Keywords: 3-chloro-4-fluoroaniline, disperse dyes, diazotisation, solvent effects, Absorption spectra.
A series of new monoazo disperse dyes derived from 3-chloro-4-fluoroaniline have been
synthesized The six novel monoazo disperse dyes were synthesized by diazotisation of 3-
chloro-4-fluoroaniline and coupling with 1 -naphthylamine, 6-methoxy-2-naphthol, Nphenylnaphthylamine,
3-aminophenol, 1,3-dihydroxybenzene and 2-naphthol. The dye
structures were eluciated by chemical analyses and spectral methods. The solvatochromic
behaviour of these monoazo dyes in various solvents was evaluated.
