Three-Phase Catalytic Hydrogenation of a Functionalized Alkyne: Mass Transfer and Kinetic Studies with in Situ Hydrogen Monitoring

Albert Renken, Lioubov Kiwi, Martin Grasemann

Systematic studies of mass transfer interactions with intrinsic reaction kinetics were performed for the threephase selective hydrogenation of 2-methyl-3-butyn-2-ol (MBY) to 2-methyl-3-buten-2-ol (MBE) over a modified Pd/CaC

Palladium Nanoparticle Size Effect in 1-Hexyne Selective Hydrogenation

Albert Renken, Lioubov Kiwi

The structure sensitivity of a liquid-phase 1-hexyne hydrogenation was studied using monodispersed nonsupported Pd nanoparticles of 6, 8, 11, 13, and 14 nm diameter. The particles were prepared via a reverse microemulsion water/AOT/isooctane. The size was ...

The Effective Rank: A Measure of Effective Dimensionality

Martin Vetterli, Olivier Roy

Many signal processing algorithms include numerical problems where the solution is obtained by adjusting the value of parameters such that a specific matrix exhibits rank deficiency. Since rank minimization is generally not practicable owing to its integer ...

Switching the Mechanism of Catalyst Activation by Ionic Liquids

Paul Joseph Dyson, Corinne Daguenet

In ionic liqs. (ILs), the activation of a ruthenium(II) catalyst precursor occurs via an unexpected mechanism, which is different from the activation mechanism that takes place in water. The effectiveness of a biphasic catalytic hydrogenation reaction usin ...

Catalytic hydrogenation of alkenes under biphasic conditions

Corinne Daguenet

Ruthenium(II)-arene diphosphine complexes are shown to be effective precursors for the catalytic hydrogenation of the C=C bond in an aqueous biphase using molecular hydrogen as the hydrogen source. A mechanistic study performed in water, utilizing high gas ...

Biphasic Hydrosilylation in Ionic Liquids: A Process Set for Industrial Implementation

Paul Joseph Dyson, Gabor Laurenczy, Dongbin Zhao

The biphasic hydrosilylation of 1-hexadecene with siloxane B9800 in a range of ionic liqs. is reported. Of the ionic liqs. tested, [C4py][BF4] and [C4-3-pic][BF4] offer the optimum compromise between activity and ...

Solvent-Free Selective Hydrogenation of 2-Butyne-1,4-diol over Structured Palladium Catalyst

Albert Renken, Lioubov Kiwi, Eric Joannet

Hydrogenation of 2-butyne-1,4-diol catalyzed by Pd nanoparticles on activated carbon fibers (ACFs) was studied. The ACF support in the form of woven fabrics provides the basis for structured catalytic fixed beds. In the present study, this catalyst was int ...

Searching for molecular arene hydrogenation catalysis in ionic liquids

Paul Joseph Dyson

Arene hydrogenation by homogeneous catalysts is a highly controversial area of research, with many of the mononuclear complexes shown to catalyse the reaction, being found to be pre-catalysts to nanoparticles, on closer examination. The solvent properties ...
