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.
