But you can also without using a Nuancierfarbstoffs work.

    Die Aufhellung der textilen Materialien erfolgt in der Regel nach dem Auszieh- oder Thermosolverfahren. The lightening of the textile materials is usually after the exhaust or thermosol process.

    Im Ausziehverfahren arbeitet man in wässriger Flotte meist bei Temperaturen von 90 bis 135, üblicherweise um 130°C. Im Falle des Applizierens über 100°C muss in einem Autoklaven, einem Hochdruckapparat oder einer Hochdruckmaschine gearbeitet werden. Das Thermosol-Verfahren wird bei atmosphärischem Druck angewendet.The exhaust process usually works in an aqueous liquor Temperatures from 90 to 135, usually around 130 ° C. In the case of Application above 100 ° C must in an autoclave, a high pressure apparatus or a high pressure machine. The thermosol process is used at atmospheric pressure.

    Beim Ausziehverfahren wird in der Regel das aufzuhellende textile Material bei einer Temperatur von 10 bis 35°C in eine wässrige Flotte gebracht, das die optisch aufhellend wirkenden Verbindungen, gegebenenfalls einen blauen oder violetten Nuancierfarbstoff oder eine Mischung derselben und gegebenenfalls Zuschlagstoff, z.B. Dispergiermittel, Carbonsäuren oder Alkalispender, enthält und dessen pH-Wert meist 3 bis 12, vorzugsweise 3 bis 8, beträgt. Das Flottenverhältnis (Gewichtsverhältnis textiles Material : Flotte) beträgt dabei 1:3 bis 1:40, vorzugsweise 1:5 bis 1:20. Das Bad wird dann innerhalb von 15 bis 30 Minuten auf eine Temperatur von 90 bis 130°C, vorzugsweise 95 bis 100°C, erhitzt und 15 bis 60 Minuten bei dieser Temperatur gehalten. Danach wird das aufgehellte textile Material gespült und getrocknet.In the exhaust process is usually the aufhellende textile Material at a temperature of 10 to 35 ° C in an aqueous Fleet brought that the optically brightening acting Compounds, optionally a blue or purple Nuancierfarbstoff or a mixture thereof and optionally Aggregate, e.g. Dispersants, carboxylic acids or alkali donors, contains and its pH is usually 3 to 12, preferably 3 to 8, is. The liquor ratio (weight ratio of textiles Material: liquor) is 1: 3 to 1:40, preferably 1: 5 to 1:20. The bath will then be within 15 to 30 minutes to a temperature of 90 to 130 ° C, preferably 95 to 100 ° C, heated and held at this temperature for 15 to 60 minutes. After that The lightened textile material is rinsed and dried.

    Beim Thermosol-Verfahren wird üblicherweise das aufzuhellende textile Material mit einer wässrigen Flotte, die den optischen aufhellende Substanzen, gegebenenfalls einen blauen oder violetten Nuancierfarbstoff oder Mischungen derselben und gegebenenfalls Zuschlagstoff (s.o.) enthält, foulardiert. Die Flottenaufnahme beträgt im Allgemeinen 50 bis 100%. Danach wird das textile Material getrocknet und bei einer Temperatur von 150 bis 200°C für 5 bis 60 Sekunden fixiert.In the thermosol process is usually brightening textile material with an aqueous liquor that is the optical lightening substances, possibly a blue or purple Nuancierfarbstoff or mixtures thereof and optionally Contains aggregate (s.o.), padded. The fleet intake is generally 50 to 100%. Thereafter, the textile Dried material and at a temperature of 150 to 200 ° C for Fixed for 5 to 60 seconds.

    Als Dispergiermittel verwendet man bevorzugt solche Dispergiermittel, die farblos sind und bei Temperaturen bis mindestens 210°C gegen Vergilbung stabil sind.The dispersants used are preferably those dispersants, which are colorless and at temperatures up to at least 210 ° C stable against yellowing.

    Besonders geeignete Dispergiermittel sind z.B. anionische oder nichtionische, insbesondere solche aus der Klasse der Ethylenoxidaddukte mit Fettalkoholen, höheren Fettsäuren oder Alkylphenolen oder Ethylendiamin-Ethylenoxid-Propylenoxidaddukte.Particularly suitable dispersants are e.g. anionic or nonionic, especially those from the class of ethylene oxide adducts with fatty alcohols, higher fatty acids or alkylphenols or ethylene diamine-ethylene oxide-propylene oxide adducts.

    • Die Herstellung der Verbindungen IV und V ist bekannt und erfolgt vorteilhaft durch Umsetzung der Phenole VI bzw. VII

    Figure 00230001
    mit Propylenoxid und folgender Umsetzung des Adduktes mit Ethylenoxid oder durch Umsetzen von VI bzw. VII mit Ethylenoxid. Anschließend kann man die Addukte mit Chlorsulfonsäure oder Schwefeltrioxid vollständig oder partiell zu Schwefelsäurehalbester umsetzen und die erhaltenen Halbester mit alkalisch wirkenden Mitteln neutralisieren.The preparation of compounds IV and V is known and is advantageously carried out by reacting the phenols VI or VII
    Figure 00230001
    with propylene oxide and subsequent reaction of the adduct with ethylene oxide or by reacting VI or VII with ethylene oxide. Then you can react the adducts with chlorosulfonic acid or sulfur trioxide completely or partially to sulfuric acid half ester and neutralize the half ester obtained with alkaline agents.

    Die Phenole der Formel VI bzw. VII können durch Umsetzen von Bisphenol A (2,2-(p,p'-Bishydroxydiphenyl)propan) oder Phenol mit 4 bzw. 2 mol Styrol in Gegenwart von Säure als Katalysator erhalten werden. Dabei werden die Phenole VI bzw. VII nach bekannten Verfahren zuerst mit Propylenoxid und anschließend mit Ethylenoxid oder nur mit Ethylenoxid in Gegenwart von sauer oder alkalisch wirkenden Katalysatoren, beispielsweise mit NaOCH3 oder mit SbCl5, zu den entsprechenden Oxalkylierungsprodukten IV bzw. V mit d = 0 umgesetzt. Die Oxalkylierung kann z.B. nach dem in der US 2,979,528 beschriebenen Verfahren erfolgen.The phenols of the formula VI or VII can be obtained by reacting bisphenol A (2,2- (p, p'-bishydroxydiphenyl) propane) or phenol with 4 or 2 mol of styrene in the presence of acid as catalyst. In this case, the phenols VI or VII by known methods first with propylene oxide and then with ethylene oxide or only with ethylene oxide in the presence of acidic or alkaline catalysts, for example with NaOCH 3 or with SbCl 5 , to the corresponding alkoxylation IV or V with d = 0 implemented. The alkoxylation can be carried out, for example, by the process described in US Pat. No. 2,979,528.

    Die Schwefelsäurehalbester werden durch Reaktion der Oxalkylierungsprodukte mit Chlorsulfonsäure oder Schwefeltrioxid hergestellt, wobei die Menge an Chlorsulfonsäure oder Schwefeltrioxid so gewählt wird, dass alle freien Hydroxylgruppen oder nur ein gewisser Prozentsatz sulfatiert wird. Im letzteren Falle entstehen Gemische aus Verbindungen der Formel IV bzw. V, die freie und sulfatierte Hydroxylgruppen enthalten. Zur Verwendung als Tenside werden die bei der Umsetzung erhaltenen Halbester der Schwefelsäure in wasserlösliche Salze überführt. Als solche kommen vorteilhaft die Alkalimetallsalze, z.B. die Natrium- oder Kaliumsalze, in Betracht. Dabei sind im Falle von Chlorsulfonsäure zwei Äquivalente, bei Schwefeltrioxid ein Äquivalent basisch wirkender Verbindungen erforderlich. Als letztere verwendet man zweckmäßigerweise wässriges Alkalimetallhydroxid. Bei der Neutralisation sollte die Temperatur 70°C nicht überschreiten. Die erhaltenen Salze können in Form von wässrigen Lösungen oder auch als solche isoliert und in fester Form verwendet werden.The sulfuric acid half esters are obtained by reaction of the alkoxylation products made with chlorosulfonic acid or sulfur trioxide, the amount of chlorosulfonic acid or sulfur trioxide is chosen so that all free hydroxyl groups or only one a certain percentage is sulfated. In the latter case arise Mixtures of compounds of formula IV or V, the free and Contain sulfated hydroxyl groups. For use as surfactants become the obtained in the reaction half ester of sulfuric acid converted into water-soluble salts. As such, benefit the alkali metal salts, e.g. the sodium or potassium salts, into consideration. In the case of chlorosulfonic acid are two Equivalent, one equivalent of basic sulfur trioxide Connections required. As the latter, it is expedient to use aqueous alkali metal hydroxide. In neutralization the temperature should not exceed 70 ° C. The obtained salts may be in the form of aqueous solutions or else be isolated as such and used in solid form.

    Bevorzugt sind Dispergiermittel IV bzw. V, bei denen a 0 bis im Mittel 2,5, b im Mittel 25 bis 250 und d 0 bis im Mittel 0,5 ist. Besonders bevorzugt sind Dispergiermittel IV bzw.
