邻氨基酚合成中氧化副产物2-氨基吩嗪-3-酮的研究

Study of 2-Aminophenoxazine-3-one—the By-product in the Synthesis of o-Aminophnol

２－氨基吩嗪－３－酮作为邻氨基苯酚合成中的副产物被成功地分离出来，并与合成样进行了对比，作了光波谱鉴定。

Abstract 2-Aminophenoxazine-3-one was separated during the synthesis of o-aminophenol(OAP).It was identified by IR,1HMP and contrasted by TLC with the standard sample,the changing of colour in different pH value was observed.
