摘　　要：以十六碳脂肪酸为原料,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PO封端的脂肪酸甲酯乙氧基化物FMEE。将FMEE进一步与氯磺酸反应得到磺化盐FMES,测试产物FMEE和FMES的泡沫、HLB值、乳化力、分散力等性能。将非离子PO嵌段FMEE与阴离子磺酸盐FMES作为主要退浆剂,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等,用于染厂实际的坯布前处理生产,织物退浆率高,并能有效地防止浆料对织物的反沾。With aluminum oxide and barium oxide as binary catalysts,hexadecyl fatty acid is polymerized with ethylene oxide,and then terminated with propylene oxide.Finally,terminal methyl is introduced through meth⁃ylation reaction to obtain PO terminated fatty acid methyl ester ethoxylate FMEE.FMEE is further reacted with chlorosulfonic acid to obtain sulfonated salt FMES.The foam,HLB value,emulsifying power,dispersing power and other properties of FMEE and FMES are tested.Nonionic PO block FMEE and anionic sulfonate FMES are used as the main desizing agents,combined with penetrant sodium primary alkyl sulfonate PAS-80 and phos⁃phorus free chelator ethylenediamine di-o-phenylacetate sodium EDDHA-Na.They are used in the grey fabric pretreatment production in the dyehouse.The desizing rate of the fabric is high,and the anti staining of the size to the fabric can be effectively prevented.
