Abstract：Zirconium dioxide supported cesium salt of phosphorus tungsten vanadium acid (CsH4 PW10 V2 O40/ZrO2 ) was prepared by impregnation ,and characterized by X‐ray diffraction(XRD) , IR spectra ,the physical adsorption (BET ) and potentiometric titration method .Results indicated that the supported catalyst still maintained a typical Keggin structure ,with strong acidity ,and the specific surface area was also significantly improved .The catalyst exhibited good catalytic performance and sta‐bility in the esterification of acetic acid and ethanol .T hese reaction conditions have obvious influence on the reaction ,w hich including the amount of catalyst ,reaction time and the molar ratio of ethanol to acid .And 93 .9% yield was reached under the optimal condition .After reaction ,the catalyst can be re‐used only through filtration .
