Abstract

The partial oxidation of acetaldehyde and propionaldehyde on a TiO2 supported VO x catalyst in presence of water vapour was investigated in the temperature range from 120 to 280 °C. The selective oxidation to the appropriate carboxylic acids depended on the kind of aldehyde and the reaction temperature. An oxidative cleavage to lower carboxylic acids and CO x was also found. Furthermore, the kinetic model for the process of oxidation of acetaldehyde and propionaldehyde over the V2O5-TiO2 catalyst was developed.
