摘　　要：以十六碳脂肪酸为起始原料,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磺化盐FMES,并通过单因素试验确定了FMEE和FMES用量为2∶1有最佳的脱脂效果,将FMEE与FMES作为脱脂剂的主体表面活性剂,并复配渗透剂伯烷基磺酸钠PAS-80、无磷螯合剂乙二胺二邻苯基乙酸钠EDDHA-Na以及其它助剂,并用于工厂实际的金属表面生产,脱脂效果均符合工厂的要求。Hexadecane fatty acid was polymerized with ethylene oxide and propylene oxide,methyl was introduced through methylation reaction,then FMEE was reacted with chlorosulfonic acid to obtain FMES,the proportion of FMEE and FMES was 2∶1 through the single factor test,which had the best degreasing effect.The non-ionic po blocked FMEE and the anionic FMES were used as the main surfactant of degreasing agent,two formulas of degreasing 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 grease removal effect was in line with the requirements of the plant.
