This book was released on 2012-12-06 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Born and initially developed in various industrial laboratories, mainly in U.S.A. and Gennany, homogeneous phase catalytic carbon monoxide hydrogenation and alcohols and their derivatives carbonylation and homologation, have generally been considered and reviewed separately in the course of their 40 years history without concern for common aspects in the chemical transfonnations and in catalysis. Thanks to researchers of Japanese companies participating in the National C 1 Chemistry Project (1980-1987) the scientific and technical approaches in this field have been unified and applied in parallel, in the light of some common aspects of the chemical reactions and mechanisms. Now, at a moment when research seems becahned, a general presentation and discussion of the most recent topics might be an useful basis for further development of this chemistry. To delimit and simplify the discussion of the chemical aspects and the nature of the catalysts involved, the present review is limited to reactions employing homogeneous metal complexes for the direct conversion of syngas to oxygenates and to the hydrocarbonylation of these last to homologous derivatives. Since the previous practically contemporary reviews by Dombek [in Adv. Organomet. Chern. (1983)] on CO hydrogenation and by the present authors [in Asp.Homog.Catal.(Reidel Pu.l984)] on alcohol homologation fully cover the literature up to 1982, here we mainly refer to work done after 1982, and consider the cited reviews as covering the historical development of research in the 1940- 1980 period.

Download or read book The Effects of Potassium on Carbon Monoxide Methanation Over Supported Rhodium Films written by C. H. Dai and published by . This book was released on 1986 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reaction of hydrogen with carbon monoxide over Rh/Al2O3 and Rh/TiO2 catalytic films, some of which contained potassium as an additive, has been investigated. The presence of potassium caused the usual gem dicarbonyl and linear CO species on supported rhodium to dissociate at lower temperature than for catalysts containing no potassium. On the other hand, the bridged carbonyl species was significantly enhanced by the presence of potassium. The Rh/TiO2 films to which potassium was added catalyzed the production of significant amounts of acetone and acetaldehyde as oxigenated products. It is likely that the bridged carbonyl species is the precursor to oxygenated products.

This book was released on 2012-12-06 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some years ago, I agreed to contribute a volume to the Academic Press 'Organo metallic Chemistry' series - the metals to be covered were rhodium and iridium. Initially, my plan was to discuss both the fundamental organometallic chemistry and applications in organic synthesis. When the first draft of the manuscript was complete, it was apparent that I had exceeded my allowance of pages by a huge amount. It was then that I decided that the catalysis section warranted separate treatment. I am grateful to Reidel for agreeing to publish this volume on Homogeneous Catalysis with Compounds of Rhodium and Iridium as part of their 'Catalysis by Metal Complexes' series. The material I had for the original Academic Press project covered the litera ture to the end of 1978. I decided to update this to the end of 1982 with a few key references from 1983. It is some measure of the rate of progress in this field that the number of references almost doubled during this revision.

Download or read book An Infrared Study of the Oxidation of Carbon Monoxide Over Supported Rhodium Catalysts written by C. H. Dai and published by . This book was released on 1985 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reaction of carbon monoxide and oxygen over supported rhodium films has been studied using infrared spectroscopy. The focus of work was the reactivity of the various CO/Rh/X (X=Al2O3, SiO2, TiO2) surface states for supported catalysts having high and low Rh loading. Under the reaction conditions the 'linear CO' species was the most stable toward oxidation, but this could have been a result of an oxidized Rh surface. A new CO/Rh surface species has been proposed which exhibits an infrared band at 2000/cm for a 0.5% Rh/TiO2 film. This species is believed to be a bridged carbonyl between Rh+1 and the TiO2 support. Originator-supplied keywords include: Infrared spectroscopy, and Carbon dioxide.

Available in PDF, EPUB and Kindle. Book excerpt: A mechanism is proposed for the formation of methanol and other oxygenated organic products from carbon monoxide and hydrogen over metal oxide catalysts. These products are formed via the associative adsorption of carbon monoxide on the oxygen of the metal oxide surface, followed by reduction with metal activated hydrogen. Carbon dioxide is dissociated to chemisorbed CO and O. This explains why over-reduction of methanol catalysts results in the formation of hydrocarbons rather than methanol. The mechanism of methanol formation with combined heterogeneous nickel boride and homogeneous molybdenum hexacarbonyl is postulated. (JSR).

Download or read book Direct Observation of the Kinetically Relevant Site of CO Hydrogenation on Supported Ru Catalyst at 700 K by Time-Resolved FT-IR Spectroscopy written by and published by . This book was released on 2008 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: Time-resolved FT-IR spectra of carbon monoxide hydrogenation over alumina-supported ruthenium particles were recorded on themillisecond time scale at 700 K using pulsed release of CO and a continuous flow of H2/N2 (ratio 0.067 or 0.15, 1 atm total pressure). Adsorbed carbon monoxide was detected along with gas phase products methane (3016 and 1306 cm-1), water (1900 +- 1300 cm-1), and carbon dioxide (2348 cm-1). Aside from adsorbed CO, no other surface species were observed. The rate of formation of methane is 2.5 +- 0.4 s-1 and coincides with the rate of carbon dioxide growth (3.4 +- 0.6 s-1), thus indicating that CH4 and CO2 originate from a common intermediate. The broad band of adsorbed carbon monoxide has a maximum at 2010 cm-1 at early times (36 ms) that shifts gradually to 1960 cm-1 over a period of 3 s as a result of the decreasing surface concentration of CO. Kinetic analysis of the adsorbed carbon monoxide reveals that surface sites absorbing at the high frequency end of the infrared band are temporally linked to gas phase product growth. Specifically, a (linear) CO site at 2026 cm-1 decays with a rate constant of 2.9 +- 0.1 s-1, which coincides with the rise constant of CH4. This demonstrates that the linear CO site at 2026 cm-1 is the kinetically most relevant one for the rate-determining CO dissociation step under reaction conditions at 700 K.
