| Abstract: | The catalytic characteristics of PW_(12) heteropolyacid supported on several domestic activated carbons were investigated for the esterification of acetic acid with terpineol in the liquid-solid system.XRD and NH_3-TPD of catalyst were studied in detail.Different activated carbons had remarkably different adsorption strength for PW_(12).The effects of reaction conditions were studied.The most suitable conditions for the reaction were obtained.The results showed that this catalyst had a higher catalytic activity,which made the produce process of the esterification of acetic acid easy,also it could easily be recovered and could be used repeatedly many times. |
