摘　　要：以SnCl4/C为催化剂,以草酸和正丁醇为原料,微波辐射直接酯化合成草酸二丁酯。通过实验得出最佳反应条件为:醇酸摩尔比为3.5:1,催化剂用量为总投料量的2.5%,微波辐射功率480W,反应30min,收率可达96.8%。Dibutyl oxalate was synthesized by directly esterification using SnCl4/C as catalyst from oxalic acid and butanol. The effects of main factors of reaction on the yield of the product were investigated and The optimal conditions were obtained as follows： molar ratio of alcohol to acid was 3.5：1 ; mass ratio of catalyst was 2.5% ; power of microwave was 480W and the micro- radiation time was 30min. The yield was 96.8%.
