Abstract
The kinetics of oxidation of neopentyl glycol by diperiodatocuprate(III) in alkaline medium had been studied spectrophtometrically in the different of temperatures range of 25-45 °C. The reaction of neopentyl glycol is the first order in each [diperiodatocuprate(III)] by experiment determination. The rate constant kobs increased with increase in [OH-] and [neopentyl glycol]. However, with the increase of the temperature, the kobs decreased with increase in [IO4-]. The reaction constants which involved in the different steps of the mechanisms are calculated. Activation parameters which controlled by slow step of the mechanism are discussed and thermodynamic quantities are determined. Therefore, the activation parameters at 298.2 K were calculated.
