PREPARATION OF ALKALI METAL ACYL AMINO ACIDS

摘要

A process of preparing alkali metal N-acyl amino acids, especially sodium Nacyl sarcosinates. The process of the invention eliminates the use of phosphorus trichloride or thionyl chloride and carboxylic acid chlorides. The process involves reacting the alkali metal N-acyl amino acid directly with a fatty acid at elevated temperatures with constant removal of water generated in the reaction.
