Title: Study on synthesis of methyl gallate catalyzed by heteropolyacid-loaded activated carbon.
Abstract: Methyl gallate was synthesized using the catalyst of H7PW12O42·4H2O(PW12) heteropolyacid supported by activated carbon(AC).The characteristics of the catalyst was investigated in detail including XRD analysis,N2 adsorption and NH3-TPD.The effects of catalyst on reaction conditions were studied.The results showed that under following conditions: gallic acid 0.52mol,methanol 0.4mol,loading amount of PW12 on AC 30%,reaction time 4h and catalyst dosage 5%,the yield of MG could reach 90.1%.The catalyst had a high catalytic activity,could be recovered easily and used repeatedly.
