Abstract

Kinetics and thermodynamics of dyes derived from p-amino toluene sulphone-N-ethylanilide as diazocomponent on wool and nylon 66 substrates are hereby reported. The activation energy of diffusion decreased as the number of suphonic acid groups increased. It was also observed that dyes that exhibited azo-hydrazone tautomerism gave lower activation energies than identical dyes that did not show the same effect. Monosulphonated dyes recorded higher values of heat and entropy of dyeing than the disulphonated ones.
