Department of Chemistry, Shivaji University, Kolhapur-416 004 Manuscript received 23 October 1987, revised 18 .April 1988, accepted 3 June 1988 Kinetic investigations of oxidation of salicylic acid hydrazide and o-chlorobenzoic acid hydrazide in presence of alkaline methanol by chloramine-T (CAT) have been carried out at \(30^o\). The end-products of the oxidation are bishydrazides, p-toluenesulphonamide and nitrogen. The rates were determined at different temperatures and activation parameters

... were evaluated. Zero effect of added salt, p-toluenesulpho- namide and pH of medium was observed. The mechanism in which chloramine-T reacts with hydrazide giving acyldi-imide as an intermediate in the slow and rate determining step has been proposed.
