【Abstract】 Synthesis of dimetyl fumarate(DMF) by esterification of fumaric acid with methanol catalyzed by solid superacid /ZrO2-TiO2 was proposed in the paper. Effects of catalyst preparation,raw material ratio,reaction time on the yield of DMF were investigated.Result showed that the catalyst had good catalytic activity.At optimol reaction conditions,the yield of DMF reaches 91.6%.Reusable experiments of the catalyst showed that /ZrO2-TiO2 had good stability.更多还原
