KINETICS OF OS (VIII) CATALYZED OXIDATION OF ALANINE BY FERRATE (VI) IN ALKALINE MEDIUM
Sheila Srivastava* and Dharmraj Prajapati
ABSTRACT
Spectroscopic investigations on Os(VIII) catalysed oxidation of alanine by in basic medium have been carried out at room temperature (30oC).The rate of oxidation shows a first-order dependence on oxidant,catalyst, Os(VIII). Small increase in rate of reaction is observed with the increase in concentration of OH- & [S] i.e., positive effect of increase of [KOH] & [S] is observed. Negligible effect of addition of [KCl] and [KNO3] on rate is observed. [OsO4(H2O)2] and are proposed to be the reactive species of Os (VIII) and Fe (VI) respectively in the present investigation. Acetaldehyde is found to be main product of the reaction Keywords: Alanine, Os (VIII) catalysis, Oxidant Ferrate (VI) and Kinetics. [Download Article] [Download Certifiate] |
