A SURFACTANT AND THE CHEMICAL SYNTHETIC METHOD THEREOF

摘要

A surfactant and its chemical synthetic method which consists of the following steps: making lipopeptide produced by germ react with diamine or diol material in the presence of catalyst and solvent, then collecting the surfactant from the reaction product. The general formula of the surfactant is M-NH(CH₂)_nNH-M or M-O(CH₂)_nO-M, which is made of two molecules of lipopetide with one connecting radical. The surfactant can be applied to the industries of oil, cosmetic, foodstuff, medicament and so on as wetting agent, foaming agent, bacteriostatic agent, viscosity increaser, emulsifying agent, inhibitor and soon.
