Abstract:

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.

Key words: sodium sulfosuccinate, Gemini surfactant, cmc, surfactivity
