Es ist bekannt, Arylamine und Thiodiarylamine als Antioxydationsmittel in synthetischen Schmiermitteln
für Flugzeugturbinenmotoren einzusetzen, wobei auch schon ihre kombinierte Anwendung empfohlen worden
ist, um die an sich geringere Antioxydationswirkung gewisser substituierter Phenothiazine zu erhöhen.
Es wurde nunmehr gefunden, daß Triarylester der Phosphorthionsäure zwar nicht allein als Antioxydationsmittel
in synthetischen Esterschmierölen wirksam sind, aber in Kombination mit Arylaminen und
Thiodiarylaminen in Esterschmierölen in synergetischer Weise hinsichtlich der Erhöhung der Oxydationsbeständigkeit
zusammenwirken und zu besseren Ergebnissen als die bekannten Schmieröle
führen.
Das erfindungsgemäße Schmieröl auf der Basis von aliphatischen Carbonsäureestern, enthaltend ein Gemisch
eines Arylamins und eines Thiodiarylamins, ist dadurch gekennzeichnet, daß es zusätzlich einen Triarylester
der Phosphorthionsäure der Formel, vorzugsweise in Mengen von 0,5 bis 10 Gewichtsprozent,
bezogen auf das Schmieröl
Schmieröl
S = P
in welcher R Wasserstoff oder ein Alkylrest mit bis zu 8 Kohlenstoffatomen ist, enthält.
Die Arylreste der Phosphorthionsäure enthalten vorzugsweise nicht mehr als 14 Kohlenstoffatome.
Beispiele: Triphenyl-, Tritolyl-, Tribenzyl-, Trixylyl-, und Trioctylphenylphosphorthionate. Triphenylphosphorthionat
wird jedoch bevorzugt angewendet.
Diese Triarylester können in Konzentrationen zwischen 0,5 und 10 Gewichtsprozent, vorzugsweise
zwischen 2,0 und 7,0 Gewichtsprozent, bezogen auf das fertige Schmierölgemisch, vorliegen.
Beispiele für Arylamine sind Phenyl-c^naphthylamin
und Alkylderivate dieser Verbindung. Beispiele für Thiodiarylamine sind Phenothiazin und 3,7-Dioctylphenothiazin.
Diese Arylamine und Thiodiarylamine werden in Mengen von 0,5 und 5,0 Gewichtsprozent, Vorzugsweise
von 1,0 und 3,0 Gewichtsprozent, bezogen auf das Schmieröl, zugesetzt.

Als Basisschmieröl werden aliphatische Carbonsäureestern verwendet. Geeignete Ester sind die aliphatischen
Ester aus einer einbasischen Carbonsäure mitA bis 18 Kohlenstoffatomen im Molekül und einem
Glykol mit 4 bis 20 Kohlenstoffatomen je Molekül, beispielsweise Ester aus Neopentylglykol, 2-Butyl-2-äthyl-l,3-propandiol
bzw. Dipropylenglykol und Heptansäure, n-Octansäure bzw. Pelargonsäure.
Bevorzugt sind Ester aus Monocarbonsäuren mit 4 bis 18 Kohlenstoffatomen im Molekül, wie Buttersäure
und Pelargonsäure, mit mehrwertigen Alkoholen mit 4 bis 12 Kohlenstoffatomen pro Molekül,
z. B. Pentaerythritol oder Trimethylolpropan, z. B. Pentaerythritoltetrabutyrat und Trimethylolpropantrihepthylat.
Auch Mischungen dieser Ester sind verwendbar.
Die erfindungsgemäßen Schmieröle können auch andere bekannte Zusatzstoffe, wie Hochdruckmittel,
Verdickungsmittel, Mittel gegen Lackbildung, Antischaummittel, Farbstoffe, Antikorrosionsmittel und
weitere Antioxydationsmittel, enthalten.
Der synergistische Effekt der erfindungsgemäßen Kombination ist aus den Tabellen I und II (IX bis
XIV sind erfindungsgemäße Schmieröle, I bis VIII sind Schmieröle nach dem Stand der Technik) ersichtlich.
Für die Prüfung der Gemische wurde der nachstehend beschriebene Rolls Royce Blown Oxidation
Test verwendet, "bei welchem die Wirkung des Anti-
809 5ÖJ/299
Oxydationsmittels in Änderungen der Viskosität und des Säurewertes zum Ausdruck kommt. Die entsprechenden
Versuchsergebnisse sind in Tabelle II zusammengestellt.
Rolls Royce Blown Oxidation Test
Unter kontrollierten Bedingungen werden durch eine Probe von 50 ml des zu untersuchenden Öls bei
einer Temperatur von 220°C während eines Zeitraumes von 192 Stunden 250 ml pro Minute mit
Wasserdampf gesättigte Luft oder Stickstoff hindurchgeleitet. Die infolge der Oxidation eintretende Zer-Setzung
des Schmierölgemisches wird dann bestimmt durch die Änderung des Säurewertes, durch Änderungen
der Viskosität und durch den Gehalt an in Benzol unlöslichen Bestandteilen.

Durch die Zahlenwerte von Tabelle II wird bestätigt, daß durch die Anwesenheit eines Triarylesters
der Phosphorthionsäure, welcher bei alleiniger Anwendung in einem solchen synthetischen Esterschmieröl
praktisch keine Wirkung als Antioxydationsmittel zeigt (vgl. Beispiele II bis V), die Oxydationsbeständigkeit
eines solchen Esterschmieröles, welches außerdem Arylamine und Thiodiarylamine enthält, ganz wesentlich
verbessert wird. Diese Erhöhung der Oxydationsbeständigkeit kommt in der Verringerung des Anteiles
an in Benzol unlöslichen Bestandteilen, in den Werten für die Viskositätserhöhung und in den Werten für die
Erhöhung des Säuregrades bei dem vorstehend beschriebenen Oxydationstest zum Ausdruck (vgl. Beispiele
IX bis XIV).
Auch ist die erfindungsgemäß erzielte Verbesserung wesentlich größer als bei Anwendung anderer bekannter
Antioxydationsmittel (vgl. Beispiele VII und VIII).
