Diethyl 2,6-pyridinedicarboxylate was synthesized under microwave irradiation by using 2,6-pyridinedicarboxylic acid as raw material,concentrated sulfuric acid as catalyst.The effects of the dosage of catalyst,microwave radiated time,the molar ratio for raw materials and microwave radiated power on the yield were investigated.The results showed that The optimum reaction conditions were as follows: the concentrated sulfuric acid was 2ml(0.037mol),microwave radiated time was 30 min,the molar ratio of alcohol to acid was 24:1 and the microwave radiated power was 200W.The yield of product was 79.3% in the optimum reaction conditions.
