IMPROVED PROCESS FOR PREPARATION OF LOW MOLECULAR WEIGHT MOLYBDENUM SUCCINIMIDE COMPLEXES

摘要

Disclosed is a process for preparing a molybdated succinimide complex, the process comprising: (a) reacting an alkyl or alkenyl succinimide of a polyamine of formula (I) or formula (II) or mixtures thereof: with an a,ß-unsaturated mono-carboxylic acid or carboxylic acid ester, and wherein the reaction temperature is no greater than about 135°C; and (b) reacting the succinimide product of step (a) with an acidic molybdenum compound to provide the molybdated succinimide complex, wherein the molybdated succinimide complex prepared is a liquid at room temperature.
