Es wurde gefunden, daß Schmieröle nach Patent 865 339 sowie den Patenten 934 184, 934 185 und 941 687, die als weiteren Bestandteil die an sich als Schmierölzusätze bekannten Alkylphenol-It has been found that lubricating oils according to patent 865 339 and patents 934 184, 934 185 and 941 687, which contain the alkylphenol, known per se as lubricating oil additives, as a further component

sulfide oder derenEster und bzw. oder Sulfonsäuren enthalten, die Bildung kohlenstoffhaltiger Ablagerungen auf den Kolben des Motors in besonders hohem Maße verhindern.sulfides or their esters and / or sulfonic acids, the formation of carbonaceous deposits on the piston of the engine to a particularly high degree.

Als Alkylphenolsulfide kommen Mono- oder Disulfide in Betracht, in denen die Schwefelbrücke gleiche oder verschiedene Alkylphenolreste verbindet, z. B. Kresol-, Xylenol-, Isobutylphenol-, Isoamylphenol·, Hexylphenol-, Heptylphenoli-, Octylphenol-, Dodecylphenol- und Octodecylphenolreste. Auch Phenole, die mit chlorierten Erdölfraktionen oder chloriertem Paraffin oder mit entsprechenden Olefinen alkyliert worden sind, oder 'solche, die die Alkylreste verzweigter Alkohole aus der Isobutyl-. alkoholsynthese enthalten, können als Grundstoff für die Alkylphenolsulfide dienen. Diese können noch weitere Sufestittfenten enthalten, z. B. Carboxylgruppen, funktionell veränderte halogenfreie Carboxylgruppen, wie Ester- oder Amidgruppen, ao sowie Ätherreste enthaltende Substituenten. Die Alkylphenolsulfide können ganz oder teilweise mit ein- oder mehrbasischen Säuren verestert werden. Man verwendet hierbei z. B. natürliche Fettsäuren, wie Palmitinsäure oder Stearinsäure, ferner die Fettsäuren, die bei der Oxydation von Paraffin und ähnlichen Kohlenwasserstoffen in der flüssigen Phase entstehen. Auch sind diejenigen Säuren brauchbar,, die man durch Oxydation der bei der Umsetzung von Oxyden des Kohlenstoffs mit Wasserstoff gebildeten höheren Alkohole erhält, ferner die Säuren, die durch Einwirkung von Kohlenoxyd' und Wasser auf Olefing entstehen, und-"? ferner auch mehrbasisch« Säuren, wie Oxalsäure, Bernsteinsäure, Glutarsäure, Adipinsäure und Korksäure. Mit Vorteil wird die Veresterung derart durchgeführt, daß noch freie Hydroxylgruppen mwerestert bleiben, um in diese Ester noch Metalle, die oben genannt sind, einführen zu können. Als .Sulfonsasien eignen sich öllösliche Erdölsulfonsäuren, zweckmäßig cyclische Sulfonsäuren.Suitable alkylphenol sulfides are mono- or disulfides in which the sulfur bridge connecting identical or different alkylphenol radicals, e.g. B. cresol, xylenol, isobutylphenol, Isoamylphenol, hexylphenol, heptylphenol, octylphenol, Dodecylphenol and octodecylphenol residues. Also phenols made with chlorinated petroleum fractions or chlorinated paraffin or have been alkylated with corresponding olefins, or 'those which the Alkyl radicals of branched alcohols from the isobutyl. Containing alcohol synthesis can be used as a raw material serve for the alkylphenol sulfides. These can also contain other Sufestittenten, z. B. carboxyl groups, functionally modified halogen-free carboxyl groups, such as ester or amide groups, ao as well as substituents containing ether residues. The alkylphenol sulfides can be wholly or partially with monobasic or polybasic acids are esterified. One uses here z. B. natural fatty acids, like palmitic acid or stearic acid, furthermore the fatty acids which are involved in the oxidation of paraffin and similar hydrocarbons arise in the liquid phase. Also those are acids useful, which one can use by oxidation of the reaction of oxides of carbon with Hydrogen formed higher alcohols, also the acids obtained by the action of Carbon monoxide and water are formed on olefins, and- "? also polybasic acids such as oxalic acid, succinic acid, glutaric acid, adipic acid and Suberic acid. The esterification is advantageously carried out in such a way that there are still free hydroxyl groups mwerestert to stay in these esters yet Metals, which are mentioned above, to be able to import. Oil-soluble petroleum sulfonic acids are suitable as sulfonic acids, expediently cyclic sulfonic acids.

mit einer oder mehreren Alkylgruppen, die 6 bis 15 Köhlenstoffatome in der Alkylgruppe enthalten, insbesondere ihre Salze.with one or more alkyl groups containing 6 to 15 carbon atoms in the alkyl group, especially their salts.

• Die Mischung der Komponenten wird in der Weise vorgenommen, daß man etwa 40 bis 70% -öllösliche Erdalkalisalze schwefelhaltiger Carbonsäuren oder deren Ester, 10 bis 20 % der Umsetzungsprodukte von Phosphorsulfiden mit Kohlenwasserstoffen und 10 bis 40% Alkylphenolsulfid verwendet. Dieses Gemisch wird einem Schmieröl in einer Menge von 0,1 bis 10 % zugegeben. Gleichzeitig kann man noch Schaumverhinderungsmittel, Stockpunktserniedriger und Viskositätsverbesserer zusetzen.• The components are mixed in such a way that about 40 to 70% - Oil-soluble alkaline earth salts of sulfur-containing carboxylic acids or their esters, 10 to 20% of the reaction products of phosphorus sulfides with hydrocarbons and 10 to 40% alkylphenol sulfide used. This mixture is added to a lubricating oil in an amount of 0.1 to 10%. Simultaneously Antifoaming agents, pour point depressants and viscosity improvers can also be used to add.

Beispielexample

Dann gibt man 180 Teile eines Bariumsalzes aus einem Umsetzungsprodukt von Terpentinöl mit Phosphorperitasulfid zu, das bei 50 bis 1300 hergestellt wurde. Dieses Produkt wird mit geringen Mengen gebranntem Kalk, Wasser und Methanol bei 80 bis 1300 behandelt und dabei leicht alkalisch gemacht.130 parts of propyl ester of a sperm oil, which was treated with ground sulfur at approximately 200 0 refined with bleaching earth, 60 parts of the barium compound of Heptylphenolsulfid and 60 parts of an oil-soluble zinc-calcium salt of dodecylbenzenesulfonic acid are dissolved in 670 parts of motor oil at ioo °. Are then added to 180 parts of a barium salt of a reaction product of turpentine with Phosphorperitasulfid prepared at 50 to 130 0th This product is treated with small amounts of quick lime, water and methanol at 80 to 130 0 thereby made slightly alkaline.
