✦ Synopsis

Abstract

The kinetics of decomposition of [PVA. Mn^VI^O‐] intermediate complex have been studied spectrophotometrically. A first‐order dependence on the intermediate concentration was observed. The decomposition rate was found to be base‐catalysed. The kinetic parameters have been evaluated and a mechanism consistent with the results obtained is discussed.

## Abstract The kinetics of formation of the [PVA. Mn^VI^O] intermediate complex have been measured by the conventional spectrophotometric technique. The rate of formation of the complex was found to be given by the expression d[Complex]/d__t__ = __k__~1~[MnO‐~4~][PVA^−^]. The results showed that t

The kinetics of oxidation of tetrahydrofurfuryl alcohol by dihydroxydiperiodatonickelate (IV) complex in the temperature range of 20-35°C has been studied by spectrophotometry in aqueous alkaline medium. The reaction order in [Ni(IV)] was found to be unity and that in [alcohol] to be 1.64-1.69. The
