3-chlorine-2-hydroxypropyl triethyl ammonium chloride (CTA) was synthesized with epichlorohydrin

triethylamine muriate as raw materials under the irradiation of constant power microwave.Analysis by TLC and chemical titration indicated the purity of the product above 99.0% after the crystallization in the mixture of acetoacetate and ethanol.The structure of CTA was identified by IR and NMR.The factors which influenced the yield of CTA were investigated in terms of microwave power

reaction time

temperature and mole ratio of raw materials.Experimental results showed that the yield of CTA improved by 16.58% and the reaction time was 340 min shorter than the traditional method under the following reaction conditions: microwave power 300 W

50℃

mole ratio of raw materials 1.15∶1

reaction time 20 min.Finally the CMC

surface tension

Krafft point and melting point of the CTA were determined.
