【Abstract】 Objective To investigate the isomerization of monomethyl maleate catalyzed by the combination of H 2NCSNH 2,HCl and NaHSO 3.Methods Orthogonal experiment and analysis of variance were used.Results The use level of HCl and the reaction time had statistical difference respectively,but the use level of H 2NCSNH 2 and NaHSO 3 hadn’t.Conclusion For the isomerization of monomethyl maleate,the use level of HCl and the reaction time has high significance influence respectively,but the use level of H 2NCSNH 2 and NaHSO 3 hasn’t.更多还原
