摘　　要：烷氧基邻苯二腈是酞菁合成的重要中间体,但高歧化度烷氧基邻苯二腈的合成由于副产物多,产率低下而成为此类酞菁应用的"瓶颈".文中对反应副产物进行了分离纯化,并利用红外、气质联用、1HMR和元素分析等测试手段对其进行了表征.且根据测试数据推导出了副产物结构式为1,2,1'2' 四腈基 3,3' 二苯基醚.这一副反应机制的阐明,对于寻求对主反应有利的条件,具有重要的意义.Alkoxy phthalonitrile is an important intermediate for the synthesis of highbranched alkoxy phthalocyanine potentially used in practice.However,the synthesis of the highbranched alkoxy phthalonitrile is confirmed experimentally to be the key step,whose byreaction and lower yield are considered to be the bottleneck of synthesis of whole alkoxy substituted phthalocyanines.In order to clarify the byreaction's mechanism and inject new insight to improve this key step,the byproduct was separated,purified and characterized by IR,MS,1HNMR and elemental analysis.Based on these data,the main byproduct's molecule structure was deduced and discussed.
