摘要: 以脂肪醇(辛醇、癸醇和十二醇)、脂肪醇聚氧乙烯醚(AEO7)和丙烯酸叔丁酯等为原料,经过加成反应和皂化反应合成了4种醇醚丙酸盐,用FTIR,1HNMR及ESI-MS对产物进行了结构表征。优化后的加成反应工艺条件为:n(脂肪醇或醇醚):n(丙烯酸叔丁酯):n(甲醇钠)=1:3:0.02,50 ℃下反应6 h。对4种醇醚丙酸盐的表面活性测定表明:均表现出了优良的表面活性;亲水基相同时,其临界胶束浓度(cmc)和相应的表面张力(γcmc)及分子最小横截面积(Amin)均随碳链的增长而逐渐减小,而饱和吸附量(Γmax)和吸附效率(pc20)则随碳链的增长逐渐增大;分子中引入乙氧基后,其cmc,γcmc和Amin增大,而Γmax和pc20减小。

Abstract: Four kinds of fatty alcohol ether propionate were synthesized via addition and saponification with fatty alcohol (octanol,decanol and dodecanol),fatty alcohol polyoxyethylene ether (AEO7) and tert-butyl acrylate as raw materials.Structure of the products was characterized by FTIR,1HNMR and ESI-MS methods.The addition reaction parameters were optimized via a series of experiments as follows:n(fatty alcohol (AEO7)):n(tert-butyl-acrylate):n(sodium methoxide)=1:3:0.02;reaction temperature,50 ℃;reaction time,6 h.The products show good surface activity.With increasing of the carbon chain length,their cmc,γcmc and Amin decreases while Γmax and pc20 increases.However,the results were reversed as the fatty alcohol molecules are ethoxylated.

Key words: alcohol ether propionate, fatty alcohol, fatty alcohol polyoxyethylene ether, tert-butyl acrylate, synthesis, surface activity
