Synthesis and kinetic study of a series of chloro- and m-carboxypyridium triazinyl reactive dyes

Five monochloro-s-triazinyl reactive dyes (MCT) and five m-carboxypyridium-s-triazinyl reactive dyes (NTR) were synthesised with the same red chromophore bearing an –NHCN, –OCH3, –CH3NSO2CH3, –N-methyl phenyl or –OH group as ‘second-leg’ substituents. A kinetic study of the hydrolysis of these dyes was conducted, and the rate constant (kobs) and half-life time values were determined. The kobs of the MCT and NTR dyes was found to follow the order –OCH3 > –CH3NSO2CH3 > –N-methyl phenyl > –NHCN > –OH, which was approximately in agreement with the values obtained for the Hammett substituent constants. Overall, the higher the electron-donating property of the substituent on meta-position to the leaving group in the triazine ring, the lower the hydrolysis rate constant.

Synthesis and applications of triazinyl based reactive red dyes

A series of mono and di-chlorotriazinyl based reactive red dyes were synthesized containing the common H-acid nucleus with different reactive coupling groups-sulfanilic acid, metanilic acid, orthanilic acid, anthranilic acid and tobias acid. These syntheses were monitored by thin-layer chromatography (TLC). The solubility of the synthesized dyes was investigated in water at various temperatures. Their Spectrophotometric data indicated significant alteration in their emax values which corresponded to the nature of the substituents (-SO3H, -COOH) of the diazocomponents used. The bi-functional bridged reactive dyes, containing the derivatives of anthranilic acid (KPR-15, KPR-16) showed the highest secondary exhaustion degree from the dyebath while derivatives of tobias acid showed the highest fixation ratio (KPR-19, KPR-20). The improved fastness properties of perspiration, washing and light were investigated. The fabrics with an intense color and good characteristics were obtained, thus presenting a possibility for the extension of usually applied reactive red dyes.
