Synthesis and Absorption Spectra of Monoazo Dyes derived from 2-Methoxy-5-Nitroaniline

J.O. Otutu and E. Osabohien

Abstract:
A series of monoazo disperse dyes have been synthesised from 2-methoxy-5-nitroaniline and their spectral properties were investigated. Six monoazo disperse dyes were synthesised by diazotisation of 2-methoxy-5-nitroaniline using sulphuric acid and sodium nitrite and coupling with 1-hydroxynaphthalene, 2-hydroxynaphthalene, N-phenylnaphthylamine, 1,3-diaminobenzene, 1,3-dihydroxybenzene and 3-aminophenol. The results of the study show that the dyes have the potential to act as disperse dyes for application to polyester and nylon fibres. The dyes were characterized by spectral methods. The solvatochromic behaviour of these monoazo disperse dyes in various solvents was evaluated.
