Abstract

The invention discloses a method for preparing fatty acyl sodium methionine and a composition comprising the surfactant, and belongs to the technical field of fine chemical engineering. The technology for synthesis of the fatty acyl sodium methionine surfactant provided by the invention is characterized in that the fatty acyl sodium methionine surfactant is synthesized by taking fatty acid methyl ester from a natural grease source as a raw material, namely, fatty acyl sodium methionine and the composition comprising the surfactant are prepared from the fatty acid methyl ester and the sodium methionine in the presence of a phase transfer catalyst PEG 1500. According to the method disclosed by the invention, the raw material utilization rate is high, the yield is high, the product can be directly used without being separated and purified, the active substance content is high, the surface activity is high, the synthetic route is simple, the environment is not polluted, and therefore, the method is a clean production technology. The invention further discloses a surfactant composition comprising the fatty acyl sodium methionine.

Description

technical field [0001] The present invention relates to the method for preparing sodium fatty acyl methionine and the composition containing this surfactant, specifically in the presence of phase transfer catalyst polyethylene glycol 1500 (PEG1500), utilize fatty acid methyl ester and sodium methionine reaction synthesis The invention relates to a fatty acyl methionine sodium surfactant, which belongs to the technical field of fine chemicals. Background technique [0002] Surfactant is an important functional fine chemical, which is widely used in various industrial sectors and fields due to its special functions. Fatty acyl amino acid surfactant is a kind of protein-like mild anionic surfactant obtained by structural modification of common soaps. In addition to emulsification, washing, dispersion, foaming, penetration, and enhancement In addition to the basic properties such as solubility, compared with ordinary soap surfactants, due to the introduction of amide groups and...
