Abstract
New molbdenum complexes prepared by reacting (a) a fatty oil, (b) diethanolamine and (c) a molybdenum source are described. The molybdenum complexes impart antifriction and antiwear properties to lubricating compositions and decrease fuel consumption in internal combustion engine using same.
Claims4
An organic molybdenum complex prepared by reacting (a) about 1.0 mole of fatty oil having 12 or more carbon atoms, (b) about 1.0 to 2.5 moles diethanolamine and (c) a molybdenum source sufficient to yield about 0.1 to 6.0 percent of molybdenum based on the weight of the complex, the reaction being carried out at about 70.degree. to 160.degree. C.
A lubricating composition comprising a major amount of a lubricating oil and about 0.01 to 5.0 percent of an organic molybdenum complex prepared by reacting (a) about 1.0 mole of fatty oil having 12 or more carbon atoms, (b) about 1.0 to 2.5 moles diethanolamine and (c) a molybdenum source sufficient to yield about 0.1 to 6.0 percent molybdenum based on the weight of the complex, the reaction being carried out at about 70.degree. to 160.degree. C.
A method of reducing fuel consumption in an internal combustion engine which comprises lubricating said engine with a lubricating composition comprising a major amount of a lubricating oil and about 0.01 to 5.0 percent of an organic molybdenum complex prepared by reacting (a) about 1.0 mole of fatty oil having 12 or more carbon atoms, (b) about 1.0 to 2.5 moles diethanolamine and (c) a molybdenum source sufficient to yield about 0.1 to 6.0 percent molybdenum based on the weight of the complex, the reaction being carried out at about 70.degree. to 100.degree. C.
