SchmierölLubricating oil
Es ist bekannt, daß organische Disulfide in Schmieröle eingearbeitet werden können und daß hierdurch dieHöchstdruckeigenschaften der Schmieröle verbessert werden. Es wurde nun gefunden, daß die Höchstdruckeigenschaften verbessert werden, wenn ein Schmieröl 0,1 bis 6,0 Gewichtsprozent, vorzugsweise 1 bis 3 Gewichtsprozent, eines Thiolsulfinats der allgemeinen FormelIt is known that organic disulfides can be incorporated into lubricating oils and that thereby the maximum pressure properties of the lubricating oils be improved. It has now been found that the extreme pressure properties are improved, when a lubricating oil is 0.1 to 6.0 weight percent, preferably 1 to 3 weight percent, of a thiol sulfinate the general formula
R-S(O)n-S-RRS (O) n -SR
worin R einen Alkylrest mit bis zu 4 C-Atomen oder einen Phenylrest und η 1 oder 2 bedeutet, enthält.where R is an alkyl radical with up to 4 carbon atoms or a phenyl radical and η is 1 or 2, contains.
Besonders geeignete Verbindungen sind n-Butyl-(n-butanthiolsulfinat) und Phenyl-(benzolthiolsulfinat). Als Schmieröle werden vorzugsweise solche aus Erdöl, z. B. aus Mittelost-Rohölen, verwendet.Particularly suitable compounds are n-butyl (n-butanethiolsulfinate) and phenyl (benzenethiol sulfinate). The lubricating oils are preferably those made from petroleum, e.g. B. from Middle Eastern crude oils used.
Nachstehend werden als Beispiel zwei Höchstdruckschmieröle gemäß der Erfindung beschrieben.Two extreme pressure lubricating oils according to the invention are described below as an example.
Das Schmieröl war ein Vakuumdestillat eines Mittelost-Rohöls. Das raffinierte Öl hatte eine Viskosität von 73,8 cSt bei 60° C.The lubricating oil was a vacuum distillate of a Middle Eastern crude oil. The refined oil had a viscosity of 73.8 cSt at 60 ° C.
Schmieröl mit einem Zusatz von 3 Gewichtsprozent n-Butyl-(n-butanthiolsulfinat). Dieses wurde nach dem Verfahren, das im Journal of the American Chemical Society, 69, S. 1710 (1947), beschrieben ist, aus Di-(n-butyl)-disulfid hergestellt.Lubricating oil with an addition of 3 percent by weight of n-butyl (n-butanethiol sulfinate). This was after the method described in the Journal of the American Chemical Society, 69, p. 1710 (1947), made from di (n-butyl) disulfide.
Schmieröl mit einem Zusatz von 4,3 Gewichtsprozent Phenyl-(benzolthiolsulfinat)Lubricating oil with an addition of 4.3 percent by weight phenyl (benzene thiol sulfinate)
Beide Öle wurden mit dem Vierkugel-Prüfgerät geprüft.Both oils were tested with the four-ball tester.
Prüfmethode gemäß U. S. Federal Test Method Standard No. 791 a.Test method according to U.S. Federal Test Method Standard No. 791 a.

Zum Vergleich wurden zwei weitere Schmieröle mit 3 Gewichtsprozent Di-(n-butyl)-disulfid und 4,0 Gewichtsprozent Diphenyldisulfid geprüft.For comparison, two other lubricating oils with 3 percent by weight of di (n-butyl) disulfide and 4.0 percent by weight diphenyl disulfide tested.

Es ist festzustellen, daß die Produkte nach Beispielen 1 und 2 eine höhere Druckaufnahmefähigkeit haben als die Vergleichsöle.It can be seen that the products according to Examples 1 and 2 have a higher pressure absorption capacity than the comparison oils.
