Synthesis of Ethyl Acetate Using Cation Exchange Resin as Catalyst

The esterification reaction of acetic acid and ethanol using cation exchange resin DOWEX MARATHON C as catalyst was investigated.The catalyst activity and the converting rate of process were discussed under experimental conditions of the reaction temperature,catalyst amount,initial reactants molar ratio and reaction time.The optimal conditions obtained by the orthogonal design experiment for the esterification reaction with the yield up to 62% is that reaction time 55 min,reaction temperature 70℃,catalyst amount 110 g/L and reactants molar ratio of ethanol to acetic acid 1.5∶1.
