Selective Hydrogenation With Copper Catalysts: II. Kinetics
To explain the unusually high selectivity of copper catalysts toward linolenate, model compounds were hydrogenated (150 C and atmospheric pressure) and the reaction products analyzed. Products varied depending upon location of the double bonds. Monoenes were not reduced by copper chromite except when the double bond was next to a carboxyl group. Dienes with isolated double bonds also were not r...
متن کاملHigh-performance supported catalysts with an ionic liquid layer for the selective hydrogenation of acetylene.
Pd-Ag shell catalysts impregnated with two different ionic liquids show considerable improvements both in ethylene selectivity and reduced ethane formation in the selective hydrogenation of acetylene under tail-end conditions.
متن کاملTiO2 supported Pd@Ag as highly selective catalysts for hydrogenation of acetylene in excess ethylene.
A novel TiO2 supported core-shell (Pd@Ag) bimetallic catalyst was fabricated via the sequential photodeposition method. The Ag shell effectively blocks the high coordination sites on the Pd core, and therefore pronouncedly enhances the ethylene selectivity for the catalytic hydrogenation of acetylene in excess ethylene.
متن کاملSelective Hydrogenation With Copper Catalysts: 1. Isolation and Identification of Isomers Formed During Hydrogenation of Linolenate
Methyl linolenate was hydrogenated with 1050 copper chromite catalyst at 150 C and atmospheric hydrogen pressure. The product was separated into monoene, diene and triene fractions by countercurrent distribution. These fractions were further separated into "arious geometrical isomers. The double bond location in the "arious fractions was determined b" reductiw ozonolysis. Double bonus in both c...
متن کاملSelective Hydrogenation of Acetylene over Palladium in Ultra High Vacuum
Under ultra-high-vacuum conditions, precoverage of a palladium(ll1) surface with hydrogen does not affect either the kinetics or the extent of acetylene uptake at 175 K. The subsequent reactive behavior of the system is however radically altered. Benzene formation is strongly suppressed, the transformation of adsorbed acetylene to another species (@-phase) is enhanced, and the yield of ethylene...
