✦ Synopsis

Abstract

The oxidation of butane 2,3‐, propane 1,2‐, ethane diol and 2‐methoxy ethanol in aqueous alkaline medium by Os(VIII) has been studied. The reaction is base catalyzed and shows first‐order kinetics in Os(VIII), whereas the order is less than 1 in butane 2,3‐diol [BD]. The rate of oxidation is BD > propane 1,2 > ethane diol ≈ 2‐methoxy ethanol. The change in ionic strength has no effect on the rate of reaction. Activation parameters Δ__E__, PZ, and Δ__S__* have been evaluated.
