ABSTRACT:
Amino-functional compounds are economically prepared by reacting maleic anhydride with alcohols to form a maleate or fumarate "half-ester" which is combined with certain amines, most preferably aspartate or glutamate, under conditions selected to avoid hydrolysis. At low molecular weights, the compounds herein are useful detergency builders; at progressively higher molecular weights within a specific range, combined builder/dispersant and typical dispersant properties emerge. Processes for preparing the compounds and useful detergent compositions containing them are described.
