摘要
在碱催化下通过聚乙二醇单甲醚（ＰＧＭＥ）和脂肪酸甲酯的酯交换反应合成了ＰＧＭＥ脂肪 酸酯。在酯和醇醚摩尔比为１：１．２．催化剂质量分数为０５％、反应温度１２０℃、反应时间６．５ｈ条 件下，对脂肪酸甲酯的摩尔收率可达９０％。用ＩＲ、^（１３）ＣＮＭＲ对产物结构进行了确证，同时对产物 的表面物性进行了测试。
Polyethylene glycol monomethyl ether(PGME) fatty arid esters were Preped fain methyl fatty acid ester and PGME in the presence of sodium methoxide as catalyst. When a molar ratio of ester to alcohol ether was l: 1. 2, 0. 5% (w) catalyst was used, the mixture was stirred for 6.5h at 120℃, the molar yield of the products based on methyl fatty acid ester can reach 90%. Their structures were confirmed by IR and ^(13)CNMR. The surface active properties of the products were also determined.
