偶氮连苯三酚试剂的合成及其光谱特性

Synthesis and Spectral Properties of Azo-Pyrogallol Reagents

合成了 2 -羧基苯胺重氮盐和 2 -羟基苯胺重氮盐 ,它们与连苯三酚偶联 ,得到新的偶氮试剂 4 - (2 -羧基苯偶氮 ) -连苯三酚和 4 - (2 -羟基苯偶氮 ) -连苯三酚。研究了偶氮试剂的红外光谱、紫外光谱和荧光光谱特性。

2-Carboxyanilineazo salt and 2 hydroxyanilineazo salt were synthesized,and new azo reagent 4 (2 carboxyanilineazo) pyrogallol and 4 (2 hydroxyanilineazo) pyrogallol were synthesized through coupled reaction of 2 carboxyanilineazo salt and 2 hydroxyanilineazo salt with pyrogallol.IR,UV and fluorescence spectrum of the two azo pyrogallol reagents were studied.
