So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Belle, Alessandro; Kusada, Kohei; Kitagawa, Hiroshi; Perosa, Alvise; Castoldi, Lidia; Polidoro, Daniele; Selva, Maurizio researched the compound: Ruthenium(III) chloride xhydrate( cas:14898-67-0 ).Formula: Cl3H2ORu.They published the article 《Carbon-supported WOx-Ru-based catalysts for the selective hydrogenolysis of glycerol to 1,2-propanediol》 about this compound( cas:14898-67-0 ) in Catalysis Science & Technology. Keywords: glycerol propanediol carbon tungsten oxide ruthenium catalyst hydrogenolysis. We’ll tell you more about this compound (cas:14898-67-0).
New C-supported bimetallic Ru-WOx catalysts, prepared by co-impregnation of RuCl3 and Na2WO4, proved highly efficient for the liquid-phase hydrogenolysis of aqueous glycerol into 1,2-propanediol (1,2-PDO). The tuning of the catalyst composition and major reaction parameters, specifically operating at 150°C, 5 bar H2, and Ru : W = 4 : 1 mol/mol, allowed conversion of glycerol and 1,2-PDO selectivity of 73≥99% and 88-98%, resp., with a carbon loss of <5%. Ru-WOx/C offered a steady performance for up to 7 subsequent recycles during which leaching of Ru was negligible, while loss of W decreased from an initial 5 weight% (1st run) to 0.1 weight% after 5 runs. The catalyst characterization, in particular EDX anal. and high-resolution TEM images, confirmed a uniform dispersion of Ru and W on the C surface with the presence of small Ru nanoparticles (below 2 nm) and randomly aggregated dots which could be ascribed to WOx clusters of size below 100 nm. Based on both the Bronsted and the Lewis acidity of WOx species, a reaction mechanism was proposed through an initial dehydration of glycerol followed by a Ru-catalyzed hydrogenation process. I hope my short article helps more people learn about this compound(Ruthenium(III) chloride xhydrate)Formula: Cl3H2ORu. Apart from the compound(14898-67-0), you can read my other articles to know other related compounds.
