Oxidation of para-Methoxy Benzaldehyde and Salicylaldehyde by N-Sodio-N-Chlorotoluene Sulphonamide (Chloramine-T) in Acid Medium: A Kinetic and Mechanistic Study

摘要

The kinetics of oxidation of para-methoxy benzaldehyde and salicylaldehyde by chloramine-T (CAT) have been investigated in hydrochloric acid medium at 303 K. The rate shows frist order dependence on [CAT] and fractional order in [aldehdye]. The rate increases with increase in [HCl] and shows first order dependence on [H~+] and [Cll~-], variation of ionic strength, addition of reaction product (para-toluene sulphonamide) and change in dielectric constant of the medium had no signficant effect on the reaction rate. Thermodynamic parameters are evaluated.
