摘　　要：以顺丁稀二酸酐与仲辛醇为原料 ,以硅钨杂多酸为催化剂催化合成马来酸酯。研究了催化剂的用量 ,酯化、磺化反应时间 ,酸醇物质的量比对反应的影响。催化剂可多次使用催化效果较好。Maleic acid ester is synthesized with the fourth sparse diacid anhydride and sec octyl alcohol as raw materials and silecon tungsten heteropoly acid as the catalyzer. The amount of the catalyzer used and the reaction time of esterification and sulfonate and the effect of the mole ratio of the acid and alcoho are researched. The catalyzer can be reused and the effect is satisfactory.
