Abstract :

Oxidation of alcohols by organic oxidants has been widely reported in literature but very few reports are available on the use of inorganic oxidants to oxidize alcohols to the corresponding carbonyl compounds. This paper deals with the first order kinetics of the controlled oxidation of the industrially important cyclic alcohols, Cyclopentanol,Cyclohexanol and Cylcooctanol by KIO₄ in acidic medium. Cyclopentanol is used in the preparation of dyes and pharmaceuticals and Cyclohexanol is used as a feedstock in the polymer industry as a precursor to nylon and plasticizers.

The oxidation rate was monitored by titrimetric analysis of the unreacted inorganic oxidant at regular time intervals. The oxidation rates of the cyclic alcohols increased with alcohol concentration but decreased with oxidant concentration. The thermodynamic activation parameters were determined from the variation of oxidation rate with temperature. A suitable reaction mechanism has been suggested for the oxidation of the cyclic alcohols under study. The oxidation rates of alcohols follow the sequence: Cyclopentanol > Cyclohexanol > Cyclooctanol which has been explained on the basis of their ring size and stability.
