Metal — hyper-cross-linked polystyrene (HCP) composites active in the hydrogenation of
unsaturated hydrocarbons were obtained by impregnation of HCP with palladium and rhodium
compounds in supercritical carbon dioxide (SC-CO₂) followed by their reduction to the
metallic state with molecular hydrogen. The influence of the conditions for the preparation of
composites on their activity and selectivity in the hydrogenation of diphenylacetylene (DFA)
was evaluated. The adsorption of palladium hexafluoroacetylacetonate on HCP from the SCCO₂
medium was studied for the first time using supercritical fluid chromatography; it is
shown that the adsorption equilibrium is described by the Langmuir equation.
