For the case of a model reaction of nitrobenzene hydrogenation in the presence of the palladium-containing anionite AV-17-8, certain features of using metal-containing polymers as catalysts for reactions of organic and petrochemical synthesis have been shown. In particular a study has been made of the influence of the metal content of the polymer, the particle size of the support and its swelling in organic solvents on the hydrogenation rate of nitrobenzene.
