摘要
本文采用UV Vis光谱法 ,电化学方法 ,FTIR光谱和NMR波谱法对含伯胺结构的碱性染料与亚硝酸根的反应进行了系统的研究 ,初步摸清了构效关系 ,提出伯胺结构染料与亚硝酸根之间进行的是重氮化偶合或重氮化反应 ,生成三氮烯类或重氮化合物的反应机理 ,对于完善、应用该类碱性染料 ,以及建立测定亚硝酸根的UV Vis光谱、电化学分析新方法有重要意义。
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.
