摘　　要：在恒功率的微波作用下,以N-甲基二乙醇胺(MDEA)和氯化苄为原料,合成了甲基二羟乙基苄基氯化铵(MDBAC)。通过薄层色谱法(HLC)对产物进行了定性分析。经IR、1HNMR、13CNMR分析鉴定了产物的结构。采用响应面分析法(RSM)建立了反应转化率与各因素之间的数学关系模型,对微波合成MDBAC的工艺进行了优化。在优化条件下,反应速率是常规加热合成的60倍。测定了产物的临界胶束浓度(CMC)、表面张力、克拉夫点、熔点。Methyldihydroxyethylbenzyl ammonium chloride （MDBAC） was synthesised with MDEA and benzylchloride as raw materials under the irradiation of constant power microwave. The qualitative analysis of the product was carried out with HLC. The structure of the product was characterized with IR,^1H NMR and ^13C NMR. Through response surface methodology （RSM）, the mathematical relational model between conversion and affecting factors was established, and the microwave synthesis technique of MDBAC was optimized. Under the optimized conditions, the reaction rate was 60 times of the conventional method. The critical micelle concentration （CMC）, surface tension, Krafft point and melting point of the product were determined.
