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.
