Abstract
A composition of matter represented by the following formula: where R1 is an unsaturated or branched hydrocarbon chain, R2 is either a hydrogen atom or a hydrocarbon chain, and m and n are independently from 1 to 5, when used in a lubricating composition, being effective for friction and wear reduction, while providing improved protection against copper and lead corrosion in an engine.
Claims8
A lubricating composition comprising at least 80% of a lubricating base oil and 0.01-5 weight % of an additive compound represented by the following formula:
- where R1 is an unsaturated or branched hydrocarbon chain, R2 is either a hydrogen atom or a hydrocarbon chain, and m and n are independently from 1 to 5.
A lubricating composition comprising at least 80% of a lubricating base oil and 0.01-5 weight % of an additive being a mixture of compounds represented by the following formula:
- wherein said mixture comprises at least one first compound having a hydrocarbon chain which is unsaturated or branched, and at least one second compound having a hydrocarbon chain which is saturated and unbranched;
- and where R2 is either a hydrogen atom or a hydrocarbon chain, and m and n are independently from 1 to 5.
