琥珀酸酯磺酸盐Gemini表面活性剂的合成及表面活性

Synthesis and Surface Activities of Gemini Sodium Sulfosuccinate

以1-十二醇、1-十四醇、1-十六醇、1-十八醇、马来酸酐和乙二醇为主要原料,合成4种琥珀酸酯磺酸盐Gemini表面活性剂;借助红外光谱和核磁共振氢谱对所合成的化合物结构进行了表征。4种表面活性剂均具有较低的临界胶束浓度,较强的乳化性能以及较好的泡沫性能。进一步讨论了4种表面活性剂结构与性能的关系。

Four different sodium sulfosuccinates were synthesized using 1-dodecanol,1-tetradecanol,1-hexadecanol,1-octadecanol,maleic anhydride and ethylene glycol as starting materials.The structures of the target compounds were identified by IR and 1H NMR.The results of surface tensions,foaming abilities and emulsifiability measuring show that every compound has lower critical micelle concentration（cmc）,stronger emulsifying and better foaming ability.In addition,the structures and the performance relations of the four compounds were discussed.
