Abstract:With maleic anhydride,n-octanol, ethylene glycol and NaHSO3 as the main raw materials, a new Gemini surfactant--ethylene glycol succinate octyl sulfonate sodium was synthesized through monoesterifica- tion,diesterification and sulfonation. The optimum conditions were obtained by orthogonal experiments and single factor experiments. Monoesterification was carried out at 90 ℃ for 2 h,with n(n-octanol) : n(maleic anhydride) = 1.00 : 1.05. Diesterification was carried out at 100 ℃ for 3 h,with n(monoester) : n(ethylene glycol) =2.05 : 1.00 and 1.0% toluene-p-sulfonic acid. Sulfonation was carried out at 85 ℃ for 90 rain,with n(diester) : n(NaHSO3 )= 1.00 : 2.05. The structure of each compound was identified by IR. The CMC of the final product was 5.0×10^-4mol · L^-1 and its surface tension was 37.98 mN · m^-1.
Keywords:succinic sulfonate  Gemini surfactant  CMC  surface tension
