Abstract
A process of preparing alkali metal N-acyl amino acids, especially sodium N-acyl 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.
Claims9
A process for producing alkali metal N-acyl amino acid, comprising reacting a fatty acid having the formula RCOOH wherein R is a C.sub.1 or higher hydrocarbyl substituent with (a) an alkali metal amino acid in which the amino group is substituted with at least one hydrogen atom, and (b) the acid of said alkali metal amino acid.
