MOLYBDENUM-CONTAINING LUBRICATING ADDITIVE COMPOSITION AND ITS PRODUCTION METHOD AND USE

摘要

PPROBLEM TO BE SOLVED: To provide an improved method for producing an organic molybdenum composition having a high molybdenum content which is very suited in use as a lubricating additive. PSOLUTION: The method comprises reacting a fatty oil with a diamine, and then reacting the resulting product with a molybdenum source. This method has no need to use a volatile organic solvent in order to promote entrapment of molybdenum, and produces an organic molybdenum composition having a high molybdenum content. In addition, this method can be carried out in the absence of a sulfur-containing reactant and in the absence of a phosphorus- containing reactant. PCOPYRIGHT: (C)2003,JPO
