Micelle catalyzed oxidation of propan-2-ol to acetone by penta-valent vanadium in aqueous acid media

Abstract

Vanadium (V) oxidation of propan-2-ol shows a first-order dependency on the concentrations of propan-2-ol, vanadium (V), H+ and . These observations remain unaltered in the presence of externally added surfactant. The effects of the cationic surfactant (i.e. CPC), anionic surfactant (i.e. SDS) and neutral surfactant (i.e. TX-100) have been studied. CPC inhibits the reactions whereas SDS and TX-100 accelerate the reaction to different extents. Observed effects have been explained by considering the hydrophobic and electrostatic interactions between the surfactants and reactants. SDS and TX-100 can be used as catalysts in the production of acetone from propan-2-ol.
