Fundamental aspects of the influence of solvent nature on the activity and selectivity of palladium catalysts modified with white phosphorus in hydrogenation of ortho-chloronitrobenzene were determined. The conditions are suggested in which the chemoselectivity of palladium catalysts modified with white phosphorus can be raised to 93-95% with respect to ortho-chloroaniline in the temperature range 30-80°C without accumulation in the reaction system of undesirable products, ortho-chlorophenylhydroxylamine and azo- and azoxychlorobenzene.
