摘　　要：以2-十二酮、丙三醇和丙磺酸内酯为原料,通过两步法合成出一种新型的缩醛型可降解表面活性剂——3-[(2-癸基-2-甲基-1,3-二氧杂环戊烷-4)-甲氧基]丙烷-1-磺酸钠盐。产物结构经红外光谱和核磁共振氢谱分析表征,数据结果显示产品为目标产物。通过利用电化学方法测定产物的电导率,分析产物水溶液物理性质与浓度关系,测定表面活性剂的临界胶束浓度接近8.0×10-3mol/L。A new acetyl cleavable surfactant sodium 3-[ （2-deeyl-2-methyl-1,3-dioxolan-4-yl ） methoxyl ] propane-1-sulfonate was synthe- sized from the starting material dodecan-2-one and glycerol. The structure of the resulting product was characterized by IR and ^1H NMR.The results showed that the product was the resulting compound. The conductance of the product was edtermined by electrochemistry method. The relation between product＇s physical property and concentration was analyzed. Critical micelle concentration of the surfactant was 8.0 ×10^-3 mo]/L.
