Abstract: The modification solid catalyst HMS by phosphotungstic acid was prepared by insitu synthesis from DDA, TEOS, and phosphotungstic acid, and applied in pMethoxy acetophenone production with the FriedelCrafts acylation reaction of phenyl methyl ether and Acetic anhydride.The factors including reaction temperature, reaction time, catalyst amount, reactants molar ratio phenyl methyl ether to Acetic anhydride on the FriedelCrafts acylation reaction were investigated. The experimental effects show that solid acid catalyst HMS has high catalytic activity.The acylation reaction conversion can reach 83.1% and the selectivity of pMethoxy acetophenone production is 97.3% under the following optimal conditions: reaction temperature of 100 ℃, reaction time of 4 h, amount catalyst of 0.15 g, molar ratio of n( anisole)∶n(acetic anhydride) =1∶1.5.
