【Abstract】 OBJECTIVE:To improve the synthetic technique.METHODS:The reaction was carried out under the conditions of taking phenylmethyl ether as the synthetic material, acetylchloride as the acetylization agent, aluminium chloride anhydrous as the catalyst, and controlling the reactive temperature. The final products were extracted by ether, dried, then distilled in vacuum, the purified p methoxyacetophenone was obtained.RESULTS:The product rate could be raised from 93.3% to 96.7%.CONCLUSION:This method has high product rate and its reactive conditions are mild and steady.更多还原
