Abstract
Oxidation of acetylacetone (AA) by chloramine-T (CAT) and bromamine-T (BAT) in the presence of HCl (0.1-0.6 mol dm-3) at constant ionic strength (1.0 mol dm-3) over the temperature range (303-318 K) obeys the rate law, rate = kOx]AA]xHCl]y where x and y are less than unity. Addition of the reaction product, p-toluenesulphonamide and variation of ionic strength of the medium have no effect on rate. The rate increases in D2O medium. Activation parameters for the overall reactions have been computed. Michaelis-Menten type of kinetics has been proposed and activation parameters for the rate limiting step have been computed. The mechanism involves simultaneous catalysis by H+ and Cl- ions and the, interaction of haloamine species with the enol form of the diketone.
