The mechanism of alcohol oxidation over MoO/sub 3/ has been examined by using temperature-programmed desorption spectroscopy (TPD) with simultaneous microbalance and mass spectral detection. Two types of experiments are reported. The alcohol structure has been varied over the sequence methyl, ethyl, 2-propyl, tert-butyl, and systematic changes in the amount of chemisorption, the peak desorption temperature, and the nature of the products have been observed. The amount of water produced during chemisorption of ethyl alcohol on MoO/sub 3/ at room temperature has been measured. This determination makes it possible to estimate the coverage of alkoxy groups after the chemisorption stage. The fate of these ethoxy groups during subsequent TPD can be followed. A stoichiometric accounting of both acetaldehyde production and catalyst reduction can be made.
