| Abstract: | Taking succinic acid, alcohol as material, cation exchange resin as catalyst the diethyl succinate is synthesized. The condition of the kind and quantity of catalyst, the material mix ratio, the reaction time and the using times of catalyst are discussed. The experiment confirmed the kind of catalyst and the best technical condition. The result shows, HD - 8 strong acidity ion exchange resin is the best catalyze and high selection, it can be used serval times, ester rate in 76.4% . The quality of production accords with country standard with satisfactory results. The operation of technology is simple, the control of condition is easy, it has not pollution. |
