This work covers homogeneous and biphasic catalysis in ionic liquids and water. The work presented herein is divided into two major parts: catalytic hydrogenation and catalytic hydroformylation. The first part also serves as an introduction to catalysis in ...
Carbon-carbon bond cleavage of 1,2-diphenyl-ethanes in CH3OH-H2SO4-H2O electrolyte on a boron-doped diamond (BDD) electrode has been investigated electrode using 1,2-di-(p-tert-butylphenyl)-ethane and 1,2-dimethoxy-1,2-di-(p-tert-butylphenyl)-ethane as mod ...
Gold nanoparticles of 2–5 nm supported on woven fabrics of activated carbon fibers (ACF) were effective during CO oxidation at room temperature. To obtain a high metal dispersion, Au was deposited on ACF from aqueous solution of ethylenediamine complex [Au ...
Although there are many conceivable ways to functionalize, and specifically carboxylate, 2-chloro-4-(trifluoromethyl)pyridine optionally at all three vacant positions, it is more straightforward to prep. only 2-chloro-4-(trifluoromethyl)pyridine-3-carboxyl ...
This work reports the hydrogenation of carbon dioxide/inorganic carbonate salts to formic acid/formate in two phase systems comprising an ionic phase, in which the catalyst is immobilized, and an aqueous phase in which the carbonates and formate are confin ...
Aq. solns. of formic acid were exptl. investigated in a modified sweeping gas membrane distn. (SGMD) configuration. A thermostated sweeping gas was used in order to enhance the mass transfer performance. A new tubular module was designed and built for this ...
Pure and K-doped vanadia/titania prepared by different methods have been studied in order to elucidate the role of vanadia species (monomeric, polymeric, bulk) in catalytic toluene partial oxidation. The ratio of different vanadia species was controlled by ...
Thin boron-doped diamond films were prepd. by HF CVD (hot filament chem. vapor deposition technique) on conductive p-Si substrate (Si/diamond). The morphol. of these Si/diamond electrodes was investigated by SEM and Raman spectroscopy. The electrochem. beh ...
The gas phase species produced in rf plasmas of hexamethyldisiloxane (HMDSO), Si2O(CH3)(6), diluted with oxygen, have been investigated. The complementarity of Fourier transform infrared absorption spectroscopy and mass spectrometry allows the determinatio ...
The homogeneous hydrogenation of carbon dioxide into formate anion has been investigated in aqueous solution, using water soluble ruthenium(II)-phosphine (meta-monosulphonated triphenylphosphine, TPPMS; and 1,3,5-triaza-7-phosphaadamantane, PTA) complexes ...
