Problems solved by technology

[0005] This process needs to be treated because of the HCl generated by the hydrolysis of acid chlorides, and the operation process is relatively complicated, and the raw material PCl 3 It is highly irritating to the human body, and there is an environmental pollution problem, and the cost of using fatty acid chlorides as raw materials is high, so that the products produced by this process are subject to certain restrictions in application.

Abstract

The invention discloses a method for preparing N-fatty acyl amino acid surfactants from oily esters, belonging to the technical field of organic compound synthesis. The technology for synthesizing N-fatty acyl amino acid surfactants provided by the present invention uses grease instead of acid chlorides to synthesize N-fatty acyl amino acid surfactants, and utilizes grease and amino acid sodium to react under catalyst conditions to generate N-fatty acyl amino acid sodium. It has the advantages of excellent product surface activity, simple synthesis route and no environmental pollution, and conforms to the principle of green chemistry.

Description

technical field [0001] The invention relates to the preparation of N-fatty acyl amino acid surfactants, in particular to the preparation of N-fatty acyl amino acid surfactants by using oily esters, and belongs to the technical field of organic compound synthesis. Background technique [0002] Compared with ordinary soap surfactants, N-fatty acyl amino acid surfactants have more excellent resistance to hard water, low irritation, low toxicity, softness, corrosion inhibition and rust resistance due to the addition of amide groups and amino acid moieties. , good biodegradability and good affinity to the human body, etc., and has good compatibility with other surfactants, hard water resistance, affinity, and stability. It can be used in detergents, medicines, antibacterial agents, and waste water. treatment and cosmetic fields. As people pay more and more attention to the safety and mildness of surfactant products and the improvement of environmental protection requirements, th...
