  • Patent number: 7935663
    Abstract: Novel molybdenum compounds are prepared by reacting a hindered amine with a molybdenum source, in the presence of one of (a) water, (b) a diol and water, and (c) the reaction product of a fatty oil and a multifunctional amine, and water. Lubricant compositions containing these new compounds are more stabilized against oxidation and have improved friction reducing properties. Synergy is observed when the novel compounds are combined with a diaryl amine in a lubricant composition.
