Abstract
Sodium hydrogen cis-epoxysuccinate was synthesized in an aqueous solution containing 75% dilute alcohol and over sodium tungstate dihydrate catalyst. Effects of reaction time, reaction temperature, catalyst dosage and pH of reaction solution on yield of sodium hydrogen cis-epoxysuccinate were studied. The optimal reactant condition was obtained though single factor and orthogonal experiments: reacted for 2.0 h at 60℃ with 0.825g(0.0025mol) of catalyst and ph=3.5, the top yield was 71.46%. The molecular structure was calculated by using ab initio molecular orbital method at HF/6-31G* level.
