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. 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. 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. At temperatures of 400-500°, MoO3 and MoO2 produce dehydrogenation of cyclohexane to a slight extent. 1960 Consultants Bureau Enterprises, Inc.
