| Abstract: | A new surfactant disodium N-dodecylmonoamido sulfosuccinate (SDAS) was synthesised by amidation of maleic anhydride with dodecyl amine in a selected hydrocarbon solvent and then by sulfonation with Na 2SO 3. The optimum reaction conditions were studied by orthogonal experiments, the results were as follows: anhydride/dodecylamine (molar ratio) =1∶1.14, amidation temperature 60 ℃, amidation time 15 min; anhydride/Na 2SO 3 (molar ratio)=1∶1.10, sulfonation temperature 70 ℃ sulfonation time 2 h. The yield was more than 93%. The application properties of SDAS were measured and discussed. |
