Claims
- 1. A product of reaction, which demonstrates enhanced antiwear properties combined with effective friction reducing properties in a synergistic effect when added to lubricants and greases, made by reacting for a period of at least one hour in a ratio of from about 1:9 to 9:1, at a temperature between 70.degree. C. and 100.degree. C., antimony diamyl dithiocarbamate and molybdenum di-2-ethvlhexyl dithiophosphate.
- 2. A lubricant composition comprising a lubricating oil or a grease prepared therefrom, and an effective friction-reducing properties in a synergistic effect of a reaction product made by reacting for a period of at least one hour in a ratio of from about 1:9 to 9:1 at a temperature between 70.degree. C. and 100.degree. C., antimony diamyl dithiocarbamate and molybdenum di-2-ethylhexyl dithiophosphate.
- 3. The lubricant composition of claim 2, wherein the reactants are combined to form the reaction product prior to addition to the lubricating oil.
- 4. The composition of claim 2, wherein the lubricating oil is a natural oil of lubricating viscosity, a synthetic oil of lubricating viscosity, or a mixture of both synthetic and natural oils.
- 5. The composition of claim 4, wherein the natural oil is selected from the group consisting of paraffinic oils, naphthenic oils, neutral distillates and bright stocks.
- 6. The composition of claim 4, wherein the synthetic oil is selected from the group consisting of polyolefins, polyglycols, esters of dibasic acids, and esters of polyols.
- 7. A process for the production of a lubricant additive possessing the synergism of antiwear and antifrictional properties, wherein antimony diamyl dithiocarbamate and molybdenum di-2-ethvlhexyl dithiophosphate are reacted at atmospheric pressure in a temperature range between 70.degree. C. to 100.degree. C.
