Summary

  1. 1.

    MoO3, obtained by decomposition of ammonium molybdate in a stream of nitrogen at 500°, is a catalyst for the dehydration of alcohols. The activation energy for isopropyl alcohol is 13.9 kcal/mole.

     
  2. 2.

    MoO2, obtained by reduction of MoO3 with molecular hydrogen at 500°, is a catalyst for the dehydrogenation of alcohols. The activation energy for isopropyl alcohol equals 12.5 kcal/mole.

     
  3. 3.

    MoO2 chemisorbs nitrogen at 500° and is thus completely deactivated as regards dehydrogenation of alcohol. Treatment of the inactive catalyst with hydrogen at 500° partially restores the activity of the catalyst as a result of desorption of the nitrogen as ammonia.

     
  4. 4.

    At temperatures of 400–500°, MoO3 and MoO2 produce dehydrogenation of cyclohexane to a slight extent.
