摘　　要：常压下合成了琥珀酸二异辛酯磺酸钠、琥珀酸二仲辛酯磺酸钠、琥珀酸二正辛酯磺酸钠 3种化合物。研究了催化剂种类 (浓H2 SO4、浓H3PO4、十二烷基苯磺酸 )及辛醇分子结构对酯化反应的影响及催化剂 (AOT)用量、乙醇用量、酯的结构对酯磺化反应的影响。结果表明 ,浓H2 SO4作催化剂时 ,反应速率快 ,最终转化率 1 0 0 %;相同条件下 ,正辛酯、异辛酯反应速率快于仲辛酯 ;催化剂ATO用量增加 ,磺化反应速率逐渐加快 ;乙醇用量增加 ,磺化反应速率逐渐加快 ,当加入量大于 2 0 %(质量分数 )时反应速率提高不明显。Sodium di(2 ethylhexyl)sulfosuccinate, sodium di(1 methylheptyl)sulfosuccinate and sodium dioctylsulfosuccinate were synthesized. Firstly, the effect of different catalysts on the esterification and sulfonation was investigated. The effect of catalysts such as H 2 SO 4 , H 3 PO 4 and dodecyl benzene sulfonic acid on esterification rte and conversion, and the effect of the factors such as the amount of AOT, the amount of alcohol and the structure of ester on sulfonation results were studied. The structures of products were analyzed by IR.
