摘　　要：以葡萄糖和氯乙酰氯为原料,合成了中间体葡萄糖氯乙酸酯(GCAE),再与十二烷基二甲基叔胺在正丙醇和水的混合溶液中制备了产物葡萄糖酯基季铵盐(CAGE)。通过傅里叶红外光谱(FTIR)与核磁共振氢谱(1HNMR)对中间体及产物进行了结构表征,并对产物与十二烷基硫酸钠(K12)复配体系的稳定性、表面活性、泡沫性能和润湿性能进行了测定。结果表明:产物具有良好的表面活性(γcmc=24.5 mN·m-1);与K12的复配稳定性好,表现出良好的协同增效作用,当n(CAGE)∶n(K12)=0.5∶1时,复配体系的临界胶束浓度(cmc)可低至0.158 mmol.L-1,大大低于单一组分的cmc,表面张力与CAGE的相当,起泡性和泡沫稳定性也好于单一组分,润湿性比K12略差,比CAGE好。Intermediate glucose chloroacetate （GCAE） was prepared with glucose and chloroacetyl chloride as starting materials. Then the intermediate was reacted with dodecyl dimethyl tertiary amine in solvent composed of n -propanol aqueous solution to produce glucose ester quaternary ammonium salt （CAGE）. Chemical structure of the intermediate and the product was characterized by FFIR and 1HNMR. Stability, surface activity ,foaming properties and wetting power were investigated for blend systems composed of CAGE and sodium dodecyl sulfate （K12）. It was found that γcmc of CAGE is 24.5 mN · m-1 ,and blend systems of CAGE and K12 shows a good stability and a strong synergic effect. When n （ CAGE ） ： n （ K12 ） = 0. 5 ： 1, critical micelle concentration （cmc） of blend systems is 0. 158 mmol · L-1 ,which is much lower than that of any single component, while the surface tension is equivalent with that of the CAGE. Foaming power and foam stability of the blend systems are better than that of any single component;while wetting power of the blend systems is a little lower than that of K12, but better than that of the CAGE.
