Abstract

The selective oxidation of 1-butene and 1,3-butadiene was studied by transmission infrared spectroscopy. Vanadium-phosphorus-oxygen catalysts prepared by the reaction of V2O5 with H3PO4 in alcohol solution were used. Infrared spectra were collected in situ during the flow of 75 cm3 of 1.5% hydrocarbon-in-air mixtures over catalysts having P-to-V ratios of 0.9, 1.0, and 1.1. Reaction temperatures from 300 to 400°C were investigated with 1-butene feeds, whereas the highly reactive 1,3-butadiene was studied only at 300°C. An adsorbed butadiene species, maleic acid, and maleic anhydride were observed during both olefin partial oxidation studies. Evidence was obtained for a second olefin species which had been previously observed for in situ n-butane selective oxidation studies. Concentrations of adsorbed species were found to vary with catalyst phosphorus loading, reaction temperature, and time of exposure to reaction conditions.
