Titanium (III) reduction of dimethylglyoxime: Electrochemical and kinetic studies

Abstract

176-179Titanium (III) mediated electroreduction of dimethyl glyoxime has been carried out in aqueous sulphuric acid medium and the reduction product has been isolated and characterised. The kinetic investigations have been carried out under stoichiometric and non-stoichiometric conditions at 306K. It has been found that the reaction follows overall second order kinetics, first order each in [Ti(III)] and [DMG] and fractional order in sulphuric acid. The effect of varying concentrations of Ti(III), DMG, H2SO4, ionic strength, and solvent composition has been studied. Effect of temperature has also been studied and activation parameters have been computed from Arrhenius and Eyring plots
