Environmentally Benign Transformations of Monoterpenes and Monoterpenoids in Supercritical Fluids
TL;DR: In this paper, a review of all types of transformations of monoterpenes and their derivatives in supercritical fluids is presented, including the results obtained by the authors and literature data.
Heterogeneous Catalytic Hydrogenation of Polymers Facilitated by Supercritical Carbon Dioxide
TL;DR: Xu et al. as discussed by the authors used 5%Pd/BaSO4 as the catalyst for polystyrene (PS) hydrogenation in decahydronaphthalene (DHN).
Journal ArticleDOI
Critical Temperatures and Pressures of the Reacting Mixture in the Acylation of Anisole with Acetic Anhydride
TL;DR: In this paper, the supercritical reaction conditions of anisole acylation with acetic anhydride using certain solvents such as carbon dioxide or propane were determined using a high-pressure viewing cell.
Journal ArticleDOI
Catalytic methyl esterification of colophony over ZnO/SFCCR with subcritical CO2: catalytic performance, reaction pathway and kinetics.
TL;DR: An experimental set-up involving a new injection technique was designed to promote the heterogeneous methyl esterification, and the subcritical CO2 played a role in auxiliary acid catalysis, increasing the lifespan of ZnO/SFCCR and reducing the viscosity of the system to promote gas–liquid mass transfer.
Journal ArticleDOI
Hydrothermal liquefaction of biomass with molybdenum, aluminum, cobalt metal powder catalysts and evaluation of wastewater by fungus cultivation
TL;DR: In this article , the Ammi visnaga plant was liquefied in the presence of Mo, Al and Co metal powder catalysts and without catalyst, and the highest liquid product yield was determined as 42.31% in the experiment without catalyst and 39.42% with Mo catalyst at 300 °C.

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.
