Polycrystalline metallic copper nanoparticle samples with the average particle sizes ranging from 53 to 80 nm were controllably prepared by the wet chem. reduction of copper hydroxide with hydrazine hydrate at 50掳C for 1-4 h. The small-sized copper nanoparticles exhibited a higher catalytic activity than the large-sized ones in the hydrogenation of 1-nitroanthraquinone with gaseous hydrogen to 1-aminoanthraquinone at the reaction temperatures of 180-220掳C. When the hydrogenation reaction was conducted at 200掳C and H2 pressures of 0.3-0.7 MPa, the copper nanoparticles with the average particle size of 53 nm exhibited the selectivity of 1-aminoanthraquinone of above 88% at the conversion of 1-nitroanthraquinone of above 95%. A power type reaction kinetics equation well fit the exptl. data and the simulated activation energy is 51 kJ mol-1. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Related Products of 20427-59-2).
Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. The evolution of transition metal catalysts has attained a stage of civilization that authorizes for an extensive scope of chemical bonds formation partners to be combined efficiently. Copper nanoparticles can also catalyze the coupling reaction of nitrogen-containing nucleophiles, phenols, thiols, xanthogenates, selenium ruthenium nucleophiles and the like.Related Products of 20427-59-2
