Abstract	The kinetics of Oxidation of borneol (C10H18O) [endo-1, 7, 7-Trimethyl bicyclo (2, 2, 1) heptan-2-ol] by aqueous perchloric system, yields of ketone in the presence of Trichloroisocyanuric acid at 300C. The stoichiometry is (1:1) and the main oxidation product is Camphor which is studied by TLC using benzene as a solvent and by spraying with 2, 4-dinitrophenyl hydrazine reagent. The observed rate of oxidation shows a first order dependence on both borneol and TCICA (Oxidant). Jr. of Industrial Pollution Control 25 (1) (2009) pp 1-8 © Enviromedia Printed in India.

The Oxidation of Borneol has been studied by chlorine15 and copper (II)-ß-cyclodextrin in pyridine acetic acid-hydrogen peroxide system16, but there is no references in the literature on the oxidation of borneol by TCICA. Hence we have undertaken the study of the kinetics of the oxidation Borneol [substrate] with TCICA [oxidant]. Authors studied the kinetics of oxidation of ketones by TCICA in aqueous acetic acid medium in presence of HClO4. The reaction was acid-catalyzed exhibiting first order dependence each in (acid) and (substrate) and zero order dependence in (oxidant). Assuming an acid catalyzed enolisation of ketones in the rate determining step followed by oxidation of enol in a fast step and the
