The triesters of C_ ( 22)-tricarboxylic acid could be prepared by the Diels-Alder adduct using methyl ester of cottonseed oil as raw material, change non-conjugated methyl linoleate into conjugated methyl in the presence of catalyst, then react with diesters of fumarate.
C22-三元酸三酯的合成以棉籽油甲酯为原料，将非共轭的亚油酸甲酯在催化剂作用下转化成共轭亚油酸甲酯，同时与富马酸二酯发生Diels-Alder反应，生成C22-三元酸三酯。
By esterification reaction of fumaric acid with methanol, Synthesis of dimethyl fumarate catalyzed by heterogeneous supported heteropoly acid PW 12/ C was studied in this paper.
以富马酸与甲醇为原料，固载杂多酸PW12/C为催化剂合成了富马酸二甲酯。
Furfural was used as the raw material with potassium chlorate as the oxidant to prepare fumaric acid, which was then esterified with methyl alcohol using phosphotungstic acid as the catalyst to produce dimethyl fumarate. The overall yield was up to 73%.
以糠醛为原料，先用氯酸钾作氧化剂氧化制得富马酸，再用磷钨酸作催化剂与甲醇进行酯化制得富马酸二甲酯，总产率可达73%。
