Abstract

Epoxysuccinic acid (ESA) was synthesized using maleic anhydride (MA) as the raw material, NaOH as the initiator and 30% H2O2 as the oxidizing agent, and three kinds of agents as catalysts, and the effects of different catalysts on the yield of ESA were investigated. The results showed that the optimal composite catalyst was composed of sodium tungstate Na2WO4 and sodium molybdate Na2MoO4 . The optimal synthetic conditions of ESA were as follows: the molar ratio of MA to NaOH was 1:2, the mass ratio of 30% H2O2 to MA was 7:10, the epoxidation temperature and time were 65 oC and 0.5 h, and the dosage of the catalyst was 4% of MA. Under the optimal synthetic condition, the yield of ESA can reach 95.68%. The structure of ESA was characterized by Fourier transform infrared spectrometry (FT-IR).
