摘　　要：采用间接酯化法,以柠檬酸和乙酸酐为原料,先合成柠檬酸酐,后与醇醚糖苷(含有未反应的脂肪醇醚)反应,合成了醇醚糖苷柠檬酸单酯,再用NaOH溶液、饱和Ca(OH)2水溶液和Mg(OH)2乳浊液中和制得醇醚糖苷柠檬酸单酯二钠盐(MAEG-EC-Na)、醇醚糖苷柠檬酸单酯钙盐(MAEG-EC-Ca)和醇醚糖苷柠檬酸单酯镁盐(MAEG-EC-Mg),对产物的物化性能进行了测定。结果表明,上述3种产品的γcmc变化范围均很小,而柠檬酸单酯二钠盐的cmc最小,柠檬酸单酯盐起泡性能、泡沫稳定性的顺序为MAEG-EC-Mg>MAEG-EC-Ca>MAEG-EC-Na。Through indirect esterification,citric acid anhydride was synthesized with citric acid and acetic anhydride as raw materials, the citrate monoesters were prepared with synthetic citric acid anhydride and ethoxylated fatty alcohols glucoside （containing excess ethoxylated fatty alcohols） ,and then neutralization with NaOH ,Ca （OH）2 and Mg （OH）2 obtained the citrate monoesters disodium salt of ethoxylated fatty alcohols glueoside （MAEG-EC-Na）, citrate monoesters calcium salt of ethoxylated fatty alcohols glucoside （MAEG-EC-Ca） and citrate monoesters magnesium salt of ethoxylated fatty alcohols glucoside （ MAEG- EC-Mg）. The physicochemical properties of the products were measured. Results showed that the γcmc range of the three products are very small, and the cmc of citric acid monoester disodium salt of ethoxylated fatty alcohols glucoside is minimum. The order of foaming ability and foam stability of citric acid mo- noester salt is MAEG-EC-Mg 〉 MAEG-EC-Ca 〉 MAEG-EC-Na.
