Abstract: A kind of novel betaine type amphoteric surfactant was synthesized using tetradecylamine and pentaerythritol as the starting material. The influence factors of the synthesis process were studied.The optimal condition of the synthesis was gained. The results have show that the reaction time and mole ratio (Dimethyl tetradecyl tertiary/ Intermediate) were 16h and 1.2/1 at 120°C.The structure of myristyl sulpho betaine type amphoteric surfactant was identified by FTIR.Then it was performed the surface tension tests to determine the critical micelle concentration (cmc).

Abstract: A kind of novel betaine type amphoteric surfactant was synthesized using tetradecylamine and pentaerythritol as the starting material. The structure of bismyristyl bisulpho betaine type amphoteric surfactant was identified by FTIR.The influence factors of the synthesis process were studied.The optimal condition of the synthesis was gained. The results have show that the reaction time and mole ratio (Intermediate / Dimethyl tetradecyl tertiary) were 18 h and 0.5/1 at 135°C. Then it was performed the surface tension tests to determine the critical micelle concentration(cmc).
