摘 要：以十六碳脂肪酸为起始原料，采用无水的三氧化二铝和氧化钡为二元催化剂，先与环氧乙烷发生聚合反应，再用环氧丙烷封端，最后通过甲基化反应引入末端甲基，得到的喜赫PO封端的脂肪酸甲酯乙氧基化物FMEE，将FMEE进一步与了氯磺酸反应得到喜赫磺化盐FMES，测试产物喜赫FMEE和FMES的泡沫、HLB值、乳化力、分散力等性能，并通过单因素试验确定了FMEE和FMES用量为2:1有最佳的除蜡效果，将喜赫非离子PO嵌段FMEE与喜赫阴离子磺酸盐FMES作为除蜡水的主体表面活性剂，并复配喜赫渗透剂伯烷基磺酸钠PAS-80、喜赫无磷螯合剂乙二胺二邻苯基乙酸钠EDDHA-Na以及其它助剂，最终得到两个除蜡水的配方，分别用于工厂实际的金属表面生产，除蜡效果均符合工厂的要求。

Abstract：Hexadecane fatty acid was polymerized with ethylene oxide and propylene oxide in condition of anhydrous AL2O3 and BaO as binary catalysts，methyl was introduced through methylation reaction, then FMEE was reacted with chlorosulfonic acid to obtain FMES, and the foam, HLB value, emulsifying power, dispersing power of FMEE and FMES were tested, the proportion of FMEE and FMES was 2:1 through the single factor test, which has the best de-waxing effect. The non-ionic po blocked FMEE and the anionic FMES were used as the main surfactant of de-waxing agent, two formulas of de-waxing agent were obtained, which were used in the actual metal surface production of the plant respectively. The two formulas were composed with the penetrating agent PAS-80, the phosphate-free chelating agent EDDHA-Na and other auxiliary agents, the wax removal effect is in line with the requirements of the plant.
Key words：end-capping with PO; FMEE; FMES; low-foaming ability; de-waxing agent
