四(α-高歧化度烷氧基)酞菁合成关键步骤的研究

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.

THE KEY STEP FOR THE SYNTHESIS OF HIGH-BRANCHED ALKOXY PHTHALOCYANINE

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.
