【摘要】 报道不同路易斯酸性催化剂作用下二苯甲酮肟的Beckmann重排反应的结果,即分别以PC l5、H2SO4、HC l-Ac2O、H2SO4-Ac2O、H3PO4-Ac2O、PPA、HC l-Ac2O-AcOH为催化剂进行比较实验.发现H3PO4-Ac2O是二苯甲酮肟进行Beckmann重排反应的理想催化剂之一.更多还原

【Abstract】 The Beckmann rearrangement reactions of diphenyl-methanone oxime in the presence of different Lewis acid catalyst such as PCl₅,H₂SO₄,HCl-Ac₂O,H₂SO₄-Ac₂O,H₃PO₄-Ac₂O,PPA and HCl-Ac₂O-AcOH were studied.The result suggested that H₃PO₄-Ac₂O was an effective and suitable catalyst of the Beckmann rearrangement reaction of diphenyl-methanone oxime.更多还原
