摘要
马来酸酐与甲醇在对甲苯磺酸的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、产品纯度高等优点。
By using p-toluene sulfonic acid as catalyst,esterification reaction takes place be-tween maleic anhydride and methanol.Then the intermediate, dimethyl maleate is isomerized intodimethyl fumarate under light and in the presence of bromine.The method has advantages of sim-ple operation,mild reaction conditions and high purity of the product.
