Claims23
A hydrocarbon-soluble and molybdenum-containing composition which comprises the reaction product of:
- (a) a hydrocarbon-soluble polyamine derivative selected from the group consisting of Mannich products and dicarboxylic acid-polyamine reaction products;
- (b) a molybdenum compound, wherein the amount of said molybdenum compound is from about 0.5 to 10 moles per mole of polyamine in the polyamine derivative;
- (c) a sulfur or sulfur-yielding compound wherein the amount of said sulfur or sulfur-yielding compound is from about 0.1 to 20 moles per mole of polyamine derivative;
- and
- (d) an oxidizing agent.
