Kinetics and mechanism for alkaline hydrolysis of C. I. Disperse Green 9(G-9) of dinitrothiophene
disperse dye were investigated. As soon as G-9 contacted with alkali, instant and continuous decreases of color
strength of G-9 followed with increasing time. The hydrolysis rate of G-9 increased with increasing alkali, and it
was found that alkali appeared first order dependence. The observed rate constants obtained from hydrolysis of
various amount of dye were similar values, and calculation of initial rates showed that G-9 hydrolyzed by first
order reaction for dye. Therefore it was confirmed that the overall reaction was second order, SN2 of nucleophilic
substitution reaction. Increasing temperature enhanced the hydrolysis of G-9. From the results of hydrolysis
performed at various temperatures, it was obtained that activation energy(Ea) was 12.6 kcal/mole, enthalpy of
reaction(ΔH) was 12.0 kcal/mole, and entropy of reaction(ΔS) was 29.8 J/mol․K. |
