Abstract

Kinetics and mechanism of oxidation of D-mannitol by potassium bromate in aqueous acidic medium

Kinetic investigation in Rh(III) catalyzed oxidation of D-Mannitol in an acidified solution of potassium bromate in the presence of Hg(OAc)2 as a scavenger, have been studied in the temperature range of 300 - 450 C. Increase in concentration of oxidant and H+ ion showed fractional positive order and fractional inverse order respectively. The influence of Hg(OAc)2, ionic strength and Cl- ion on the rate was found to be insignificant. First order kinetics was observed in case of catalyst Rh(III) , Rh+3 being its reactive species. The order of reaction w.r.t. substrate is zero. The various thermodynamic parameters were calculated from rate measurements at 30, 35, 40 and 45 0C respectively. A suitable mechanism in conformity with the kinetic observations has been proposed and the rate law is derived on the basis of obtained data
