Abstract
Reactivity and stability of a bis(monochloro-s-triazine) reactive dye (C.I. Reactive Red 120) between 90 and 130 °C at various pH values were studied using HPLC. The obtained rate constants for the hydrolysis of the dye show that the reactivity in the range of 100 °C to 130 °C and at pH values lower than 10.0 is close to the reactivity at 90 °C and pH 11.0, indicating that severe hydrolysis of the active groups of the dye could be avoided at high temperatures by lowering the pH. Meanwhile, the concentrations of the degradation products of the dye at high temperatures, as determined from its chromatographic analysis, were found to be far higher than that at low temperatures, while those of the hydrolysis products did not significantly vary with temperature. These results show that most of the losses of the dye at high temperatures and low pH are caused by the degradation, rather than hydrolysis, of the dye.
