STUDY OF STABILITY PHYSICAL CHEMICAL OF 3-[2´-THIAZOLYLAZO]-2,6-DIAMINOPYRIDINE AND THE FORMATION OF 3-[N,N-ETHYL-MET-AZO]-2,6-DIAMINOPYRIDINE AS NEW LIGAND CHROMOPHORE

The 3-[2´-thiazolylazo]-2,6-diaminopyridine or 2,6-TADAP have been used as chromophore reagent for the determination of metals of the platinum group. In this work a study of the stability of the 2,6-TADAP is included, a synergetic action of the temperature, the reaction time and the acidity of the m...
