Abstract:3 - dodecoxy1-2 - hydroxypropyl trimethyl ammonium chloride (DHTAC) is a new type of quaternary ammonium cationic surfactant, which can be used in paper making, textile, daily chemical and other fields, with sterilization, anti-static, non-toxic and so on. In this paper, DHTAC was synthesized by using dodecanol (DA) and glycidyl trimethyl ammonium chloride (GTA) under ultrasonic condition. The optimum reaction conditions of DHTAC were: n (GTA) : n (DA) = 1.2 : 1, reaction temperature of 30℃, reaction time of 1.5 h, reaction pH=9, yield of DHTAC 92.38%. The DHTAC products were analysed by elemental analysis and IR characterization.
Keywords:GTA  surfactant  DHTAC  synthesis  application
