Abstract
The selective oxidation of propane to oxygenated products (isopropanol, n-propanol, propionic aldehyde and acetone) mediated by the Fe(II)/H 2O 2 Fenton system at 80 °C in the presence of solid acid and superacid promoters containing S and F moieties has been studied. The occurrence of a radical reaction pathway accounting for the activation of the C H bonds of the propane molecule by OH radicals has been proved by assessing the inhibiting effect of both Cl − and NO 3 − radical scavengers and organic (CH 3COOH, CH 3CN, DMSO) reaction media on the reaction pattern. S and F functionalities of several solid agents promote the electron transfer processes controlling the H 2O 2 activation. Any effect of the Brönsted acid features of the solid promoters on the reaction kinetics and pathway has been disregarded.
