Oxidation of propylene, acetone, and acetaldehyde adsorbed on Sn-Mo oxides
An IR spectroscopic study revealed that propylene, ethylene, and acetone adsorbed associatively on aerosil-supported 9:1 tin-molybdenum binary oxides. On heating the adsorbed propylene to 200/sup 0/C, dehydrogenation of the adsorbed species by lattice oxygen and formation of surface hydroxyls occurred. In the presence or absence of oxygen at 0/sup 0/-150/sup 0/C, no formation of carboxylate ions was observed. Acetone adsorbed as a coordinately adsorbed and a dissociatively adsorbed species; increasing the temperature in the presence of oxygen again produced only surface hydroxyls by dehydrogenation, but no carboxyl ions. Acetaldehyde apparently adsorbed by coordination and was oxidized to acetate by lattice oxygen when the temperature was raised. Table, spectra, and 17 references.
