AbstractThe kinetics of formation of azo dyes formed by reactions of donors 2,4-dihydroxy benzaldehyde or its, oximes (Syn and Anti), with accepter diazotized sulphanilic acid sodium salt reagent at pH7. The ratios of concentrations of dyes, reactants had values of (1:10:2.5) for (Aldehyde or its, oximes: reagent: base) respectively. Experimentally, it was proved that dyes formation followed a pseudo first order kinetic with respect to the aldehyde and its, two oximes (Syn and Anti).The kinetics of dyes formation were studied at optimal conditions for the dyes and at a range of temperature (10-50 ○C). Rate constants (k), half lives (t1/2) and activation parameters, namely, (Ea, ∆H*, ∆S* and ∆G*) were determined. All these parameters were discussed and interpreted.
