Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Interspecies competitive effects on the degradation of two alkyl halides (1-bromo-2-chloroethane, BCA, and 1,1,2-trichloroethane, 1,1,2-TCA) and three vinyl halides (trichloroethylene, TCE; cis-dichloroethylene, cis-DCE; and trans-dichloroethylene, trans-D ...
This book represents first non-edited book on the subject of metal catalysed reactions in ionic liquids and covers the literature from its origins until early 2005. Following a general introduction to the field of biphasic/mutliphasic catalysis, the synthe ...
Ethylene oxide was prepd. by the oxidn. of C2H4 by O over a Ag catalyst under non-stationary conditions, with the amt. of C2H4 and/or O being varied periodically. Thus, with C2H4 being varied from 0 to 12 mole % for 20 h at 10% C2H4 conversion, an increase ...
There is a wide class of electrochemical systems which present a sudden transition from a high to a low reaction rate region in function of an external parameter. This sudden transition is accompanied by the growth of a surface structure responsible for de ...
Studies on the sp-sp intermolecular coupling reactions with the palladium water-soluble catalyst prepared in situ from palladium(II) acetate and sulfonated triphenylphosphine P(C6H4-m-SO3Na)(3) (TPPTS) in a homogeneous acetonitrile-water system, without Cu ...
The electrochemical activation of ethylene oxidation was studied over rhodium catalysts of different thickness (40, 100 and 160 nm) sputtered on top of a thin layer of TiO2 deposited on YSZ. The strong relationship between catalytic activity and oxidation ...
Toluene oxidn. over Pb/Li/MgO is investigated in a tubular fixed bed reactor at low conversions. A periodic process alternating toluene oxidn. in absence of oxygen in the feed and regeneration of the catalyst by oxygen presents important changes in product ...
Four galactofuranose-containing disaccharides have been prepared utilising various thioimidates [Galf-SC(NR)XR′] and suitably protected acceptors as key precursors. We observed that the efficiency of the coupling reactions was particularly dependent on the ...
A series of relatively low-cost ionic liquids, based on the N-butyronitrile pyridinium cation C(3)CNpy, designed to improve catalyst retention, have been prepared and evaluated in Suzuki and Stille coupling reactions. Depending on the nature of the an ...
