ABSTRACT:
The invention provides molybdenum-containing complexes prepared by reacting a carboxylic acid or metal salt thereof, an amine and a source of cationic molybdenum, wherein the ratio of the number of equivalents of acid groups to the number of moles of molybdenum (eq:mol) is in the range from 1:10 to 10:1, and the ratio of the number of equivalents of acid groups to the number of moles of amine (eq:mol) is in the range from 20:1 to 1:10; a process for their preparation; lubricating oil compositions containing them; and their use as friction-reducing additives.
