Реферат:
A comparative catalytic study of Pd-Ag bimetallic catalysts and the commercial Lindlar catalyst (Pd-Pb/CaCO3) has been carried out in the hydrogenation of phenylacetylene (PA) and diphenylacetylene (DPA). The Pd-Ag catalysts have been prepared using the heterobimetallic complex PdAg2(OAc)(4)(HOAc)(4) supported on MgAl2O4 and aluminas (alpha-Al2O3 and gamma-Al2O3). Physicochemical studies have demonstrated that the reduction of supported Pd-Ag complex with hydrogen results in homogeneous Pd-Ag nanoparticles. Equal in selectivity to the Lindlar catalyst, the Pd-Ag catalysts are more active in DPA hydrogenation. The synthesized Pd-Ag catalysts are active and selective in PA hydrogenation as well, but the unfavorable ratio of the rates of the first and second stages of the process makes it difficult to kinetically control the reaction. The most promising results have been obtained for the Pd-Ag-2/alpha-Al2O3 catalyst. Although this catalyst is less active, it is very selective and allows efficient kinetic control of the process to be carried out owing to the fact that, with this catalyst, the rate of hydrogenation of the resulting styrene is much lower than the rate of hydrogenation of the initial PA.
