摘 要: 以2,6-二氯-4-硝基苯胺为原料,与对苯二酚偶联,合成2-(4-硝基-2,6-二氯苯偶氮)对苯二酚。用元素分析,波谱等鉴定其结构,并研究了它与Cu2+、N i2+、Hg2+、Cd2+、Zn2+等金属离子的显色反应。实验结果表明,这些离子的摩尔吸光系数在1.59-6.51×104L.mol-1.cm-1范围。 2 - ( 2,6 - Dichloro -4 - Nitrobenzeneazo) hydroquinone has been synthesized by coupling reaction of 2,6 - dichloro - 4 - nitroaniline with hydroquinone. Its structure was characterized by element alanalysis and spectral data. And its color reaction with Cu^2+ ,Ni^2+ ,Hg^2+ ,Cd^2+ ,Zn^2+ metallic ions was studied, the experiment results showed that its molar absorptivity were in the rang of 1.59 -6.51 × 10^4L. mol^- 1. cm^-1.
