Journal ArticleDOI
Hydrogenation of nitrile in supercritical carbon dioxide : a tunable approach to amine selectivity
Maya Chatterjee,Hajime Kawanami,Masahiro Sato,Takayuki Ishizaka,Toshirou Yokoyama,Suzuki Toshishige +5 more
TL;DR: In this article, the use of supercritical carbon dioxide (scCO2) on the hydrogenation of benzonitrile was investigated over Pd and other metal catalysts, and the results confirmed that the presence of CO2 is mandatory for the formation of benzylamine with high selectivity.
Journal ArticleDOI
High pressure in situ x-ray absorption spectroscopy cell for studying simultaneously the liquid phase and the solid/liquid interface
Jan-Dierk Grunwaldt,Michael Ramin,Markus Rohr,Alexej Michailovski,Greta R. Patzke,Alfons Baiker +5 more
TL;DR: In this paper, a high pressure in situ x-ray absorption spectroscopy cell with two different path lengths and path positions is presented for studying element-specifically both the liquid phase and the solid/liquid interface at pressures up to 250 bar and temperatures up to 220 °C.
Journal ArticleDOI
Maleic anhydride hydrogenation over Pd/Al2O3 catalyst under supercritical CO2 medium
TL;DR: In this article, a comparison of the supercritical CO2 medium reaction with the conventional hydrogenation in the presence of commonly employed organic solvents is also described, and the use of various co-solvents for CO2 has also been investigated.
Journal ArticleDOI
The role of carbon dioxide in chemoselective hydrogenation of halonitroaromatics over supported noble metal catalysts in supercritical carbon dioxide
TL;DR: Chemoselective hydrogenation of halogenated nitrobenzenes over Pt/C catalysts proceeds effectively in supercritical carbon dioxide (scCO2) to produce halogenation anilines with excellent selectivity.
Journal ArticleDOI
Continuous Enantioselective Hydrogenation of Ethyl Pyruvate in “Supercritical” Ethane: Relation between Phase Behavior and Catalytic Performance
TL;DR: In this article, the phase behavior of an α-ketoester was investigated in a fixed-bed reactor over cinchonidine-modified Pt/Al2O3 using supercritical ethane as a solvent.

Aerogels-Airy Materials: Chemistry, Structure, and Properties.
Nicola Hüsing,Ulrich S. Schubert +1 more
TL;DR: The design of such a filigrane network requires the very careful control of chemical parameters and the reward is an assortment of different property profiles owing to the richness of possible variations.
Journal ArticleDOI
Structures of metal sites of oxidized bovine heart cytochrome c oxidase at 2.8 A
Tomitake Tsukihara,Hiroshi Aoyama,Eiki Yamashita,Takashi Tomizaki,Hiroshi Yamaguchi,Kyoko Shinzawa-Itoh,Ryosuke Nakashima,Rieko Yaono,Shinya Yoshikawa +8 more
TL;DR: The high resolution three-dimensional x-ray structure of the metal sites of bovine heart cytochrome c oxidase is reported, suggesting a dinuclear copper center with an unexpected structure similar to a [2Fe-2S]-type iron-sulfur center.
Journal ArticleDOI
Homogeneous Hydrogenation of Carbon Dioxide
TL;DR: In this article, the simplest and most studied reactions of CO{sub 2} are the catalytic reactions with H{sub 1} in the presence or absence of other reactive species.

Reactions at supercritical conditions: Applications and fundamentals
TL;DR: A review of chemical reactions in and with supercritical fluids can be found in this paper, where the authors discuss both fundamental studies and applications of reactions at supercritical conditions, with focus on work published after 1985.
