Abstract

Acylation of anisole in vapor phase with acetic anhydride in a fixed bed reactor was carried out over different ferrites. The conversion of anisole was 98.50% and selectivity of 4-methoxy acetophenone (4-MAP) found to be 99.24%. The maximum yield was observed by variation of the molar ratio, weight hour space velocity (WHSV), catalysts and temperature. The activity of the catalyst different with the acidity due to ionic distribution in the spinel lattice of the ferrite system. The catalytic activity plays an important role in conversion of reactant.
