Title Research on Catalytic Oxidation of ethylbenzene to acetophenone 

Abstract In this text, molybdenum(VI) peroxo complex are synthesized.With tert-Butyl Hydro- peroxide(TBHP) as oxidant and the prepared catalysts,ethybenzene can be efficiently oxidized to acetophenone. The effect of catalyst kind and amount, reactiontemperature, oxidant amount and reaction time were investigated under the following optimal con- ditions: 0.53g of ethylbenzene , 14ml of acetic acid as solvent 0.178g of catalyst and 18g of TBHP ,80 as reaction temperature , time of 36h,the conversion of ethylbenzene and the yield of acetophenone is 98.52%and 90% respectively.The craft route of synthesis of acetophenone by oxidation of ethylbenzene which was studied in this text has many advantages such as environmental friendly,conditions moderately and lowest costing.This experiment will open up a new way that can be followed by green synthesis of other organic compounds and can be viewed as a reference to some extent.
