低泡沫环氧丙烷封端FMEE的合成以及在针织前处理中的应用《印染助剂》2023年1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PO封端的脂肪酸甲酯乙氧基化物FMEE，测试该产物的泡沫、润滑以及除油等性能并应用于针织物间歇式前处理工艺，喜赫PO封端FMEE具有优异的润滑性和低泡沫性能，能有效的减少织物浴中划痕，易于漂洗可节约用水，符合目前碳达峰碳中和的发展目标。 关键词：PO封端； FMEE；前处理；低泡沫；润滑性 The Synthesis of low-foaming FMEE containing Propylene Oxide and The application of FMEE in knitted fabric pretreatment 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, The foam, lubrication and oil removal performance of the product were tested and it was applied to the intermittent pretreatment process of knitted fabric. The PO end-capping FMEE has good lubricity, which can effectively reduce the scratches in the bath. The PO end-capping FMEE has the low-foaming ability，It is easy to rinse so that it can save water, which accords with the current development concept of Peak carbon dioxide emissions and carbon neutralization. Key words：end-capping with PO;FMEE;pretreatment;low-foaming ability;lubricity
