Sodium ethylene glycol bisulfosuccinate diester was synthesized from ethylene glycol,maleic an-hydride and AEO3 by two steps esterification reactions and sulfonation reaction. The optimum reaction conditions were obtained via orthogonal experiments. The first step esterification reaction was carried out with N(ethylene glycol):N(maleic anhydride)=2. 15:1 and 2. 0% catalyst at 120 ℃ for 4 h;The sec-ond step esterification reaction was carried out with N( AEO3 ): N( ethylene glycol bismaleic acid mo-noester )=2 . 1 and 3 . 0% catalyst at 180℃ for 6 h;the sulfonation reaction was carried out with N( ethyl-ene glycol bismaleic acid diester):N( NaHSO3 )=1:3 and 1. 5% catalyst at 100 ℃ for 4 h.γCMC and CMC of product was 35. 2 mN/m and 0. 17 mmol/L,750 mg/L and the product showed high foam proper-ties.
