| Abstract: | Lauric acid ester quaternary ammonium salt cationic surfactant 2-hydroxyl-3-cetyl poloxy cetyl dimethyl ammonium dichloride was synthesized by quaternarization of dedocyldimethylamine in acetone with epichlorohydrine(EPIC) and HDAC.Experiment condition was optimized by the method of orthogonal experiment.The yield can achieve 85%.The critical micelle concentration of CMC is 0.035 mmol/L,and the surface tension of γCMC is 44.95 mN/m.This surfactant shows good wetting and biodegradable property. |
