The hydrogenating of carbon-carbon double bond in a molecule of sodium maleate over a partially deactivated catalysts based on nickel in a water solution at atmospheric pressure was investigated. Kinetic regularities of the investigated processes were obtained. It was found that sulfide additives lead to the decrease in an order of the reaction for both skeletal and supported nickel catalysts, however, the correlation of activity versus the amounts of sulfur introduced is complex and independent on the amount of active metal on the catalyst surface. We proposed the method for the synthesis of a supported nickel catalyst resistant to oxidation with atmospheric oxygen and an activity of the one is more than twice better then activity of Raney nickel. The stability of the nickel catalyst (Raney nickel and nickel supported on silica) in the presence of sulfide ions impurities in the reaction system was shown. It was found that the supported nickel catalyst has a much higher resistance to deactivation than the skeletal catalyst. The role of the support at the adsorption of sulfide from solution during deactivation of the investigated catalysts was demonstrated. It was suggested that the higher stability of the supported catalyst for deactivation is due to the sorption of the catalytic poison by silica gel. It is suggested the possibility of adjusting the selectivity of the catalyst deactivation character without changing the nature of the solvent. It was presented the possibility of purposeful variation in a wide range of adsorption properties of the active metal surface relative to the reactants, which makes possible to develop approaches to the synthesis of catalysts with given parameters of activity and selectivity relative to certain classes of organic compounds.Forcitation:Afineevskii A.V., Prozorov D.A., Osadchaya T.Yu., Sukhachev Ya.P., Lukin M.V.
