Synthesis and Characterization of Some Mono Chloro-S- Triazine Vinyl Sulphone Reactive Dyes

Abstract

A series of ten bifunctional mono-chloro-s-triazine vinyl sulphone reactive dyes were synthesized based on Hacid with varied substituents coded as (BRD). These dyes were characterized by IR spectroscopy. The results revealed an incorporation of various substituents. The visible absorption spectra of these dyes were examined in various solvents and results shows positive and negative salvatochromism as the solvent polarity; changes, melting point, percentage yield and molar extinction co-efficient of these dyes were also evaluated and the results obtained are within a reasonable range acceptable for commercial dyeing.
