Abstract: The aim of the current study is to identify the dimerization and decomposition kinetics of the F-DM type. The regeneration of F-VS from FiFj-DM or the reversibility of the dimerizations were investigated. The order of real rate constants of the dimerization(Dij) would seem to be similar to that of rate constants of a dimerization(Dij) for VS dyes at a given pH because of the constancy of the equilibrium constants(��aj-value). The reverse reactions of the DM types are appeared to occur in two steps, the deprotonation of �-carbon of the DM types and disproportionation. The ratio of the decomposition of the DM type to F-Hy and F-VS appears to be related with the ratio of ��i/��j. Similarities were also found among various other reactions, including homo- and mixed dimerization. VS dyes undergoing fast hydrolysis have difficulty in forming a dimer. The higher the reactivity with cellulose or hydroxide ion, the smaller the dimerization. The easiness of the dimerization was thus found to be inversely proportional to the rate of hydrolysis. |
