  1. 1.

    An investigation was made of the activity of vanadium oxides in the dehydrogenation of cyclohexane, and the dehydrogenation and dehydration of ethyl and isopropyl alcohols. It was found that the relative dehydrogenating and hydrogenating capacity of vanadium oxides increases in the case of both alcohols and hydrocarbons as they are reduced to V2O2, and is maximal for V2O3. Corresponding samples were investigated by x-ray diffraction methods.

  2. 2.

    Over the temperature range 450–500°, vanadium trioxide produces dehydrogenation of cyclohexane with up to 10% conversion and, in contrast to vanadium pentoxide, it produces hardly any side processes (the gas consists of 97–99% H2). The activation energy of this reaction was determined.

  3. 3.

    Vanadium trioxide has a dehydrogenating and a dehydrating action on alcohols and there is a secondary reaction with the hydrogen formed. The activation energies for the dehydrogenation and dehydration of ethyl and isopropyl alcohols were calculated, considering two possible mechanisms for this secondary reaction. The activation energies for the reactions of the two alcohols were found to be similar, which is in agreement with the multiplet theory of catalysis.

  4. 4.

    The energies of the bonds of H, C, and O atoms with the catalytically active centers of vanadium trioxide were determined.
