The principal objective of this thesis is the development of a palladium catalyst supported on woven fabrics of activated carbon fibers (ACF) for the reactions of hydrogenations in liquid phase and the design of multiphase reactors using the characteristic ...
This thesis deals with a laboratory study of heterogeneous reactions involving bromine and chlorine containing reservoir species on alkali salt substrates which are relevant to the marine boundary layer, and on ice substrates which are relevant to the lowe ...
Methanol dehydrogenation to formaldehyde was conducted in a fixed-bed flow reactor with sodium carbonate catalyst mixed with active carbons or transition metals. The additives promoted the reaction rate at 880-970 K without modifying formaldehyde selectivi ...
Whereas pentylsodium in pentane mainly promotes a hydrogen/metal exchange reaction at the m- and p-position of phenylcyclopropane (I), both BuLi-KOCMe3 and Me3SiCH2K in THF convert I into 1-phenylcyclopropylpotassium. The latter adds smoothly to ethylene a ...
A straightforward sequence of reactions allowed the conversion of D-(+)-mannose and D-(+)-ribono-1,4-lactone into erythro-(2S,3R)- and threo-(2S,3S)-sphingosine, resp. [on SciFinder (R)] ...
The solubility of hydrogen and the corresponding Henry coefficients for 11 ionic liquids have been determined in situ at 100 atm H-2 pressure and are much lower than expected; attempts to correlate the solubility of hydrogen in the ionic liquids with the r ...
Among other things, the present thesis work aimed at a rational and maximal structure proliferation. Simple arenes or heteroarenes were functionalized regioselectively through organometallic intermediates, which then may be combined with any electrophile t ...
The measurements obtained were used to investigates the methanol synthesis reaction from pure carbon dioxide and hydrogen over binary (CuO/ZrO2) and ternary supported catalysts (CuO/ZnO/Al2O3). A comparison of different catalysts is presented. The influenc ...
The aim of this study is to identify the reaction mechanism of methanol dehydrogenation on sodium carbonate catalyst. Quantitative analyses of the products of methanol dehydrogenation on sodium carbonate catalyst at 963 K indicate that methane is formed in ...
Methanol dehydrogenation to formaldehyde was operated in a continuous fixed-bed reactor with external recycling in the presence of sodium carbonate catalyst supported on active carbon. Due to the importance of gas phase decompns. of methanol and mainly for ...
