摘要
以脂肪醇为原料 ,通过Williamson合成法合成了聚氧乙烯醚加成数n =2、 3、 4的均质醇聚氧乙烯醚 ,并利用羧甲基化法合成了聚氧乙烯醚加成数n =2、 3、 4的均质脂肪醇聚氧乙烯醚乙酸钠。经减压蒸馏提纯 ,薄层色谱显示均为单一斑点。综合表面活性测试结果表明 ,当脂肪基的碳链长度相同时 ,随着聚氧乙烯醚加成数的增加 ,均质脂肪醇聚氧乙烯醚羧酸钠盐的表面活性增加 :当聚氧乙烯醚加成数相同时 ,随着脂肪基的碳链长度的增加 ,均质脂肪醇聚氧乙烯醚羧酸钠盐的表面活性增加。
A series of homogeneous polyoxyethylene ethers of dodecanol,tetradecanol and octadecanol,and their carboxylates were synthesized,and their properties such as cmc,γ cmc ,foaming.and detergency were determined.When the carbon chain length of aliphatic group is same,their surface activities are boosted as the EO number of polyetheroxy ether increases:when the EO numbers are same,their surface activities ane boosted while the carbon chain length increases.
