ABSTRACT:
A process for producing molybdenum oxysulfide dithiocarbamate (MoDTC) by reacting [A] an aqueous solution or suspension prepared by reacting (a) a compound having hexavalent molybdenum, with (b) an alkali hydrogensulfide or an alkali sulfide, [B] a carbon disulfide, [C] a secondary amine and [D] a mineral acid, wherein [E] a reducing agent is added and reacted at any stage, and a lubricating oil composition containing the compound obtained according to said process. MoDTC can be efficiently produced in high yields by using a hexavalent molybdenum compound as a starting material, and the produced MoDTC has low corrosive action, excellent wear characteristics and excellent lubricating properties.
