In this paper, the reaction of eldest amine basic dye with nitrite in hydrochloric acid medium by ultraviolet-visible spectrometry, electrochemistry analysis, Fourier transform infrared spectrometer and nuclear magnetic resonance was studied systematically. The reaction of its structure and effect was preliminarily understood. It is realized that there is diazotization-coupling or diazo-reaction mechanism, generating triazene or diazo-compound. It has magnificent meaning for perfecting, applying this kind of basic dye and instituting a ultraviolet-visible spectrometry or electrochemistry analysis new method of measuring nitrite.
本文采用紫外可见光谱法、电化学分析法、傅里叶变换红外光谱仪和核磁共振仪，系统研究了碱性染料与盐酸介质中亚硝酸盐的反应，初步了解了其结构与效应的反应，认识到存在重氮化偶合或重氮反应机理，生成三氮烯或重氮化合物。这对于完善和应用这类碱性染料以及建立测定亚硝酸盐的紫外可见光谱法或电化学分析新方法具有重要意义。
