Problems solved by technology

However, the disadvantage of the method described in ZL 200110162138.8 is that the catalyst used is metal oxide and carrier 4A zeolite, which is a heterogeneous catalyst with poor solubility in water, so there is still a possibility of improvement. In addition, the obtained surfactant properties still need further improvement

Abstract

The invention discloses a method for preparing grease acyl sodium leucine and a surface active agent composition containing the grease acyl sodium leucine in a phase-transfer catalysis way, and belongs to the technical field of fine chemical engineering. According to a technology provided by the invention for synthesizing a grease acryl sodium leucine-type surface active agent, grease and sodium leucine react in the existence of a phase-transfer catalyst PEG800 to generate the grease acryl sodium leucine. The method is high in yield and high in raw material utilization rate, the phase-transfer catalyst PEG800 is prepared by adopting matrix raw materials and active components such as a washing agent, cosmetics and medicines and plays a role in adjusting viscosity, stabilizing, moistening and the like, a product does not need to be separated and can be directly used, the product is a composition of different carbon-chain acryl sodium leucine homologous series and conforms to a surface active agent compounding principle, a synergistic effect can be realized, the content of active matters is high, the surface activity is high, the synthesis route is simple, no pollutant is produced, and the preparation method is environmentally friendly. The invention also relates to the surface active agent composition containing the grease acryl sodium leucine.

Description

technical field [0001] The present invention relates to the preparation method of fatty acid acyl leucine sodium and the composition comprising this surfactant, specifically in the presence of phase transfer catalyst polyethylene glycol 800 (PEG800), using grease and sodium leucine The invention relates to the reaction synthesis of fatty acid acyl leucine sodium surfactant, which belongs to the technical field of fine chemical industry. 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 amino...
