Description

Verfahren zur Herstellung von Zinnverbindungen von Alkylphenolsulfiden oder -disulfiden Man hat schon vorgeschlagen, Zinnverbindungen von Alkylphenolsulfiden oder -disulfiden zur Verbesserung von Schmierölen zu verwenden. Es hat sich nämlich gezeigt, daß bei Zusatz kleiner Mengen dieser Stoffe zu Schmierölen die Bildung schädlicher Überzüge auf dem Kolben und in den Kolbenringnuten des Motors verhindert wird.Process for the preparation of tin compounds of alkylphenol sulfides or disulfides It has already been proposed to use tin compounds of alkylphenol sulfides or disulfides to improve lubricating oils. Because it has has shown that when small amounts of these substances are added to lubricating oils, the formation prevents harmful coatings on the piston and in the piston ring grooves of the engine will.

Die Herstellung der Zinnverbindungen geschah bisher in der Weise, daß man Alkylphenolsulfideoder -disulfide mit Zinnpulver bei erhöhter Temperatur behandelte. Dabei treten jedoch nur etwa 2 bis 30/0 Zinn in die Alkylphenolsulfide ein. Da man bei höherem Zinngehalt stärkere Inhibitorwirkung erzielt, hat man versucht, durch Einwirkung von Zinnchlorid auf die Alkaliverbindungen der Sulfide größere Mengen Zinn einzuführen. Dies gelang auch, aber die so erhaltenen Zinnverbindungen sind verhältnismäßig schwer in Schmieröl löslich und kommen somit nicht voll zur Geltung.The production of the tin compounds has so far been carried out in such a way that one alkylphenol sulfides or disulfides with tin powder at elevated temperature treated. However, only about 2 to 30/0 tin enter the alkylphenol sulfides a. Since a higher inhibitory effect is achieved with a higher tin content, attempts have been made to larger due to the action of tin chloride on the alkali compounds of the sulphides To import quantities of tin. This also succeeded, but the tin compounds obtained in this way are relatively difficult to dissolve in lubricating oil and therefore do not come to the fore Validity.

Es wurde nun gefunden, _daß man Zinnnverbindungen von Alkylphenolsulfiden oder -disulfiden, die auch bei verhältnismäßig hohem Zinngehalt in Schmieröl gut löslich sind, gewinnt, wenn man Lösungen von Alkylphenolsulfiden oder -disulfiden in Kohlenwasserstoffen mit Stannohydroxyd auf Temperaturen oberhalb 23o°, vorteilhaft 24o bis 270°, erhitzt. Will man dabei dieAnwendungvonerhöhtem Druck vermeiden, so benutzt man als Lösungsmittel Kohlenwassersto#e,, dig über der, genantiken Temperatur sieden; z. B. Schmieröle. Dre`h Filtrieren oder Zentrifugieren werden die ungelösten Stoffe abge. trennt, und es wird ein zinnfaltiges Alkylphenolsulfid in konzentrierter Lösung erhalten, die sich ohne weiteres dem Schmieröl zumischen läßt.It has now been found that tin compounds of alkylphenol sulfides are made or disulfides, which work well even with a relatively high tin content in lubricating oil are soluble, wins if one uses solutions of alkylphenol sulfides or disulfides in hydrocarbons with stannous hydroxide at temperatures above 230 °, advantageous 24o to 270 °, heated. If you want to avoid the use of increased pressure, then do so is used as a solvent Hydrocarbons, dig over the, simmering temperature; z. B. Lubricating Oils. Turn filtration or centrifugation the undissolved substances are removed. separates, and it becomes a tin-fold alkylphenol sulfide obtained in concentrated solution, which easily mix with the lubricating oil leaves.

Als Ausgangsstoffe für die Herstellung derenannten.Inhibitoren verwendet man z. B. die doch Einwirkung von S Cl= oder S= Cl= auf Isobutyl-, L39# amyl-, Heptyl-, Isooctyl-, Decyl- oder Octadetyv phenol oder auf Gemische dieser Alkylphenole erlltliehen Alkylphenolsulfide oder -disulfide. Auch die Alkylphenolgemische, die durch Alkylierung von Phenol mit chlorierten Erdölfraktionen oder chlorierten Paraffinen mit Hilfe von Aluminiumchlorid hergestellt werden; lassen sich durch Behandlung mit Schwefelchloriden in geeignete Ausgangsstoffe verwandeln.As starting materials for the production of their named.Inhibitoren are used, for. B. the action of S Cl = or S = Cl = on isobutyl, amyl, heptyl, isooctyl, decyl or octadetyl phenol or on mixtures of these alkylphenols results in alkylphenol sulfides or disulfides. Also the alkylphenol mixtures, which are produced by alkylating phenol with chlorinated petroleum fractions or chlorinated paraffins with the aid of aluminum chloride; can be converted into suitable starting materials by treatment with sulfur chlorides.

Das Stannohydroxyd, das vorteilhaft in frisch gefällten Form verwendet wird; aber nicht völlig trocken sein muB, wird unter schwachem Erwärmen in Schmieröl gelöst. Die Lösung wird dann nach Erwärmen auf etwa 12o bis i 5o' nach und nach mit Stannohydroxyd versetzt, wobei anhaftendes Wasser und ein Teil des Reaktionswassers entweichen; der größte Teil deS 54&4wbydroxyds aber noch ungelöst bleibt. Sobald das durch das Entweichen des Wassers verursachte Schäumen aufhört; erhitzt man, vorteilhaft unter Rühren, auf Temperaturen über 23o°; z. B. auf 250 bis 270°N Hierbei löst sich die Hauptmenge des Stannöhydroxyds leicht auf. Die Mischung wird dann, gegeben enfglls nach Verdünnen mit anderen Lösungsmitteln, filtriert oder zentrifugiert. Aus dem Filtrat wird das Verdünnungsmittel durch Destillieren entfernt. The stannous hydroxide, which is advantageously used in freshly precipitated form; but does not have to be completely dry, is dissolved in lubricating oil with gentle heating. The solution is then heated to about 12o to 15o 'and gradually admixed with stannous hydroxide, whereby adhering water and part of the water of reaction escape; Most of the 54 & 4wbydroxyds, however, remains unsolved. As soon as the foaming caused by the escape of the water stops; heated, advantageously with stirring, to temperatures above 230 °; z. B. to 250 to 270 ° N Here, the main amount of Stannöhydroxyds dissolves easily. The mixture is then filtered or centrifuged, if necessary after dilution with other solvents. The diluent is removed from the filtrate by distillation.

Das neue Verfahren Ermöglicht es, erhebliche Mengen Zinn, z.: t. i Atom Zinn, in i Mol Alkylphenolsulfid einzuführen. Trotz dieses hohen Zinngehalts sind die Produkte in Schmieröl leicht löslich. Durch entsprechende Bemessung der zugesetzten Stannohydroxydmenge kann man auch Produkte herstellen, in denen ein Teil der phenolischen Hydroxylgruppen, z: B. ro bis 20°/e davon, nicht durch Zinn ersetzt ist: Solche Produkte wirken gleichzeitig auch als Oxydationsverhinderer. Die Produkte nach der Erfindung,können gcgebenenfalls zusammen mit anderen @Schmiecölverhesserungsmitteln angewandt werden.The new process enables considerable amounts of tin, e.g .: t. i atom of tin to introduce in i mole of alkylphenol sulfide. Despite this high tin content, the products are easily soluble in lubricating oil. By appropriately measuring the amount of stannous hydroxide added, it is also possible to produce products in which some of the phenolic hydroxyl groups, e.g. ro to 20% thereof, are not replaced by tin: such products also act as antioxidants. The products according to the invention can optionally be used together with other lubricating oil improvers.

Beispiel ,66 Gewichtsteile Diisobutylphenolsulfid werden . unter leichtem Erwärmen in 132 Gewichtsteilen Molprenschmieröl gelöst. Nach weiterem Erwärmen der 'LAsung auf 130 bis iso° trägt man unter Rühren allmählich 3o Gewichtsteile weißes getrocknetes S ,znnohydroxyd ein. Nach dem Aufhören des Se`häumens erhitzt man unter weiterem Rühren schnell auf 26o° und hält diese Temperatur etwa io Minuten lang aufrecht. Nach dem Abkühlen auf i20 bis i50° wird abgesaugt, wobei nur geringe Mengen Ungelöstes auf dem Filter zurückbleiben.Example , 66 parts by weight of diisobutylphenol sulfide will be. dissolved in 132 parts by weight of molpr lubricating oil with gentle heating. After the solution has been heated further to 130 to ISO °, 30 parts by weight of white, dried sodium hydroxide are gradually introduced with stirring. After the se'häumens has stopped, the mixture is quickly heated to 26o ° while continuing to stir, and this temperature is maintained for about 10 minutes. After cooling to 120 to 150 °, it is suctioned off, with only small amounts of undissolved material remaining on the filter.

Setzt man von dem so gewonnenen Filtrat i bis 5% einem Motorenschmieröl zu, das zur' Schmierung von Dieselmotoren dient, so wird die Abschei-Jung eines lackartigen Überzugs auf dem Kolben des Motors sowie das Stecken der Kolbenringe verhindert.If 1 to 5% of the filtrate obtained in this way is used in an engine lubricating oil to, which is used for the 'lubrication of diesel engines, so the parting boy becomes one lacquer-like coating on the piston of the engine and the sticking of the piston rings prevented.

Ähnlich gut wirkende Stoffe erhält man, wenn man statt des Diisobutylphenolsulfids die äquimolekulare Menge Diisobutylphenoldisulfid verwendet oder Produkte, die durch Kondensieren von chloriertem Paraffin (Chlorgehalt etwa 15 %) mit Phenol in Gegenwart von Aluminiumchlorid und Behandeln des Kondensationsprodukts mit Schwefelchloriden hergestellt wurden.Substances that work just as well are obtained if you use diisobutylphenol sulfide instead of diisobutylphenol the equimolecular amount of diisobutylphenol disulfide used or products made by Condensation of chlorinated paraffin (chlorine content about 15%) with phenol in the presence of aluminum chloride and treating the condensation product with sulfur chlorides were manufactured.
