Description
Schmiermittel Es wurde gefunden, daß man Ester der allgemeinen Formel R'-S02 NR"'-R""-COO-R" als Schmiermittel für sich oder zusammen mit anderen Schmierstoffen, insbesondere anderen Estern mit schmierenden Eigenschaften und bzw. oder Kohlenwasserstoffölen, verwenden kann. In dieser Formel bedeuten R', R" und R"" gesättigte aliphatische Kohlenwasserstoffreste mit gerader oder verzweigter Kette, wobei R"" mindestens a, R' vorzugsweise q. bis 8 und R" vorzugsweise 8 bis 1q. Kohlenstoffatome enthält und R"' eine organische Gruppe bedeutet.Lubricants It has been found that esters of the general formula R'-S02 NR "'- R" "- COO-R" as a lubricant on its own or together with other lubricants, in particular other esters with lubricating properties and / or hydrocarbon oils, can use. In this formula, R ', R "and R" "represent saturated aliphatic ones Hydrocarbon radicals with a straight or branched chain, where R "" is at least a, R 'preferably q. to 8 and R "preferably contains 8 to 1q. carbon atoms and R "'represents an organic group.
Die Ester können beispielsweise nach den Verfahren der Patente 873 088 und 912 333 hergestellt werden. Sie sind für sich oder in Mischung mit den genannten Stoffen gute Schmiermittel, die sich durch große Beständigkeit gegen hohe Temperaturen auszeichnen. Filme aus diesen Schmiermitteln sind sehr druckfest und halten den höchsten Belastungen stand. Die Ester haben weiterhin die Eigenschaft, Metalle gegen Korrosion zu schützen, die durch atmosphärische Einflüsse, insbesondere Feuchtigkeit, oder durch Säuren bewirkt wird. So schützen sie beispielsweise bei Verwendung in Verbrennungsmotoren gegen die schädlichen Einwirkungen der sauren Oxydationsprodukte, die häufig beim Betrieb der Motoren entstehen.The esters can be prepared, for example, by the methods of patents 873,088 and 912,333. They are good lubricants on their own or in a mixture with the substances mentioned, which are characterized by their high resistance to high temperatures. Films made from these lubricants are very pressure-resistant and can withstand the highest loads. The esters also have the property of protecting metals against corrosion caused by atmospheric influences, in particular moisture, or by acids. For example, when used in internal combustion engines, they protect against the harmful effects of acidic oxidation products that often arise when the engines are operated.
Durch entsprechende Auswahl der Gruppen R', R", R' und R"" hat man es in der Hand, die Eigenschaften der neuen Schmiermittel, z. B. ihre Flüchtigkeit und ihren Flammpunkt sowie auch ihr Verhalten gegenüber tiefen Temperaturen; in gewünschter Weise einzustellen. Die Unempfindlichkeit gegenüber tiefen Temperaturen wird um so größer, je mehr verzweigte .Ketten das Molekül enthält und je stärker diese Ketten verzweigt sind.By appropriate selection of the groups R ', R ", R' and R" "one has it in hand, the properties of the new lubricant, z. B. their volatility and their flash point as well as their behavior towards low temperatures; in set as desired. Insensitivity to low temperatures becomes so larger, the more branched .Ketten the molecule contains and the stronger these chains are branched.
Die in dem nachfolgenden Beispiel angegebenen Teile sind Gewichtsteile.The parts given in the following example are parts by weight.
Beispiel Man vermischt 4o Teile eines durch Polymerisation von Äthylen gewonnenen Oles, das eine Viskosität von iio° E bei 2o° und einen unter -35° liegenden Stockpunkt hat, mit 6o Teilen eines Esters der Adipinsäure mit einer von i80 bis 25o° siedenden Fraktion der bei der Kohlenoxydhydrierüng unter Druck gebildeten höheren Alkohole und 8 Teilen des im Beispiel i des Patents 9z2 333 beschriebenen Esters. Die Mischung hat eine Viskosität von 12° E bei 2o°, einen Stockpunkt unter - 5o° und den Flammpunkt 22o°. Sie hat ausgezeichnete schmierende Eigenschaften. Durch den Zusatz des Esters nach Beispiel i des Patents 912 333 wird im Vierkugelapparat ein Anstieg der Belastung von 16o auf 22o kg/cm2 erreicht. Außerdem verhindert der Zusatz Korrosionen an mit dem C51 geschmierten Metallteilen. Eisenbleche, die mit diesem 01 behandelt und 4 Wochen lang bei Zimmertemperatur einer Atmosphäre von 98% relativer Feuchtigkeit ausgesetzt wurden, zeigten keinerlei Veränderungen.EXAMPLE 40 parts of an oil obtained by polymerization of ethylene, which has a viscosity of 10 ° E at 20 ° and a pour point below -35 °, are mixed with 60 parts of an ester of adipic acid with a fraction of 180 to 25o ° higher alcohols formed in the carbon dioxide hydrogenation under pressure and 8 parts of the ester described in example i of patent 9z2 333. The mixture has a viscosity of 12 ° E at 2o °, a pour point below -5o ° and a flash point of 22o °. It has excellent lubricating properties. The addition of the ester according to example i of patent 912 333 increases the load in the four-ball apparatus from 160 to 220 kg / cm2. In addition, the additive prevents corrosion on metal parts lubricated with the C51. Iron plates, treated with this 01 and 4 weeks at room temperature of an atmosphere of 98% RH were exposed, showed no changes.
