摘　　要：醇醚和酚醚羧酸盐是一种性能温和、无毒、生物降解性表面活性剂。报道了以醇醚 (酚醚 )、一氯乙酸和氢氧化钠为原料通过减压除水法合成醇醚 (酚醚 )羧酸盐的方法和限制一氯乙酸钠的情况下合成反应的最佳条件。Ethoxylated carboxylates are excellent surfactants. Their synthetic method from ethoxylated alcohols, chlorocetic acid and sodium hydroxide under reduced pressure is described. The optimum technical conditions for carboxymethylation were studied.
