| Abstract: | Dimethyl adipate was synthesized by the reaction of adipic acid and methanol under the catalysis of sodium bisulfate in microwave irradiation fields.The influences of reaction temperature,microwave irradiation time,the dosage of catalyst,and the ratio of reactants on the yield were studied and the main process parameters were optimized as follows: reaction temperature 55℃,reaction time 20min,mole ratio of methanol to adipic acid 6:1,and the dosage of catalyst 4.0g.Under the optimized conditions,the yield of dimethyl adipate can be above 96%. |
