Paragraph 0028, (2020/04/22)
The invention discloses a method for synthesizing a fatty acyl amino acid surfactant by using a direct method. The method comprises the following steps: (1) adding fatty acid, methylamine and hydroxyethyl sulfonate into a reactor; (2) closing the reactor, and slowly heating to 150-300 DEG C; (3) carrying out a heat preservation reaction for 2-10 hours; (4) distilling to remove unreacted methylamine; and (5) treating to obtain a finished product. According to the invention, fatty acid, methylamine and sodium isethionate are selected to be subjected to a direct reaction, impurities such as chlorine ions and the like are not introduced in the process, and the target product is obtained through the direct reaction, so that the purification steps such as acidification, salification and the likeare omitted, and the use and discharge of salt-containing wastewater or an organic solvent are reduced; and the operation is convenient, the industrial production is easy to realize, the product formof the prepared product can also be changed according to actual requirements, and the cost advantage and the application convenience advantage of the product are improved.
