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 relates to a method for preparing an N-fatty acyl amino acid type surfactant by fat and belongs to the technical field of synthesis of organic compounds. In a technology for synthesizing the N-fatty acyl amino acid type surfactant, the fat replaces acyl chloride, so that the N-fatty acyl amino acid type surfactant can be synthesized; the fat and amino acid sodium react under a catalytic condition to generate N-fatty acyl amino acid sodium; therefore, the method has the advantages of high product surface activity, simple synthesis line, environment friendliness and the like; and the green chemistry rule can be met.

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...
