Description
Gegenstand des Patents 865 339 sind Schmieröle, die durch einen Gehalt an öllöslichen Zinksalzen
von Carbonsäuren mit mindestens 5 Kohlenstoffatomen im Molekül und an öllöslichen Umsetzungsprodukten von Phosphorpentasulfid mit organischen
Hydroxylverbindungen gekennzeichnet sind.
Gegenstand des Patents 934 184 sind Schmieröle, die an Stelle der öllöslichen Zinksalze von Carbonsäuren
mit mindestens 5 Kohlenstoffatomen im Molekül öllösliche Erdalkalisalze schwefelhaltiger
Carbonsäuren mit mindestens 5, zweckmäßig io oder mehr Kohlenstoffatomen im Molekül· enthalten.
Gegenstand des Patents 934 185 sind Schmieröle, die an Stelle der öllöslichen Zinksalze von Carbonsäuren
mit mindestens 5 Kohlenstoffatomen im Molekül Ester von schwefelhaltigen Carbonsäuren
mit mindestens 5, zweckmäßig 10 oder mehr Kohlenstoffatomen im Molekül enthalten.
Es wurde gefunden, daß die Schmieröle an Stelle der öllöslichen Umsetzungsprodukte von Phosphorpentasulfid
mit organischen Hydroxylverbindungen öllösliche Umsetzungsprodukte Von Phosphorpentasulfid
mit flüssigen oder festen aliphatischen Kohlenwasserstoffen oder Terpenkohlenwasserstoffen
enthalten können.
Als Kohlenwasserstoffe für die Umsetzung mit Phosphorpentasulfid verwendet man z. B. Paraffinkohlenwasserstoffe,
wie Diisobutylen, Polyisobutylen, Olefine, die durch Krackung von Paraffin oder Erdölfraktionen oder durch Chlorwasserstoff-
abspaltung aus chlorierten Erdölfraktionen oder Paraffinen erhalten wurden. Von Terpenkohlenwasserstoffen
kommen beispielsweise Terpentinöl, von Einzelkohllenwasserstoffen z. B. Pinen, Camphen
od. dgl. in Betracht.
250 g eines durch Erhitzen einer Mischung von 50% Spermöl und 50% Spermölfettsäure mit 14%
(bezogen auf die Mischung) gemahlenem Schwefel unter Rühren auf 2000, Raffination unter -Zusatz
von 8% Bleicherde bei 1500 und Abfiltrieren oder Abschleudern der Bleicherde erhaltenen Gemisches
aus geschwefeltem Ester und Fettsäure mit 12 bis I3fl/o Schwefelgehalt werden mit 670 g Motorenöl
bei ioo° gerührt. Dann werden 25 g Zinkoxyd zugegeben
und die Temperatur auf i6o° gesteigert. Dann gibt man 180 g eines Bariumsalzes einer
Thiophosphorsäure zu, das -in bekannter Weise durch Einwirkung von Phosphorpentasulfid auf
a-Pinen bei 50 bis 1300 hergestellt wurde. Nach
Zugabe von 15 g Calciumoxyd wird die Temperatur auf i8o° erhöht. Nach Filtrieren oder Schleudern
wird das Erzeugnis mit geringen Mengen gebranntem Kalk, Wasser und Methanol bei 80 bis 1300
alkalisch gemacht.
Nach dem Zentrifugieren erhält man etwa 1 kg
eines Schmierölverbesserungsmittd's mit sehr guten Detergent- und Inhibitoreigenschaften.
