English
Catalytic Oxidation of Diphenylmethane to Benzophenone
Abstract:
Cobalt doped MCM-41 was used to catalyze the oxidation of diphenylmethane to benzophenone.The effect of solvent,amount of acetic acid glacial,reaction time,catalyst concentration,and reaction temperature on the catalyst performance were examined in order to optimize the conversion of diphenylmethane and the selectivity of benzophenone.A 95.8% selectivity to benzophenone was obtained at 21% conversion of diphenylmethane under the optimum reaction conditions:m(diphenylmethane):m(catalyst)=1:10,V(diphenylmethane):V(acetic acid glacial)=1:10,reaction temperature=100℃ and reaction time=10 h.
