WIPO Patent Application WO/2023/093560
Kind Code:
A1
Abstract:
The present invention discloses a method for preparing an N-fatty acyl amino acid surfactant by means of high-temperature melting and direct condensation. The method of the present invention comprises: mixing a fatty acid, a catalyst and an amino acid, heating same to a molten state for a reaction, and then subjecting same to dehydration condensation to obtain the N-fatty acyl amino acid surfactant. The method avoids the use of acyl chloride as in the traditional method; the resulting product does not contain any salt; and the method has the advantages of a simple operation, an excellent product performance, environmental friendliness, etc.
