  • Organic molybdenum complexes
    Patent number: 4889647
    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.
