Description

Schmieröl F?s ist bekannt, daß man die Viskosität eines Schmieröles und dessen Vis'kositätsindex dadurch verbessern kann, daß man ihm geringe Mengen polymere sauerstoffhaltige Vinylverbindungen zusetzt.Lubricating Oil F? S is known that the viscosity of a lubricating oil and its viscosity index can be improved by giving it small amounts polymeric oxygen-containing vinyl compounds added.

Es wurde nun gefunden, daß öllösliche polymere sauerstoffhaltige Vinylverbindungen, die gleichzeitig Schwefel und Phosphor enthalten, den Viskositätsindex und den Stockpunkt von Sch.mier-5len besonders günstig .beeinflussen und außerdem verhindern, daß sich im Schmieröl Schlamm absetzt.It has now been found that oil-soluble polymeric oxygen-containing vinyl compounds, which contain sulfur and phosphorus at the same time, the viscosity index and the pour point von Sch.mier-5len particularly favorably and also prevent sludge settles in the lubricating oil.

:11s :,1,usgangsstoffe für die -genannten Schmieröl-@-erbesserungsmittel dienen Polymerisationsprodukte von Fettsäurevinylestern, Vinyläthern ges'ittigter und ungesättigter Alkohole, von alkyliertem Styrol, von Isobutylen, Acrylsäure, Methacrylsäure und deren Derivaten oder auch von Gemischen dieser Stoffe. Die Polymerisationsprodukte der Fettsäurevinylester werden zweckmäßig aus höheren Fettsäuren, wie Ölsäure, Stearinsäure oder. Palmitinsäure und Alkoholen hergestellt. Man kann auch Polyvinylalkohole mit Fettsäuren oder Al.de-.hyden umsetzen. Als Alkohole für die Herstellung der Vinyläther eignen sich solche mit drei und mehr Koihilenstoffatomen, z. B. Butyl- oder Oleylalkdhol. Die Polymerisationsprodukte der Acryl- oder Methacrylsäureester können aus gesättigten oder ungesättigten Alkoholen von niedrigem oder zweckmäßig 'höherem Molekulargewicht hergestellt seien.: 11s:, 1, starting materials for the-mentioned lubricating oil - @ - improvers serve polymerization products of fatty acid vinyl esters, saturated vinyl ethers and unsaturated alcohols, from alkylated styrene, from isobutylene, acrylic acid, Methacrylic acid and its derivatives or mixtures of these substances. The polymerization products the fatty acid vinyl esters are expediently made from higher fatty acids such as oleic acid and stearic acid or. Palmitic acid and alcohols produced. You can also use polyvinyl alcohols Implement fatty acids or Al.de-.hyden. As alcohols for the production of vinyl ethers are those with three or more Koihilenstoffatomen, z. B. butyl or oleyl alcohol. The polymerization products of the acrylic or methacrylic acid esters can be obtained from saturated or unsaturated alcohols of low or suitably higher molecular weight are made.

Die gemannten Polyvinylverbindun.gen werden zur Gewinnung von schwefel- und p'hosphorlhaltigen Stoffen z. B. mit 5 bis 30°/0, vorteilhaft 15 bis 250/0, P'hospihorpentasülfid bei 5o bis 300°, vorteilhaft 12o bis 23o°, 1>ehande,lt. Man erhält so, Reäktions- Produkte, die i bis 200/0, insbesondere i bis 12% Schwefel, und 0,5 bis ioo/o, insbesondere o,51> s 5% Phosphor enthalten.The manned polyvinyl compounds are used to extract sulfur and p'hosphorlhaltigen substances z. B. with 5 to 30 ° / 0, advantageously 15 to 250/0, P'hospihorpentasülfid at 5o to 300 °, advantageously 12o to 23o °, 1> hand, according to. Man receives so, reaction Products that i to 200/0, especially i up to 12% sulfur, and 0.5 to 100%, in particular 0.51> 5% phosphorus.

Die schwefel- und phosphorhaltigen Polymerisationsprodukte werden Schmierölen oder Schmierfetten in Mengen von etwa o,5 'bis io% zugegeben. Zweckmäßig gibt man gleichzeitighöhermofe'kulare inetall- und schwefelhaltige organische Verbindungen zu, wie die S.ulfonate von Barium, Calcium, Zinn, Aluminium, Magnesium, Zink oder Blei. Beispiel ioo Teile Polyvinyloleylätiher werden mit 8 Teilen Phosphorpentasulfid und io Teitlen Bleicherde verrührt und innerhalb von _5 Stunden auf 150 bis 22o° erhitzt. Nach Abfil'trieren der festen Stoffe erhält man ein Produkt, (las i.5°/0 Phosphor und 2% Schwefel enthält. Dieses wird in einer Menge von 0,3% einem Dieselmotorenöl zugegeben, wodurch dessen Neigung zur Oxydation und zum Ringstecken wesentlich verringert wird.The sulfur- and phosphorus-containing polymerization products are added to lubricating oils or greases in amounts of about 0.5 to 10%. It is expedient to add more highly molten metal and sulfur-containing organic compounds at the same time, such as the sulfonates of barium, calcium, tin, aluminum, magnesium, zinc or lead. EXAMPLE 100 parts of polyvinyl oleyl ether are stirred with 8 parts of phosphorus pentasulphide and 10 parts of fuller's earth and heated to 150 ° to 220 ° over the course of 5 hours. After filtering off the solids, a product is obtained (which contains i.5% phosphorus and 2% sulfur. This is added in an amount of 0.3% to a diesel engine oil, which significantly increases its tendency to oxidize and stick is decreased.
