Abstract
A processes for preparing highly sulfurized molybdenum oxysulfide dithiocarbamates (Mo DTCs) by reacting: [A] a tertiary amine, [B] a hexavalent molybdenum compound, [C] carbon disulfide, [D] water, and [E] a secondary amine are disclosed. The Mo DTCs can be efficiently produced with high sulfur contents and in high yields with low corrosive action and excellent friction properties. The produced Mo DTCs can be used in either grease or lubricating oils as friction modifiers, antiwear agents, extreme pressure agents and antioxidants.
