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

doi:10.7517/j.issn.1674-0475.2003.06.421

Abstract

Abstract: 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.

Key words: phthalocyanine, phthalonitrile, intermediate, biphenyl ether
