Dehydration and Dehydrogenation of 2-Propanol over Graphite Oxide

Abstract

The dehydration and the dehydrogenation of 2-propanol took place over a graphite oxide catalyst to form propylene and acetone, respectively. The reactions proceeded by zeroth order kinetics. The formation of ether was not observed. Since the dehydration takes place over the acid sites and the dehydrogenation over the base sites, the presence of both acid. and base sites is suggested on the graphite oxide surface. The rate constants and the activation energies of dehydration and the dehydrogenation are: 3.61×10^-3 mol/⋅gmin and 100nwl for propylene and 2.07×10^-3mol/g⋅min and 104 k J/I-nol for acetone, respectively.
