Abstract
Amides of C.sub.50-200 alkylphenoxy-substituted aliphatic carboxylic acids made by reacting a C.sub.50-200 alkylphenol with a halocarboxylic ester (e.g., butyl chloroacetate) followed by displacement of the ester group with an amide group have a much higher content of amide than a product made using a halocarboxylic acid reactant in place of the ester. The product is an effective lubricating oil dispersant.
