Abstract: Amphiphilic anionic surfactant is produced through following measure: Take stearic acid as main raw material, and then make sulfornation by battery acid at 85℃. reaction time is 6 hour. then the product is purified with water/acetone, in the end, reacted with NaOH again. Infrared spectrum preliminarily makes sure its structure.This experiment shows that target′s aqueous solutions are of lower CMC and γ CMC than SDS′s and higher surface activity, in the meantime, latherability and foam stability.

Key words: stearic acid, sulfonation, critical micelle concentration, latherability, foam stability
