Abstract
Novel molybdenum complexes prepared by reacting (a) a fatty oil or acid, (b) 2-(2-aminoethyl)aminoethanol and (c) a molybdenum source are described. The molybdenum complexes impart antifriction, antioxidant, and antiwear properties to lubricating compositions and decrease fuel consumption in internal combustion engines using same.
