Description
- Schmierölzusatzstoff Es ist bekannt, daß der Zusatz von ortho- oder para-Nitroanilin zu Schmierölen deren Schmiereigenschaften verbessert. Werden z. B. zu ioo g eines Grundöles, das für sich auf der Almen-Wieland-Maschine eine Belastung bis 400 kg verträgt, z,¢ g para-Nitroanilin zugegeben, so kann die Belastung bis 1500 kg erhöht werden.
- Es wurde nun gefunden, daß der Zusatz von para-Amino-para'-nitrodiphenylsulfid (NH2-C,H4-S-CFH4-N02) wesentlich stärker die Druckschmiereigenschaften von Schmieröl verbessert. Schon sehr kleine Mengen, z. B. Bruchteile eines Prozentes, der genannten Verbindung, bewirken eine erhebliche Verbesserung. Wird zwecks Erzielung einer höheren Wirkung beabsichtigt; größere Mengen von der genannten Verbindung zuzusetzen, als in dem betreffenden Schmieröl bei gewöhnlicher Temperatur löslich sind - diese Mengen hängen von der" Herkunft bzw. dem .Charakter des Schmieröles ab -, so können Lösungsvermittler, z. B. Wollfett, höhere Fettalkohole, Abietinol, Pölyglykoläther, Polyglykolester u. dgl., mitverwendet werden. Auch der Zusatz von Schaumverhinderungsmitteln, z. B. von Siliconölen, ist häufig vorteilhaft.
- Um Hochdruckschmieröle zur Schmierung von Getrieben oder anderen unter hoher Druckbelastung stehenden Maschinenteilen herzustellen, kann man para-Amino-para'-nitrodiphenylsulfid allein oder zusammen mit bekannten Hochdruckschmierzusätzen verwenden, z. B. mit ortho- oder para-Nitroanilin, ortho- oder meta-Dinitrobenzol, organischen Halogenverbindungen, wie Chlorparaffinen, Chlorphenolen, Chloranil, ferner mit Phosphorpentasulfid-Umsetzungsprodukten von Olefinen, Hydroxylverbindungen (Alkoholen, Alkylphenolen, Alkylphenolsulfiden, hydroxylgruppenhaltigen Alkylphenolsulfidestern), Fettsäuren, Fettsäureestern, Sulfonsäuren, Aminen, Nitrilen oder mit Metall- oder Aminsalzen solcher Phosphorpentasulfid-Umsetzungsprodukte oder mit Phosphatiden, z. B. Lecithin.
- Das para-Amino-para'-nitrodiphenylsulfid kann mit Vorteil auch HD-Motorenölen zugesetzt werden, die durch Zumischung von sogenannten Detergents' (d. h. Stoffen, die auf Grund ihres Dispergiervermögens die beim Betrieb von Benzin- oder Dieselmotoren im Öl entstehenden oder ins Öl gelangenden Verunreinigungen in Schwebe zu halten und so den Motor rein zu halten vermögen) sowie Oxydations- und Korrosionsverhinderern und gegebenenfalls weiteren Zusätzen, wie Schaumverhinderern, Stockpunktserniedrigern und V. L-Verbesserern, zu mineralischen Grundölen hergestellt werden. Auch in diesen Ölen beeinflußt das para-Amino-para'-nitrodiphenylsulfid das Verhalten der Öle gegenüber unter hohem Druck stehenden Motorenteilen, wie Lagern und Ventilstößeln, günstig. Beispielsweise wirkt sich der beanspruchte Zusatz vorteilhaft aus in Ölen, die in den folgenden Patentschriften beschrieben sind: Deutsche Patentschriften 843 281, 865 339, 874 9I2, 879 443, 896 349, 914 007, 922 533, 922 847, 923 984 sowie Gegenstand der Patente 99,9 383, 934 184 und 934 185 sind.
- Beispiel = In verschiedenen Proben eines aus deutschem Erdöl stammenden Schmieröles mit einer Viskosität von I4,3° E bei 50° C werden verschiedene Mengen para-Amino-para'-nitrodiphenylsulfid bis zur Lösung erwärmt. Nach dem Abkühlen werden die Proben auf der Almen-Wieland-Maschine geprüft, wobei sich die aus der folgenden Tabelle ersichtlichen Belastungen ergeben:
Beispiel 2 In einem Motorenöl vom Viskositätsbereich SAE 2o aus deutschem Erdöl werden 4,5 Gewichtsprozent eines Stoffgemisches entsprechend Beispiel 2 der deutschen Patentschrift 879 443 unter Erwärmen gelöst. In zwei Proben dieses Öles von HD-Qualität werden o,2 bzw. 0,4 Gewichtsprozent para-Aminopara'-nitrodiphenylsulfid in der Wärme gelöst. Auf der Almen-Wieland-Maschine ergeben sich folgende Werte:Zusatzstoff Almen-Wieland- Menge Maschine Art I in % in kg - - 200 ortho-Nitroanilin ........ 1,0 1450 para-Amino-para'-nitro- diphenylsulfid ....... o,= 700 dgl. 0,5 950 dgl. 1,0 1700 Beispiel 3 ZumBetrieb eines Ottomotors wurde ein o,04 VOlumprozent Bleitetraäthyl enthaltendes Benzin verwendet. Die Schmierung des Motors erfolgte mit einem Hochleistungsöl (HD-Öl), dessen Temperatur zwecks scharfer Prüfung des Öles auf Korrosionswirkung gegenüber den Bleibronzelagern auf =3o° C gehalten wurde. Vor jedem Prüflauf ließ man den Motor mit dem zu prüfenden Öl 8 Stunden einlaufen. Dann wurde nach 24 und 48 Stunden Betrieb der Lagergewichtsverlust bestimmt. Die Werte sind in der untenstehenden Tabelle zusammengestellt.Zusatzmenge Almen-Wieland-Maschine in % in kg 0,0 goo 0,2 1350 0,4 1450 - Basisöl war' ein deutsches selektiv hochraffiniertes Motorenöl vom Viskositätsbereich SAE 2o. Diesem Ö1 wurde HD-Qualität erteilt durch Zugabe eines Detergents .auf Octylphenolsulfidbasis (Barium-Verbindung) und eines Oxydations- und Korrosionsverhinderers auf Dialkyl-dithiophosphorsäureesterbasis (Zinksalz aus Cocosalkohol-Phosphorpentasulfid-Umsetzüngsprodukt). Diese Stoffe wurden im Gewichtsverhältnis 5 : 4 zugegeben, und zwar in solcher Menge, daß das Öl 0,40/, Asche enthält.
- Das HD-Öl wurde für sich sowie mit verschiedenen Zusatzstoffen geprüft, wobei zum Vergleich sowohl ortho-Nitroanilin als auch das in der britischen Patentschrift 455 305 als Schmierölzusatz empfohlene 2, 4-Dinitrophenylthiocyanat herangezogen wurden. Das para-Amino-para'-nitrodiphenylsulfid ergab die besten Verschleißwerte.
