偶氮染料的偶氮-醌腙互变异构的研究(Ⅱ)──2-苯基偶氮-1-萘酚的偶氮-醌腙异构

AZO-HYDRAZONE TAUTOMERISM OF 2-PHENYLAZO-1-NAPHTHOL DERIVATIVES

合成并测定１１个２－苯基偶氮－１－萘酚料的Ｈ、＾１３ＣＮＭＲ谱，对氢谱进行了归属，讨论了苯环取代基的电子效应、溶剂的ＰＨ值对偶氮－醌腙互变异构以及结构对颜色的影响。

Eleven 2-phenylazo-1-naphthol dyes have been synthesized,and the H,C NMR spectra are recorded.The electron effect of substituents on the benzene ring,and solvent pH effect on azo-hydrazone tautomerism,as well as the relationship between the molecular structure and the colour are discussed.
