Description

  • Schmiermittel Es wurde gefunden, daß man Schmiermittel aus Ölen, Fetten, Fettalkoholen., Fettsäuren oder Wachsen tierischer oder pflanzlicher Herkunft dadurch wesentlich verbessern kann, daß man denselben Ester aus Naphthensäuren und Glycerin zusetzt. Die Glycerinester der Naphth@ensäuren zeichnen sich durch hohe Viscosität und weiterhin durch die Fähigkeit aus, mit den zuvor genannten Stoffen außerordentlich gut verträglich zu sein. Durch die Zugabe von Naphthensäureglyoerinester wird den eingangs erwähnten Schmiermitteln die Fähigkeit verliehen, auch bei tieferen Temperaturen nicht zu stocken und ihre volle Schmierfähigkeit zu behalten. Außerdem lassen sich mit den genannten Naphthensäureestern dünnflüssigere Schmiermittel in ihrer Viscosität ganz erheblich verbessern, ohne daß man gezwungen ist, zu Produkten zu greifen, die, wie beispielsweise die Seifen, wegen ihres Aschengehaltes; ihres Gelatinierungsvermögens sowie ihres hohen Stockpunktes in der Praxis unerwünscht sind. Bei den als Zusatz zu Schmiermitteln vorgeschlagenen Naphthensäureestern des Glycerins ist @es nicht in allen Fällen erforderlich, daß sämtliche Hydroxylgruppen dies Alkohols durch Naphthensäuren verestert sind. Je nach dem Verwendungszweck können dieselben auch teilweise unverestert bzw. mit anderen Carbonsäuren verestert sein. Beispiel Vermischt man ein Klauenöl vom Stockpunkt o' C mit 25 Gewichtsprozent Glycerintrinaphthenat (Trübungspunkt unter-25- C). so erhält man eine Mischung, die erst bei - i o° C zu stocken beginnt.
