摘 要: 以2-氨基-5-溴嘧啶为原料,经重氮化后与对苯二酚偶联,合成2-(5-溴嘧啶偶氮)对苯二酚.用元素分析、波谱等鉴定其结构,并研究了它与Cu^2+,Ni^2+,Co^2+,Cd^2+,Ag^+等金属离子的显色反应.结果表明,这些离子的摩尔吸光系数8达到2.56~8.23×10^4L·mol^-1·cm^-1. 2 - ( 5-bromopyrimidineazo ) h bromopyrimidine with hydroquinone. Its ydroquinone has been synthesized by coupling reaction of 2-amino-5- structure was characterized by element analysis and spectral data. And its color reaction with Cu^2+, Ni^2, Co^2+, Cd^2+ and Ag^+ metallic ions was studied. The experiment results showed that its molar absorptivity were in the range of 2.56~8.23×10^4L·mol^-1·cm^-1.
