Patent number: 5538520Abstract: Polyalkylene amine coupled heterocyclic compounds are effective multifunctional additives, providing cleanliness to fuels and lubricants as well as anti-wear, friction-modifying, thermal and oxidative stabilizing properties. The beneficial effects of the product of the instant invention apparently result from an internal synergism between the polyalkylene amine groups and the heterocyclic groups.Type: GrantFiled: March 25, 1994Date of Patent: July 23, 1996Assignee: Mobil Oil CorporationInventors: Noyes L. Avery, Joan C. Axelrod, James T. Carey, John Hiebert, Andrew G. Horodysky

Patent number: 5512190Abstract: The present invention provides a lubricating oil additive which provides anti-wear properties to a lubricating oil. The additive is the reaction product of 2,5-dimercapto-1,3,4-thiadiazole and a mixture of unsaturated mono-, di-, and tri-glycerides. The present invention also provides a lubricating oil additive with anti-wear properties produced by reacting a mixture of unsaturated mono-, di-, and tri-glycerides with diethanolamine to provide an intermediate reaction product and reacting the intermediate reaction product with 2,5-dimercapto-1,3,4-thiadiazole.Type: GrantFiled: August 22, 1994Date of Patent: April 30, 1996Assignee: Texaco Inc.Inventors: Gregory P. Anderson, Julian H. Dancy, Doris Love, Jayne M. Lucas
