FMEE与FMES的合成以及在退浆剂配方中的应用《印染》2022年7期 王琛 上海喜赫精细化工有限公司，上海，201620 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，将喜赫FMEE进一步与氯磺酸反应得到磺化盐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喜赫FMEE和FMES用量为1:2有最佳的退浆效果，将喜赫非离子PO嵌段FMEE与喜赫阴离子磺酸盐FMES作为退浆剂的主体表面活性剂，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，最终得到退浆剂的配方，分别用于染厂实际的坯布前处理生产，织物退浆率高，并能有效的防止浆料对织物的反沾。 关键词：PO封端；喜赫FMEE；喜赫FMES；低泡沫；退浆剂 The synthesis of FMEE and FMES and the application in formulation of desizing agent WANG Chen Shanghai Xihe Fine Chemical Co. ,Ltd, Shanghai ,201620,China 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 1:2 through the single factor test, which has the best desizing effect. The non-ionic po blocked FMEE and the anionic FMES were used as the main surfactant of desizing agent, two formulas of desizing agent were obtained, which were used in the pretreatment process of the plant respectively. The three formulas were composed with the penetrating agent PAS-80, the phosphate-free chelating agent EDDHA-Na and other auxiliary agents. These three kinds desizing agents are used in pre-treatment process, which can get excellent desizing and ant-staining rate.
