Solvent influence on absorption spectra of food azo dyes

open access: yesZaštita Materijala, 2019
The solvent influence on absorption spectra of food azo dyes was examined by the method of Linear Solvation Energy Relationships (LSER). For this purpose, six azo dyes were used: tartrazine (E 102), ponceau 4R (E 124), azorubin (E 122), brilliant black ...

Synthesis and solvatochromism of some hydroxy substituted phenyl azo pyridone dyes

open access: yesZaštita Materijala, 2023
Aryl azo dyes are widely used due to their excellent physicochemical properties (primarily high value of the molar extinction coefficient and great resistance to light and wet processing) and the fact that can be obtained in a simple method of ...
