Synthesis and Characterization of Diazo Dyes Derived from Analine Derivatives and Salicyclic Acid

The heterogeneity of diazo dyes obtained from analine derivatives were artificially manufactured by diazotizing agents such as bromo analine and nitroanaline with coupled naphthol and salicylic acid. The dyes that contained impurities were recrystalized using ethanol as a solvent. Satisfactorily. The entire manufactured dyes showed good quality and reliability properties of diazo dyes. The diazo dyes were subjected to UV-VIS and IR which indicated the wavelength and functional group of the dyes respectively. The UV spectral of the dyes reveals spectral band position to a longer wavelength in the solvent of different polarities. When dyeing was performed on different materials, polyester material preeminent impact properties. Dyeing was carried out on nylon, cotton and polyester fabrics. Remarkably, nylon gave the earnest dye depth, while polyester has the preeminent fastness properties.
