Abstract: ethyl acetate is an ester of fatty acid is one of the most widely used, can be used as extraction agent and organic synthesis of raw materials, but also can be used as diluent, cleaning agent, flavouring additives etc.. Synthesis methods for inorganic acid catalytic esterification,but inorganic acid as catalyst, there are many side reactions,serious corrosion of equipment, after treatment, environmental pollution and other shortcomings.  In order to overcome this defect, this paper adopts FeCl3 modified cation exchange resin catalyzed synthesis of ethyl acetate,  and systematic study the catalyst loading, catalyst dosage, alkyd material ratio, reaction temperature, reaction time and catalyst on the esterification was investigated. The experimental results show that the catalyst has good catalytic effect, when FeCl3 content is 10%, the dosage of catalyst is 10% of the mass of acetic acid, anhydrous ethanol and glacial acetic acid volume ratio is 1.4:1, temperature is 90 ℃, reaction time was 90min, the yield can reach more than 90% ethyl acetate.
