顺丁烯二酸-2-乙基已酯合成方法的研究

Synthesis of Diisooctyl Maleate

辛醇和顺丁烯二酸酐在酸根的作用下可以生成顺丁烯二酸-2-乙基已酯。采用阳离子交换树脂作催化剂，醇过量的方法制取顺丁烯二酸-2-乙基已酯。考查了反应温度，催化剂用量，酸醇比，反应时间等条件对反应转化率及收率的影响，确定了最佳反应条件，并指出合理的转化率应该在98．2％-98．5％。

Synthesis Diisooctyl Maleate by using maleic anhydride and iso -octanol as materials, ecess mole ratio alcohol to anhydride is used, studied the effect of catalyst, temperature, mole ratio and reaction time on the yield. , got the optimal reaction condition and point out that the reasonable yield should be 98.2% - 98.5%.
