摘要： 超声波辐射下三乙基苄基氯化铵相转移催化由十二醇与环氧氯丙烷合成十二烷基缩水甘油醚,产品用FT-IR进行结构表征。考察了催化剂的种类、反应物的摩尔比及其与催化剂和NaOH的摩尔比、超声波辐射功率和辐射时间等因素对产品收率的影响。结果表明,超声波辐射下,三乙基苄基氯化铵具有良好的催化活性,较佳反应条件为:十二醇0.15 mol,n(十二醇)∶n(环氧氯丙烷)∶n(三乙基苄基氯化铵)∶n(NaOH)=1∶1.15∶0.05∶1.05,甲苯15 mL,超声波辐射功率100 W下辐射45 min,此时产品的收率达到93%以上。

Abstract: Dodecyl glycidyl ether was synthesized by the reaction of epichlorohydrin and lauryl alcohol under ultrasonic irradiation with benzyltriethylammonium chloride as the phase transfer catalyst.Chemical structure of the product was characterized by FT-IR spectrum.The effects of kinds of catalyst,molar ratio of reactants,dosage of NaOH and the catalyst,ultrasonic irradiation power and time on the yield of dodecyl glycidyl ether were investigated.Results showed that benzyltriethylammonium chloride displays high catalytic activity on the reaction under ultrasonic irradiation.The optimal reaction conditions were as follows:n(lauryl alcohol)∶n(epichlorohydrin)∶n(benzyltriethylammonium chloride)∶n(NaOH)=1∶1.15∶0.05∶1.05 (based on 0.15 mol lauryl alcohol and 15 mL toluene);power of ultrasonic irradiation 100 W;time for ultrasonic irradiation 45 min.Yield of the product reaches higher than 93%.

Key words: dodecyl glycidyl ether, ultrasonic irradiation, phase transfer catalysis, synthesis
