso-Butyl-, sekundären Butyl-, tertiären Butyl-, n-Pentyl-, iso-Pentyl-, Neopentyl-, Cyclopentyl-, n-Hexyl-, iso-Hexyl-, Cyclohexyl-, Octyl-, iso-Octyl-, 2-Ethylhexylrest ausgewählt sind,
- x = 1,
- R 1 and R 3 are H and
- R 2 and R 4 are independently selected from unsubstituted or substituted n-butyl, iso-butyl, secondary butyl, tertiary butyl, n-pentyl, iso-pentyl, neo-pentyl, cyclopentyl, n-hexyl , isohexyl, cyclohexyl, octyl, iso-octyl, 2-ethylhexyl are selected,
Lösungsmittel der Formel (I) sind formal Diether und sind durch die üblichen zur Etherfunktion führenden Synthesewege zugänglich, z. B. durch Wiliamson-Ethersynthese, Reaktion von Oxiranen, Oxetanen, Tetrahydrofuranen und höheren Analogen mit Alkoholen. Beispielsweise können Verbindungen mit Formel (I), bei denen x = 1 ist, durch Umsetzung einer Carbonylverbindung wie z. B. eines Aldehyds oder Ketons mit 2 Mol Alkohol pro Carbonylgruppe entstehen. Üblicherweise wird diese reversible Reaktion sauer katalysiert. Zur Verschiebung des Gleichgewichtes wird der Alkohol meist im Überschuss eingesetzt und das entstehende Wasser aus dem Reaktionsgemisch entfernt. Um den für die Verwendung als Lösungsmittel in der Chemischreinigung erforderlichen Reinheitsgrad zu erhalten, ist es zweckmäßig, in den Fällen, in denen eine saure Katalyse durchgeführt wurde, die katalysierende Säure entweder zu entfernen oder zu neutralisieren, um die Zersetzung des Lösungsmittels bei der Verwendung zu verhindern.Solvents of the formula (I) are formally diethers and are accessible by the usual synthesis routes leading to the ether function, eg. By Wiliamson ether synthesis, reaction of oxiranes, oxetanes, tetrahydrofurans, and higher analogs with alcohols. For example, compounds of formula (I) wherein x = 1 can be prepared by reacting a carbonyl compound, such as, e.g. As an aldehyde or ketone with 2 moles of alcohol per carbonyl group. Usually, this reversible reaction is catalysed acid. To shift the equilibrium, the alcohol is usually used in excess and the resulting water is removed from the reaction mixture. In order to obtain the degree of purity required for use as a solvent in dry cleaning, it is desirable to either remove or neutralize the catalyzing acid in cases where acidic catalysis has been carried out in order to permit decomposition of the solvent in use prevent.
Es hat sich überraschenderweise herausgestellt, dass das Reinigungsvermögen von Verbindungen der Formel (I) im Vergleich zu Perchlorethylen und den anderen bei der chemischenIt has surprisingly been found that the detergency of compounds of formula (I) compared to perchlorethylene and the other in the chemical
Reinigung von Textil-, Leder- und Pelzwaren herkömmlich verwendeten Lösungsmitteln wenigstens gleichwertig und zum Teil sogar besser ist. Da viele Verbindungen der Formel (I) keine den Erfindern bekannte Einstufung nach Gefahrstoffverordnung haben, sind diese den meisten anderen bei der chemischen Reinigung von Textil-, Leder- und Pelzwaren herkömmlich verwendeten Lösungsmitteln außerdem im Hinblick auf ihre ökologischen und toxikologischen Eigenschaften überlegen. Insbesondere sind die ökologischen und toxikologischen Eigenschaften vieler Verbindungen der Formel (I) besser als die ökologischen und toxikologischen Eigenschaften von Perchlorethylen.Cleaning of textile, leather and fur products conventionally used solvents at least equivalent and sometimes even better. Since many compounds of the formula (I) have no classification according to the Ordinance on Hazardous Substances known to the inventors, they are also superior to most of the solvents conventionally used in the dry-cleaning of textile, leather and fur products in view of their ecological and toxicological properties. In particular, the ecological and toxicological properties of many compounds of formula (I) are better than the environmental and toxicological properties of perchlorethylene.
Darüber hinaus erfüllen die Verbindungen der Formel (I) auch die typischen Anforderungen für ein bei der Reinigung von Textil-, Leder- und Pelzwaren zu verwendendes Lösungsmittel.In addition, the compounds of the formula (I) also meet the typical requirements for a solvent to be used in the cleaning of textile, leather and fur products.
Insbesondere weist das Lösungsmittel gemäß Formel (I) gute Löseeigenschaften für ölige und fettige Verschmutzungen, wie z.B. Öle, Fette, Wachse, Fettsäuren, auf. Es löst darüber hinaus auch Pigmente und Salze gut von der Textilfaser und stabilisiert die abgelösten Pigmente und Salze in der Lösungsmittelflotte.In particular, the solvent according to formula (I) has good dissolving properties for oily and greasy soils, e.g. Oils, fats, waxes, fatty acids, on. It also dissolves pigments and salts well from the textile fiber and stabilizes the detached pigments and salts in the solvent liquor.
Viele Ausführungsformen des Lösungsmittels gemäß Formel (I) sind einfach und ohne thermische Zersetzung des Lösungsmittels destillierbar. Bei bestimmten Ausführungsformen ist das Lösungsmittel gemäß Formel (I) mit Wasser nicht mischbar und ist daher, falls erforderlich, recht einfach (z.B. in einem Wasserabscheider) von einer Wasserphase abtrennbar.Many embodiments of the solvent according to formula (I) are easily distillable without thermal decomposition of the solvent. In certain embodiments, the solvent according to formula (I) is immiscible with water and therefore, if necessary, is quite easily (e.g., in a water separator) separable from a water phase.
Außerdem weist das Lösungsmittel gemäß Formel (I) ein günstiges Trocknungsverhalten auf und ist im wesentlichen geruchsneutral. Darüber hinaus führt das Lösungsmittel gemäß Formel (I) nicht zu Farbverlusten und beeinflußt die Dimensionsstabilität von Textilien nicht negativ. Von Bedeutung ist auch, dass in der Textilkonfektion eingesetzte Kleber von dem Lösungsmittel gemäß Formel (I) nicht angelöst werden.In addition, the solvent according to formula (I) has a favorable drying behavior and is substantially odorless. In addition, the solvent according to formula (I) does not lead to color losses and does not adversely affect the dimensional stability of textiles. It is also important that adhesives used in textile finishing are not dissolved by the solvent according to formula (I).
Nach alledem ist die Verwendung des Lösungsmittels gemäß Formel (I) in einem Verfahren zur chemischen Reinigung von Textil-, Leder- oder Pelzwaren, bei dem man die zu reinigende Ware mit diesem Lösungsmittel in Kontakt bringt, äußerst vorteilhaft. Bei der Verwendung des Lösungsmittel gemäß Formel (I) in einem Verfahren zur chemischen Reinigung von Textil-, Leder- oder Pelzwaren kann dieses Lösungsmittel daher Perchlorethylen, Kohlenwasserstoffe (KWL), Cyclosiloxan D5 oder andere zur chemischen Reinigung verwendete Lösungsmittel vollständig oder zumindest teilweise ersetzen.After all, the use of the solvent according to formula (I) in a process for the dry cleaning of textile, leather or fur products, in which bringing the product to be cleaned with this solvent in contact, extremely advantageous. Thus, when using the solvent of formula (I) in a process of dry-cleaning textile, leather or fur products, this solvent can completely or at least partially replace perchlorethylene, hydrocarbons (HCL), cyclosiloxane D5 or other solvents used for chemical cleaning.
Zu den zu reinigenden Waren (Reinigungsgut) im Sinne der vorliegenden Erfindung zählen unter anderem Textil-, Leder- und Pelzwaren jeglicher Art, wie z.B. Kleidungsstücke mit Textil-, Leder- und/oder Pelzanteil, Berufs- und Schutzbekleidung jeglicher Art mit Textil- und/oder Lederanteil, aber auch Vorhänge, Teppiche und Dekorationsmaterialien mit Textil-, Leder- und/oder Pelzanteil.For the purposes of the present invention, the goods to be cleaned (items to be cleaned) include, inter alia, textile, leather and fur articles of any kind, such as items of clothing Textile, leather and / or fur, professional and protective clothing of any kind with textile and / or leather content, but also curtains, carpets and decorative materials with textile, leather and / or fur.
Der Begriff chemische Reinigung ist im Zusammenhang mit der vorliegenden Erfindung breit zu verstehen und umfaßt auch die Vorbehandlung (Detachur) von Textilien, Leder- und Pelzwaren im Zusammenhang mit der chemischen Reinigung dieser Waren.The term dry cleaning is to be understood in the context of the present invention broadly and includes also the pretreatment (detachment) of textiles, leather and fur products in connection with the dry cleaning of these goods.
Vorzugweise erfolgt das Inkontaktbringen der zu reinigenden Ware mit dem Reinigungsmittel in einer Chemischreinigungsmaschine. Bei einer Ausführungsform der Erfindung erfolgt die Reinigung der Textil-, Leder- oder Pelzwaren daher unter Verwendung des Lösungsmittels gemäß Formel (I) maschinell in Reinigungsmaschinen. Solche Reinigungsmaschinen sind üblicherweise geschlossene Systeme, in denen das Lösungsmittel entweder durch Destillation, Absorption oder durch Kombination beider Aufbereitungsverfahren rezykliert wird.Preferably, the contacting of the goods to be cleaned with the cleaning agent in a dry cleaning machine. In one embodiment of the invention, the cleaning of textile, leather or fur products is therefore carried out using the solvent according to formula (I) by machine in cleaning machines. Such cleaning machines are usually closed systems in which the solvent is recycled either by distillation, absorption or by a combination of both treatment processes.
Bei Transferanlagen, die v.a. in den 50er Jahren bei der chemischen Reinigung mit Perchlorethylen oder White Spirit zum Einsatz kamen, wurden Reinigungsprozess und Destillation üblicherweise in der Reinigungsmaschine und die Trocknung der Textilien in einem separaten Trockner (oft mit Lösungsmittelrückgewinnung) durchgeführt.For transfer systems, the v.a. In the 50's when used in the chemical cleaning with perchlorethylene or white spirit, cleaning process and distillation were usually performed in the cleaning machine and the drying of the textiles in a separate dryer (often with solvent recovery).
Moderne Maschinen arbeiten mit der "Dry to Dry"-Technik, bei der das Reinigungsgut trocken beladen und nach Ablauf des Prozesses auch wieder getrocknet entladen wird. Das an einem Lösungsmittelkühler kondensierte Lösungsmittel-Wassergemisch kann bei diesem Verfahren in einem Wasserabscheider wieder in organische Phase und Wasserphase getrennt werden. Anschließend kann das Lösungsmittel dann über einen Überlauf des Wasserabscheiders in den Reintank laufen, während das Wasser als kontaminiertes Kontaktwasser dem System entnommen werden und zur Einhaltung der Einleitergrenzwerte entsprechend aufgereinigt werden kann.Modern machines work with the "Dry to Dry" technology, in which the material to be cleaned is loaded dry and, after the end of the process, is discharged again in a dry state. The solvent-water mixture condensed on a solvent cooler can be separated again into organic phase and water phase in a water separator in this process. Subsequently, the solvent can then run over an overflow of the water separator in the clean tank, while the water can be removed as contaminated water contact the system and can be cleaned to comply with the Einleitgrenzwerte accordingly.
Die Reinigungsprozesse können sowohl einbadig als auch zweibadig (Vor- und Hauptreinigungsbad) oder, wie beispielsweise im Falle von Arbeitsbekleidung, auch mehrbadig durchgeführt werden. Bei einem zwei- oder mehrbadigen Verfahren kann das erfindungsgemäß verwendete Lösungsmittel mit der Formel (I) im ersten oder in einem auf das erste Bad folgenden Bad mit dem Reinigungsgut in Kontakt gebracht werden. In dem anderen Bad oder den anderen Bädern kann/können ein oder mehrere andere Lösungsmittel für die chemische Reinigung von Textil-, Leder- oder Pelzwaren enthalten sein. Alternativ kann das erfindungsgemäß verwendete Lösungsmittel mit der Formel (I) auch in mehr als einem oder in allen Bädern mit dem Reinigungsgut in Kontakt gebracht werden.The cleaning processes can be both one-bath and zweibadig (pre- and main cleaning bath) or, as for example in the case of work wear, also carried mehrbadig. In a two- or mehrbadigen process, the solvent used in the invention can be brought into contact with the cleaning material in the first or in a subsequent to the first bath with the formula (I). The other bath or baths may contain one or more other solvents for the dry cleaning of textile, leather or fur products. Alternatively, the solvent used according to the invention can be brought into contact with the cleaning material in more than one or in all baths with the formula (I).
Bei einem alternativen Reinigungsprozess gemäß der vorliegenden Erfindung wird das Lösungsmittel der Formel (I) in speziellen Reinigungsanlagen einmal oder mehrmals auf das Reinigungsgut aufgesprüht. Dieses Verfahren kann zusätzlich auch Verfahrensstufen umfassen, bei denen das Reinigungsgut in ein oder mehrere Reinigungsbäder mit dem Lösungsmittel der Formel (I), wie sie in dem vorangehenden Absatz beschrieben sind, eingetaucht wird. Das Verfahren kann auch Verfahrensstufen umfassen, bei denen das Reinigungsgut auch mit einem anderen Lösungsmittel für die chemische Reinigung von Textil-, Leder- oder Pelzwaren in Kontakt gebracht wird, sei es durch Besprühen oder Eintauchen in ein Reinigungsbad.In an alternative purification process according to the present invention, the solvent of the formula (I) is sprayed on the items to be cleaned once or several times in special cleaning systems. This process may additionally comprise process steps in which the cleaning product is immersed in one or more cleaning baths with the solvent of the formula (I) as described in the preceding paragraph. The method may also include process steps in which the items to be cleaned are also brought into contact with another solvent for the dry cleaning of textile, leather or fur products, whether by spraying or immersion in a cleaning bath.
Bei einer Ausführungsform des erfindungsgemäßen Verfahrens wird das Reinigungsgut in der gleichen Maschine, in der es auch eingetaucht oder besprüht wurde, getrocknet ("Dry to Dry"-Technik), so dass das Reinigungsgut trocken beladen und nach Ablauf des Prozesses auch wieder getrocknet entladen wird.In one embodiment of the method according to the invention, the cleaning material in the same machine in which it was also dipped or spray dried ("dry to dry" technique), so that the cleaning material is loaded dry and unloaded after the process is dried again ,

Bei bestimmten Ausführungsformen des erfindungsgemäßen Reinigungsverfahrens erfolgt die Aufbereitung des Reinigungsmittels bzw. des Lösungsmittels durch Destillation. Bei noch spezielleren Ausführungsformen erfolgt diese Destillation unter reduziertem Druck (Vakuumsdestillation). Manche Ausführungsformen des erfindungsgemäß verwendeten Lösungsmittels mit der Formel (I) haben bei 1013 mbar einen Siedepunkt < 215 °C.

Bei bestimmten Ausführungsformen der Erfindung weist das Reinigungsmittel auch einen Anteil eines Reinigungsverstärkers (bzw. Reinigungsaktivators) auf. Bei anderen Ausführungsformen wird während des Verfahrens zu dem Reinigungsmittel ein Reinigungsverstärker zudosiert. Bei noch anderen Ausführungsformen wird die zu reinigende Ware während des Verfahrens in anderer Weise separat mit einem Reinigungsverstärker in Kontakt gebracht.In certain embodiments of the invention, the cleaning agent also comprises a portion of a cleaning amplifier (or cleaning activator). In other embodiments, a cleaning booster is added to the cleaning agent during the process. In yet other embodiments, the article to be cleaned is otherwise contacted separately with a cleaning booster during the process.
Reinigungsverstärker (bzw. Reinigungsaktivatoren) sind Tensidformulierungen zur Verbesserung des Reinigungseffektes. Zu den weiteren Aufgaben eines Reinigungsverstärkers zählen das Emulgieren von Wasser, um die Nassschmutzentfernung zu verbessern, und das Dispergieren von Pigmenten und Salzen im Lösungsmittel, um deren Ablösung vom Textilgewebe zu verbessern und um deren Redeposition zu verhindern. Manche Reinigungsverstärker stabilisieren abgelöste Feinpigmente in der Reinigungsflotte und schützen damit das Reinigungsgut vor Vergrauung. Reinigungsverstärker können ferner Korrosionsschutzadditive oder nichtionische bzw. kationische Tenside zur Griffverbesserung mit "easy finish"-Eigenschaften oder Appreturen sein. Manche Reinigungsverstärker sorgen für hygienische Effekte in der Textilpflege, andere reduzieren oder vermeiden die statische Aufladung des Reinigungsgutes während der Trocknungsphase, wodurch z.B. bei Wolle die Flusenbildung deutlich reduziert wird.Cleaning enhancers (or cleaning activators) are surfactant formulations to improve the cleaning effect. Other tasks of a cleaning enhancer include emulsifying water to improve wet soil removal, and dispersing pigments and salts in the solvent to improve their release from the fabric and prevent their redeposition. Some cleaning agents stabilize dissolved fine pigments in the cleaning solution and thus protect the items to be cleaned from graying. Cleaning enhancers may also be anti-corrosive additives or non-ionic or cationic surfactants for handle improvement with "easy finish" properties or finishes. Some cleaning agents provide sanitary effects in the textile care, others reduce or avoid the static charge of the items to be cleaned during the drying phase, causing e.g. in wool linting is significantly reduced.

Bei bestimmten Ausführungsformen der erfindungsgemäßen Verwendung des Lösungsmittelsgemäß Patentanspruch 1 weist das Reinigungsmittel auch einen Anteil einer für chemische Reinigungsmittel geeigneten Substanz zum Abfangen von Wasserstoffprotonendonatoren, freien Wasserstoffprotonen und/oder freien Carbonylverbindungen auf. Beispielsweise kann durch Zusatz von hierfür geeigneten basischen Verbindungen das Reinigungsmittel dadurch stabilisiert werden, daß eventuell vorhandene Protonendonatoren in einer Neutralisationsreaktion abgefangen werden und nicht zu einer protonenkatalysierten Zersetzung des Lösungsmittels beitragen können.In certain embodiments of the inventive use of the solvent according to claim 1, the cleaning agent also comprises a proportion of a substance suitable for chemical cleaning agents for trapping hydrogen proton donors, free hydrogen protons and / or free carbonyl compounds. For example, the detergent can be stabilized by the addition of suitable basic compounds, that any existing proton donors are trapped in a neutralization reaction and can not contribute to a proton-catalyzed decomposition of the solvent.
Die vorgenannten für chemische Reinigungsmittel geeigneten Substanzen zum Abfangen von Wasserstoffprotonendonatoren, freien Wasserstoffprotonen und/oder freien Carbonylverbindungen können ohne Beschränkung hierauf ausgewählt sein unter Alkalicarbonaten, wie z.B. Natrium- oder Kaliumcarbonat, und Verbindungen, die eine oder mehrere freie Aminogruppen tragen, wie z.B. Chitin, Harnstoff, Aminoguanidin, Phenylbiguanidin, (polymere) Aminophenole und Aminoguppen tragende Ionentauscher. Die Verbindungen, die eine oder mehrere freie Aminogruppen tragen, sind dazu in der Lage, Carbonylverbindungen unter Bildung von Schiffschen Basen (Azomethine) zu binden. Gleichzeitig reagieren diese Aminoverbindungen als Basen und reagieren mit Protonendonatoren in einer Neutralisationsreaktion unter der Bildung von Amoniumverbindungen. Durch diese pH-Stabilisierung werden gegebenenfalls auftretende säurekatalysierte Hydrolysereaktionen, die zur Zersetzung des Lösemittels führen, verhindert oder zumindest deutlich eingeschränkt.The aforesaid chemicals suitable for chemical cleaning agents for trapping hydrogen proton donors, free hydrogen protons and / or free carbonyl compounds may be selected therefrom without limitation to alkali metal carbonates, such as Sodium or potassium carbonate, and compounds bearing one or more free amino groups, such as chitin, urea, aminoguanidine, phenylbiguanidine, (polymeric) aminophenols, and ion exchangers bearing amino groups. The compounds bearing one or more free amino groups are capable of binding carbonyl compounds to form Schiff bases (azomethines). At the same time, these amino compounds react as bases and react with proton donors in a neutralization reaction to form ammonium compounds. This pH stabilization prevents or at least significantly restricts any acid-catalyzed hydrolysis reactions which lead to decomposition of the solvent.
Die für chemische Reinigungsmittel geeigneten Substanzen zum Abfangen von Wasserstoffprotonendonatoren, freien Wasserstoffprotonen und/oder freien Carbonylverbindungen sind vorzugsweise höhersiedend als die übrigen Substanzen des Reinigungsmittels und temperaturstabil, so daß sie bei der Destillation des chemischen Reinigungsmittels in der Destillationsblase zurückbleiben und nicht mit dem Reinigungsgut in Verbindung kommen. Sind die Verbindungen in dem Reinigungsmittel nicht löslich, so können sie alternativ auch in das in einem Vorratstank aufbewahrte Reinigungsmittel gegeben werden, so daß sie auch in diesem Fall nicht mit dem Reinigungsgut in Kontakt kommen. Die Abfangreaktion von Protonen und Carbonylverbindungen geschieht hier in einer heterogenen Reaktion und ist auch bei nichtdestillierenden Reinigungsprozessen denkbar.The substances suitable for chemical cleaning agents for trapping hydrogen proton donors, free hydrogen protons and / or free carbonyl compounds are preferably higher boiling than the other substances of the cleaning agent and temperature stable, so that they remain in the distillation of the chemical cleaning agent in the distillation still and not with the cleaning material in combination come. If the compounds are not soluble in the cleaning agent, they may alternatively be added to the cleaning agent stored in a storage tank, so that they do not come into contact with the cleaning material in this case either. The trapping reaction of protons and carbonyl compounds takes place here in a heterogeneous reaction and is also conceivable in non-distilling purification processes.
