  • Alkyl phosphate amine salts for use in lubricants
    Patent number: 11384308
    Abstract: A lubricant composition comprising an oil of lubricating viscosity and 0.01 to 5 percent by weight of a substantially sulfur-free alkyl phosphate amine salt, where at least 30 mole percent of the phosphorus atoms are in an alkyl pyrophosphate salt structure, exhibits good antiwear performance. In the phosphate amine salt, at least 80 mole percent of the alkyl groups are typically secondary alkyl groups of 3 to 12 carbon atoms.
    Type: Grant
    Filed: July 17, 2017
    Date of Patent: July 12, 2022
    Assignee: The Lubrizol Corporation
    Inventors: William R. S. Barton, Daniel J. Saccomando, Jamal Kassir, Paul E. Adams, Lisa Blanazs, Michael R. Sutton, Stephen J. Cook, Paul R. Vincent, Ewan E. Delbridge, Yanshi Zhang
