以马来酸酐、环己醇为原料,固体超强酸SO42-/SnO2-CeO2为催化剂,一步完成酯化异构化合成富马酸单环己酯。采用FTIR和GC-MS对产品进行了表征分析。通过正交实验设计得出反应的适宜工艺条件:反应温度100℃,反应时间5 h,催化剂用量2.5 g(以0.1 mol马来酸酐为基数),醇酸摩尔比为1.5∶1,在此条件下富马酸单环己酯产率为57.65%。

Using maleic anhydride and cyclohexanol as raw material and solid super acid SO2-4/SnO2-CeO2 as esterification and isomerization catalyst,mono-cyclohexyl fumarate was synthesized by one step process.The products were confirmed by GC-MS and FTIR spectrum.The optimum conditions obtained by orthogonal experiments are as follows: reaction temperature 100 ℃,reaction time 5 h,catalysts dosage 2.5 g,n(cyclohexanol)∶ m(maleic anhydride)=1.5∶ 1,the yield of mono-cyclohexyl fumarate was 57.65%.
