【摘要】 马来酸酐与甲醇在强酸性阳离子交换树脂催化作用下发生酯化反应，所得产物马来酸二甲酯再在溴存在下经光照即可异构化成富马酸二甲酯．该法具有操作简便、反应条件温和、产物纯度高等优点．更多还原

【Abstract】 By strongly acidic cationic exchange resin as catalyst, esterification reaction take place between maleic anhydride and methanol.Then the intermediate,dimethyl maleate is isomerized into dimethyl fumarate under light and in the presence of bromine. The method has advantage of simple operation, mild reaction conditions and high purity of the product.更多还原
