Abstract:
A process for the preparation of an amino carboxylic acid, a salt of the amino carboxylic acid, or an ester of the amino carboxylic acid by carboxymethylation of a carbamoyl compound, the process comprisingforming a reaction mixture by combining the carbamoyl compound, a carboxymethylation catalyst precursor, carbon monoxide, hydrogen, water, and an aldehyde, wherein the carbamoyl compound and the carboxymethylation catalyst precursor are combined before the water and the aldehyde are introduced into the reaction mixture; andreacting the components of the reaction mixture to generate a product mixture containing an N-acyl amino carboxylic acid reaction product and a catalyst reaction product.
