In this paper, firstly using natural fatty acids including lauric acid, myristic acid, palmitic acid etc. and disproportionated rosin as starting materials, the acyl reaction of starting materials with SOCl_2 respectively, and then using Schotten-Baumann condensation: on the reaction conditions of alkalescence, condensation of acylchloride with amino acid (sarcosine, glycine, alanine etc.), and then acidification, saltation. A series of anionic surfactants of N-acyl amino: sodium N-fatty acyl sarcosinate (SFS-12, SFS-14, SFS-16); sodiun N-fatty acyl glycinate(SFG-12, SFG-14, SFG-16); sodium N-fatty acyl alaninate(SFA-12, SFA-14, SFA-16)and sodium N-disproportionated rosinoyl aminatewere prepared. During the preparation of N-acylamino acid, the reaction conditions of acylchloride with amino acid condensation were identified by optimizing the synthetic conditions of N-lauroyl sarcosine: mol ratio of amino acid to acylchloride 2:1, reaction taken place in a solvent composed by acetone/water 2:1, acylchloride and 20% NaOH were slowly added to the reaction mixture at the same time while maintaining the pH at 9~10, after completion of adding maintaining reacting for 2.5h at 25℃.
