Embodiment 1

[0068] Embodiment 1, preparation Mo 3 S 7 (Henki 2 dtc) 2 (S 2 )

[0069] Methanol (50 mL), dioctylamine (0.66 mL, 2.2 mmol) and carbon disulfide (0.13 mL, 2.2 mmol) were mixed and stirred in a 250 mL round bottom flask under nitrogen atmosphere for 2 hours. join (NH 4 ) 2 Mo 3 S 13 (750 mg, 1 mmol) and the mixture was heated to reflux overnight. The red solid in the mixture was removed by heating and methanol was decanted from the red solid. The solid was washed with methanol, dried, dissolved in toluene and filtered. Toluene was removed by vacuum distillation to obtain a dark red transparent solid product whose elemental analysis corresponds to that of Mo 3 S 7 (Henki 2 dtc) 2 (S 2 ).

Embodiment 2

[0070] Embodiment 2 prepares Mo 3 S 7 (coco-based 2 dtc) 2 (S 2 ):

[0071] Methanol (50 mL), dicocoamine (1.00 g, 2.2 mmol) and carbon disulfide (0.13 mL, 2.2 mmol) were combined and stirred in a 250 mL round bottom flask under nitrogen atmosphere for 2 hours. To the solution was added (NH 4 ) 2 Mo 3 S 13 (750 mg, 1 mmol). The mixture was heated to reflux overnight. The solution was removed with heat and the methanol was decanted from the red solid. The solid was washed with methanol and dried. The product was dissolved in toluene and filtered. Toluene was distilled off in vacuo to obtain a dark red transparent solid.

Abstract

A lubricating oil composition is provided comprising a major amount of an oil of lubricating viscosity and a minor amount of, as an additive, at least one compound comprising a polynuclear molybdenum core and bonded thereto one or more anionic ligands capable of rendering the compound oil-soluble or oil-dispersible, wherein the ratio of the number of molybdenum atoms in the core to the number of said ligands is 1:1, such as 3:2 or greater.

Description

field of invention [0001] The present invention relates to lubricating oil compositions and concentrates containing metal core compounds, particularly polynuclear molybdenum core compounds. Background technique [0002] Certain oil-soluble or oil-dispersible metal core compounds, i.e. metal core compounds having one or more ligands bound to them, are known as additives (or additive components) for lubricating oil compositions (or lubricant) to enhance the properties and performance of the composition. The ligand or ligands render the compound oil soluble. For example, certain oil-soluble molybdenum and sulfur-containing compounds have been proposed and tested as lubricant additives. Molybdenum- and sulfur-containing compounds are described in the patent specifications of US-A-2,951,040; -3,419,589; -3,840,463; -4,966,719; -4,995,966; [0003] Molybdenum compounds described in the art for use as lubricant additives are primarily dinuclear molybdenum compounds, typically Mo...
