FIELD: chemistry.
SUBSTANCE: invention relates to a molybdate ester represented by the following formula:
.
In said formula: R1 represents a hydrocarbon chain containing from 11 to 21 carbon atoms, R2 represents either a hydrogen atom or a hydrocarbon chain containing from 1 to 20 carbon atoms, and m and n independently range from 1 to 5. Also disclosed is a compound used as an additive to lubricating oil, lubricating compositions and a method of producing a molybdate ester.
EFFECT: disclosed molybdenum compound is effective when used in a lubricating composition in an amount sufficient to create a concentration of about 50–5000 mln-1 of molybdenum in the lubricating composition, with respect to reducing friction and wear, at the same time providing improved protection against copper and lead corrosion.
