Summary: | The invention aims at solving the technical problem that during synthesis of N-fatty acyl glutamic acid salt, when a solvent contains water, hydrolysis of fatty acyl chloride is severe. According to the technical scheme, a synthesis method of N-fatty acyl glutamic acid alkali metal salt comprises the step that an alkali mixture 1 with glutamic acid alkali metal salt, an amidation reaction additiveand a solvent is obtained in a reactor; the amidation reaction additive comprises N-fatty acyl glutamic acid alkali metal salt; the solvent comprises water; through stirring, the fatty acyl chlorideis added into the reactor, the fatty acyl chloride and the glutamic acid alkali metal salt react to generate the N-fatty acyl glutamic acid alkali metal salt in the reactor, and the pH of contents ofthe reactor keeps alkali in the reaction process.
