The hydrogenation of aromatic hydrocarbon compounds derived of hydrocarbon fuels is crucial to avoid the current environment pollution, harmful to human health. Also, the hydrogenated products can be used as chem. intermediates, additives, and in other chem. processes. The search of efficient and cost-effective catalysts for the hydrogenation of aromatic hydrocarbon compounds is a current challenge in the industrial and scientific community. In this study, trimetallic unsupported MMoW (M = Fe, Co, Ni, and Cu) sulfide catalysts were synthesized and tested in the liquid-phase biphenyl (BP) hydrogenation at 300 °C and 5.5 MPa of H2 pressure. The catalysts were characterized by XRD, SEM-EDX, TEM-SAED and adsorption-desorption of N2. The presence of NiS, CoSx, MoFe2S4, Cu9S5 crystalline sulfide phases together with Mo(W)S2 crystalline sulfide phase, as well as the crystallite size and the surface area, influenced the catalytic performance. Ni-based catalysts were the most active in the BP hydrogenation. A BP conversion value of ∼99% of biphenyl and selectivity of 52% towards cyclohexylbenzene (CHB) and 47% towards bicyclohexyl were reached using NiMoWS catalyst. The presence of NiS crystals, stacked curve-shape Mo(W)S2 crystalline phases and larger surface area values increased the catalytic activity using NiMoWS catalysts. The experimental process involved the reaction of 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Computed Properties of C4H4INO2)
1-Iodopyrrolidine-2,5-dione(cas: 516-12-1) is used in the preparation of vinyl sulfones from olefins and benzenesulfinic acid. It acts as a source for I+ and involved in Hunsdiecker reactions for the conversion of cinnamic acids, and propiolic acids to the corresponding alfa-halostyrenes and 1-halo-1-alkynes respectively.
