CERTAIN REGULARITIES OF THE CATALYTIC HYDROGENATION OF NITROBENZENE DERIVATIVES ON RANEY NICKEL

Nitrobenzene, m-nitrotoluene, p-nitrotoluene, p-nitrophenol, o-nitrophenol, o-nitroaniline, and p-nitrophenetole were hydrogenated at 20 degrees at hydrogen pressure of 750 mm Hg with Raney nickel used as the catalyst. Kinetic curves and rate constants of the process were taken, and a relationship between the rate constant and the 'solvate chromic effect' was demonstrated. It is stated that the results provide dome confirmation of the assumed presence of a connection between the change in the energy of reaction of molecules of a dissolved substance with the medium and the change in the activation energy of certain reactions.
