Selective Liquid-Phase Semihydrogenation of Functionalized Acetylenes and Propargylic Alcohols with Silica-Supported Bimetallic Palladium−Copper Catalysts†

Silica-supported copper catalysts were prepared by different methods, and Cu/SiO2 prepared by the urea-assisted gel method was modified with co-catalyst platinum to obtain Cu-Pt/SiO2 bimetallic catalysts. The prepared catalysts were characterized by nitrogen adsorption–desorption, XRD, TEM, hydrogen chemisorption, ammonia gas chemisorption, and X-ray photoelectron spectroscopy. The characterization results show that the modification of platinum is helpful to the reduction and dispersion of copper species, which increase the hydrogen uptake quantity and metal surface area. The 30%Cu–3.0%Pt/SiO2-6 presents the best catalytic performance in liquid-phase diethyl oxalate hydrogenation; it gives 77.32% conversion of diethyl oxalate and 94.37% selectivity to the main products under 473 K and 3.0 MPa for 4 h. A possible reaction route was also proposed.

In the presented review the results of studies devoted to the selective hydrogenation of acetylene to ethylene over bimetallic palladium-containing catalysts are systematized. General regularities and peculiarities of the catalysts action in gas-phase hydrogenation of traces of acetylene in the acetylene-ethylene mixture obtained by pyrolysis of petroleum raw materials, as well as in the process of liquid-phase hydrogenation of mixtures enriched with acetylene and hydrogen are analyzed. The advantages of obtaining ethylene by hydrogenation of acetylene in the liquid phase are shown and ways of increasing the selectivity of this process are considered.
