摘　　要：本文探讨了标题合成方法中合成反应条件对酯收率的影响。其最佳反应条件为:n(醇)∶n(酸)=2.5∶1.0,固体超强酸用量为反应物总质量的2.0%,微波辐射功率528W,辐射时间20min,酯收率达89.5%。用IR等手段对产品进行了确证。We considered the effect of reaction condition to the yied. The best condition is that the ratio of alcohol to acid is 2.5∶1.0, and the amount of solid super acid is 2.0% of total mass of reactants, the power of microwave is 528 W, radiation time is 20 min, the yield may up to 89.5%. Structure of the product was identified by methods of IR.
