Abstract
Methanol may be in the temperature range 350–500°C catalytically oxidized in one step to acetaldehyde and benzaldehyde over bifunctional catalysts containing the redox active component bi−Mo−O together with the HZSM-5 zeolite. In comparison with HZSM-5 zeolite alone (without the redox active component Bi−Mo−O) a 15 times higher selectivity to C2+ aldehydes was attained. The analysis of the infrared spectra of the surface complexes of methanol formed in its interaction with the proton donor sites of the bifunctional catalyst at 400°C led to the suggestion of the probable mechanism of the oxidative transformation of methanol to higher aldehydes.
