1. 1. It has been established that, in the absence of hydrogen in the gaseous phase (in nitrogen atmosphere), skeletal Ni is active in the “irreversible catalysis” reaction of cyclohexene. 2. 2. In addition to disproportionation, hydrogenation of cyclohexene takes place to a negligible extent by hydrogen adsorbed on a skeletal catalyst. Takes ratio of the rates of disproportionation and hydrogenation depends on the amount of catalyst. 3. 3. During hydrogenation of cyclohexene by hydrogen diluted with nitrogen, the relative rates of the two reactions in the process depend on partial hyrogen pressure in the gaseous phase. |
