Abstract

KINETIC APPROACH OF OXIDATION OF NICKEL COMPLEX (II) DERIVED FROM 3-[3-HYDROXY -PHENYLIMINO-ETHYL] -6-METHYL-PYRANE-2,4-DION LIGAND IN ACID MEDIUM

Sayyed Hussain*, Takale Surendra, V.G.Mane

ABSTRACT

The kinetic of oxidation of Nickel Complex (II) derived from 3-[3- Hydroxy -Phenylimino-ethyl]-6-methyl-pyrane-2,4-dion ligand by potassium permanganate has been studied in acid medium spectrophotometrically at 520nm. The reaction is first order with respect to KMnO4 as well as Metal Complex concentration. With the increase in concentration of acid the reaction rates increase. The reaction rate has been determined at different temperature and activation parameters have been calculated. Suitable mechanism has been proposed.

Keywords: Kinetics, Mechanism, 3-[3-Hydroxy -Phenyliminoethyl]- 6-methyl-pyrane-2,4-dion ligand, Oxidation, Activation parameters, etc.
