摘要
以正庚醇为原料 ,通过格尔贝特 (Guerbet)反应合成的Guerbet十四醇 (2 -戊基 -壬醇 ,C14 GA) ,经氯磺酸磺化 ,再用氢氧化钠中和 ,得到阴离子表面活性剂Guerbet十四醇硫酸盐 (C14 GAS)。用IR、NMR和元素分析测定了C14 GA和阴离子表面活性剂C14 GAS的结构 ,利用表面张力法测定了不同条件下的此种表面活性剂水溶液的cmc 。
Guerbet alcohol 2-pentyl,nonyl alcohol(C 14 GA) sy nthesized from 1-heptanol by Guerbet reaction was esterified by chlorosulfonic a cid,and further neutralized by sodium hydroxide,thus,the anionic surfactant sodi um Guerbet tetradecyl sulfate(C 14 GAS)was obtained.The structures of C 1 4 GA and C 14 GAS were identified by IR?NMR and element analysis.The criti cal micelle concentration(cmc)was determined by surface tension method,and other thermodynamic properties of this surfactant were also studied.
