摘　　要：以脂肪醇醚(AEO9)、氯乙酸和氢氧化钠为原料,通过羧甲基化法合成脂肪醇醚羧酸钠盐。利用红外光谱对产品进行结构分析,研究了反应物摩尔比、反应温度与反应时间等因素对产品阴离子活性含量的影响。得出最佳反应条件为:n(AEO9)︰n(ClCH2COOH)︰n(NaOH)=1.0︰1.5︰2.0,反应温度T=55℃,反应时间t=3h。在此条件下反应,产品的阴离子活性含量高达74.93%。Sodium fatty alcohol polyoxyethylene ether carboxylate was synthesized from AEO9,Chloroaceticacid and Sodium hydroxide by carboxymethyl method.The structure of product was characterized by IR.The influences of the factors,such as reactant molar ratio,reaction temperature,reaction time on content of anion surface active agent of product are studied.The optimum reaction conditions are as follows:n(AEO9)︰ n(ClCH2COOH)︰ n(NaOH)=1.0︰ 1.5︰ 2.0,reaction temperature was 55℃,reaction time was 3 h,and under these conditions,the anion activity content of the product was up to 74.93%.
