Sodium di(2-ethylhexyl) sulfosuccinate was prepared in the condition of purging with N_2 and catalyzed by paratoluenesulfonic acid.Effects of some factors such as reaction temperature,vacuum and molar ratio of 2-ethyl hexanol vs maleic anhydride etc.on esterification were studied.When esterification reaction was continue over 2h,the results indicated that the esterification product was colorless and transparent and the esterification conversion was up to 99.6% at the condition of 130℃,29.33kPa… CONTINUE READING
