摘要： 芳基重氮盐在乙醇中的光热分解已有很多研究^[1～7],但分解产物及提出的分解机理不完全统一。

关键词: 二苯胺型重氮盐, 光分解, 热分解

Abstract: The products of the photochemical and thermal decompositions of diphenylamine-4-diazonium salt (DDS), 3-methoxy-diphenylamine-4-diazonium salt (MODDS), N-methyl diphenylamine-4-diazonium salt (NMDDS), and carbazol-3-diazonium salt (CDS) in ethanol were investigated. It was shown that the photochemical decomposition mainly produces ethoxy substituted product of corresponding diazonium salt via the heterolytic cleavage of CN bond. The thermal decomposition, however, produces only the reduced product via the homolytic cleavage of CN bond.

Key words: diphenylamine diazonium salts, photochemical decomposition, thermal decomposition
