“…Diketones were reported as products through a rate determining reaction between protonated form of the ketone and oxidants -N-bromo saccharin [35], Nchlorosaccharin [5], Bromamine-T [36] and N-bromosuccinimide [1]. As reported by the earlier authors, the formation of diacetyl as a product of 2-butanone with these N-halogenating agents is unlikely due to the three main reasons viz., (i) In aliphatic series, it has been observed that α-diketone reacts with these halogenating agents much faster than the parent ketone.…”

“…Kinetics of oxidation of ketones by different N-halo oxidants like N-bromo succinimide [1,2], 1,3-dichloro-5,5'-dimethylhydantoin [3], N-chlorosaccharin [4,5], trichloroisocyanuric acid [6,7], N-bromosaccharin [8] have received considerable attention. A thorough literature survey showed that till the date, reactions between dichloroisocyanuric acid (DCICA) and ketones were not studied.…”

ABSTRACT. Kinetics of reactions of enolisable ketones (S = acetone/2-butanone) with dichloroisocyanuric acid (DCICA) were studied in aqueous acetic acid and perchloric acid media in absence and presence of added chloride ions. The reactions were found to be pseudo zero order and pseudo first order on [DCICA] in absence and presence of chloride ions respectively. Both in presence and absence of chloride ions, first order and fractional order in substrate and perchloric acid were observed respectively. An increase in the rate of reaction was observed with an increase in chloride ion concentration as well as acetic acid composition. The results were interpreted in terms of probable mechanisms involving (i) rate-determining enol formation from the conjugate acid of the ketone (SH + ) in the absence of added chloride ions and (ii) rate-determining interaction of SH + with the most effective molecular chlorine species produced by the hydrolysis of DCICA (rather than a rate-determining interaction of enol with chlorine) in the presence of added chloride ions, prior to the rapid steps of product formation.

Kinetics of palladium (II) catalyzed oxidation of D-(+) galactose by cerium (IV) have been studied titrimetrically in aqueous acidic medium in the temperature range 308-333 K. The reaction has been found to be first order with respect to D-(+) galactose in catalyzed reactions. The rate of reaction decreases with increasing sulphuric acid. The reaction proceeded through formation of an intermediate complex, which was proved by kinetic method. The observed stoichiometric ratio was 1:2 in the oxidation of D-(+) galactose. From the effect of temperature on the rate of reaction, the Arrhenius equation and various activation parameters have been computed. Arabinose and formic acid have been identified as main oxidation products of the reaction. A plausible mechanism from the results of kinetic studies, reaction stoichiometry and product analysis has been proposed.
