Description

Es wurde bereits vorgeschlagen, Umsetzungsprodukte von Molybdänhalogeniden mit organischen Schwefelverbindungen Mineralschmierölen zur Verbesserung der Druckfestigkeit zuzusetzen.It has already been proposed that reaction products of molybdenum halides with organic Adding sulfur compounds to mineral lubricating oils to improve compressive strength.

Ferner wurde vorgeschlagen, Thiomolybdate stickstoffhaltiger Basen und Molybdänalkylxanthogenate als Zusatzstoffe für Schmieröle zu verwenden.It has also been suggested that thiomolybdates contain nitrogen To use bases and molybdenum alkyl xanthates as additives for lubricating oils.

Es wurde gefunden, daß hochbelastbare Schmieröle erhalten werden, wenn man dem Schmieröl eine öllösliche Metallkomplexverbindung zusetzt, die aus dem Halogenid eines Metalls der II. bis VIII. Gruppe des Periodischen Systems — ausgenommen Molybdän — und einer organischen Schwefelverbindung, dieSchwefel in Thioester-, Thioäther-, Thioamid-, Thioimid- oder Disulfidbindung enthält, erhalten worden ist.It has been found that heavy-duty lubricating oils are obtained if the lubricating oil is an oil-soluble one Metal complex compound is added, which consists of the halide of a metal of the II. To VIII. Group of the Periodic Table - except molybdenum - and an organic sulfur compound, the sulfur contains in thioester, thioether, thioamide, thioimide or disulfide bond, has been obtained.

Im allgemeinen zeigen die erfindungsgemäßen Komplexverbindungen in dem Schmieröl geringere Korrosionswirkungen als die einzelnen Komponenten. Die Anwendung der Komplexverbindung erfolgt durch Lösung in einem Grundöl mineralischer oder nicht mineralischer Herkunft.In general, the complex compounds according to the invention show less corrosive effects in the lubricating oil than the individual components. The complex compound is applied by Solution in a base oil of mineral or non-mineral origin.

Als Metallhalogenide für die Herstellung öllöslicher Metallkomplexverbindungen eignen sich insbesondere Titantrichlorid, das Di-, Tri- oder Tetrachlorid des Vanadins, Niob- und Tantalchlorid, Manganchlorid, Eisen-(2)-chlorid oder Eisen-(3)-chlorid bzw. die entsprechenden Bromide sowie Aluminiumchlorid, Zinn-(2)-chlorid, Zinn-(4)-chlorid und Vanadinoxychlorid. Die in den folgenden Beispielen beschriebenen Versuche wurden mit einem mineralischen Grundöl vom Typ SAE 20 mit einem Wert in der Almen-Wieland-Maschine (AWM) von 160 kg und im Vierkugelapparat (VKA) von 160 kg durchgeführt.As metal halides for the production of oil-soluble Metal complex compounds are particularly suitable titanium trichloride, the di-, tri- or tetrachloride des Vanadium, niobium and tantalum chloride, manganese chloride, iron (2) chloride or iron (3) chloride or the corresponding Bromides as well as aluminum chloride, tin (2) chloride, tin (4) chloride and vanadium oxychloride. The experiments described in the following examples were made with a mineral base oil from Type SAE 20 with a value in the Almen-Wieland machine (AWM) of 160 kg and in the four-ball apparatus (VKA) of 160 kg.

Gibt man 4 Gewichtsteile Eisen-Butylxanthogenat zu 100 Gewichtsteilen des obengenannten Grundöles, so erhält man ein Schmieröl mit einem VKA-Wert von 400 kg.If 4 parts by weight of iron butyl xanthate are added to 100 parts by weight of the above-mentioned base oil, the result is a lubricating oil with a VKA value of 400 kg.

Desgleichen erhöhen Nickel-Isobutylxanthogenat und Nickel-Dibutyldithiocarbaminat in derselbenKonzentration angewandt den VKA-Wert auf '400 kg, während Eisen-(2)-äthylhexylxanthogenat einen VKA-Wert von 480 kg ergibt.Likewise increase nickel isobutyl xanthate and nickel dibutyldithiocarbaminate in the same concentration applied the VKA value to '400 kg, while Iron (2) ethylhexyl xanthate gives a VKA value of 480 kg.

Oxydiert man 24 Gewichtsteile Benzylmerkaptan in 100 Gewichtsteilen Butanol mit 16 Gewichtsteilen Eisen-(3)-chlorid unter Durchleiten von Sauerstoff bei 50 bis 60° C, so erhält man nach dem Einengen des Butanols ein Komplexsalz, das ein Molekül Eisenchlorid auf ein Molekül Dibenzyldisulfid neben etwas Kristallbutanol enthält. Gibt man 2 Gewichtsteile dieses Komplexsalzes zu 100 Gewichtsteilen des genannten Grundöles, so erhält man ein Schmieröl mit dem AWM-Wert von 1950 bis 2050 kg und dem VKA-Wert von 1050 kg bei einer Verschleißkalotte von 2 mm Durchmesser.If 24 parts by weight of benzyl mercaptan are oxidized in 100 parts by weight of butanol with 16 parts by weight of iron (3) chloride while passing oxygen through 50 to 60 ° C, a complex salt is obtained after concentrating the butanol, which is one molecule of iron chloride contains one molecule of dibenzyl disulfide in addition to some crystal butanol. If you give 2 parts by weight of this Complex salt to 100 parts by weight of the base oil mentioned, a lubricating oil is obtained with the AWM value from 1950 to 2050 kg and the VKA value of 1050 kg with a wear cap of 2 mm Diameter.

Gibt man 4 Gewichtsteile eines aus Eisen-(3)-chlorid und Guanidinrhodanid in Butanol hergestellten Komplexsalzes zu 100 Gewichtsteilen eines Polyglykols mit den Grundwerten AWM = 650 kg und VKA = 140 kg, so erhöht sich der AWM-Wert auf 1650 bis 1700 kg und der VKA-Wert auf 480 kg. Der Durchmesser der Verschleißkalotte beträgt 2,2 mm.4 parts by weight of a complex salt prepared from iron (3) chloride and guanidine thiocyanide in butanol are added to 100 parts by weight of a polyglycol with the basic values AWM = 650 kg and VKA = 140 kg, the AWM value increases to 1650 to 1700 kg and the VKA value to 480 kg. The diameter of the The wear cap is 2.2 mm.
