Process for Preparation of Low Molecular Weight Molybdenum Succinimide Complexes

Abstract

Disclosed is a product prepared by the 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: wherein R is an about C 12 to C 30 alkyl or alkenyl group, R′ is a straight or branched-chain alkylene group having 2 to 3 carbon atoms, x is 1 to 11, and y is 1 to 10, with an α,β-unsaturated mono-carboxylic acid or carboxylic acid ester, in a charge mole ratio of the α,β-unsaturated mono-carboxylic acid or carboxylic acid ester to the succinimide of formula I or formula II or mixtures thereof of about 0.1:1 to about 6:1, 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.

What is claimed is: 
     
         1 . The product prepared by the 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:   
       
         
           
           
               
               
           
         
       
       wherein R is an about C 12  to C 30  alkyl or alkenyl group, R′ is a straight or branched-chain alkylene group having 2 to 3 carbon atoms, x is 1 to 11, and y is 1 to 10, with an α,β-unsaturated mono-carboxylic acid or carboxylic acid ester, in a charge mole ratio of the α,β-unsaturated mono-carboxylic acid or carboxylic acid ester to the succinimide of formula I or formula II or mixtures thereof of about 0.1:1 to about 6:1, 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.
