Claims11
A multifunctional lubricant additive composition providing friction reduction, oxidation resistance and dispersancy, which comprises the product of the process of reacting at a temperature of from 50.degree.-500.degree. C. an olefin having 10-10,000 carbon atoms with about 0.1 to about 20 moles of sulfur or a sulfur-yielding compound per mole of the olefin to form a sulfurized olefin;
- reacting the sulfurized olefin at a temperature of from 50.degree.-400.degree. C. with 0.1 to 20.0 moles of a polyamine to form an aminated sulfurized olefin and reacting the aminated sulfurized olefin at a temperature of from 50.degree.-300.degree. C. with about 0.1 to 10.0 moles of a molybdenum compound per mole of the olefin to form the additive composition.
A multifunctional lubricant additive composition providing friction reduction, oxidation resistance, and dispersancy, which comprises the reaction product of (a) an olefin having from 10 to 10,000 carbon atoms;
- (b) a polyamine having the formula NH.sub.2 [(CH.sub.2).sub.z NH].sub.x H, wherein z is an integer from 2 to 12 and x is an integer from 1 to 10, and wherein z is from 2 to 6 when x is from 2 to 10;
- (c) sulfur or a sulfur-yielding compound and (d) a molybdenum compound;
- wherein the olefin is reacted with said sulfur or sulfur-yielding compound at a temperature of from 50.degree.-500.degree. C. to form a sulfurized olefin, the sulfurized olefin is reacted with the polyamine at a temperature of from 50.degree.-400.degree. C. to form an aminated sulfurized olefin, and the aminated sulfurized olefin is reacted with the molybdenum compound at a temperature of from 50.degree.-300.degree. C.
