Abstract

The hydrolyses of ten VS dyes were examined at 40$^{\circ}C$, 50$^{\circ}C$, and 60$^{\circ}C$ and the kinetic parameters were estimated. The values of free energy, enthalpy and entropy of hydrolysis and reaction with cellulose for VS dyes were calculated. The linear relationship exist between the enthalpy and entropy. The structure and entropy of VS dyes gave a effect on the dimerization for VS reactive dyes. The VS dyes have small value of entropy were formed dimer. It was confirmed that no dimer form for m-substituted VS dyes. There were similarities among various reactions including homo- and mixed dimerization.
