Title: Surface chemistry of benzoyl compounds on oxides, an FT-IR study

Abstract

Adsorption and surface reactions on various oxides have been monitored by IR spectroscopy, with benzaldehyde, benzoic acid, methylphenylketone, and 2-phenyl-2-propanol. The oxides were chosen to represent typical adsorption properties (SiO[sub 2], [gamma]-Al[sub 2]O[sub 3], and [alpha]-Mn[sub 3]O[sub 4]). Surface reactions were observed at various temperatures, starting from room temperature. The results concern three points: (i) identification of adsorbed species, arising on different oxides under increasing temperatures; (ii) the possible sequence of reaction steps in the insertion (oxidation) or removal (reduction) of oxygen, into or from the molecules studied; and (iii) the conclusion that a Cannizzaro reaction is not likely so that the insertion (and removal) is most probably by the Mars and van Krevelen mechanism. 17 refs., 10 figs., 1 tab.
