Abstract:Diethyl adipate is synthesized by solvent - free catalysis with iodine as catalyst. The effects of reaction time, raw material ratio, catalyst amount and reaction temperature on the yield of diethyl adipate are discussed. The result shows, the optimum reaction conditions is: adipie acid amount 0. 020 tool, the molar ratio of ethyl alcohol and adipic acid 6 : 1, catalyst amount 0. 060 g, reaction time 4.0 h, temperature 84 -85 ℃ ,the yield is up to 94.68 %.
Keywords:diethyl adipate  iodine  synthesis  catalysis
