Abstract
Long chain N-acyl amino acids have good surface activities and the application of these surfactants have been expanded. Long chain N-acyl amino acids were usualy prepared by the Schotten-Baumann method but this method was not suitable enough for an industrial detergent production. In this report, the acylation of amino acids by long chain fatty acid-sulfonic acid mixed anhydride (FSA) was described. FSA obtained from long chain fatty acid and sulfur trioxide was unstable and the acylation of amino acids by this FSA resulted in low yields. However, the triethylamine salt of long chain fatty acid-sulfonic acid mixed anhydride (FSAT) obtained by the reaction of long chain fatty acid with sulfur trioxide in the presence of triethylamine was more stable than FSA, and the FSAT was a good acylation reagent. The structure of FSAT was also investigated.
