Chemoselective three-phase hydrogenation of an Ombrabulin nitro-stilbene intermediate in a continuous-flow mobile platform
Lioubov Kiwi, Charline Berguerand
The chemoselective three-phase hydrogenation of an Ombrabulinintermediate based on a nitro-stilbene framework was used as a case study for the formation of the primary amine without affecting the double bond. Two catalysts were tested: Pt nanoparticles sup ...
Elsevier Science Sa2017Continuously operated falling film microreactor for selective hydrogenation of carbon-carbon triple bonds
Lioubov Kiwi, Charline Berguerand
Despite significant advances in the fabrication and applications of microreactors for production of chemicals, their use for catalytic reactions remains a challenge, especially in fine chemical synthesis where the selectivity towards the desired product is ...
Elsevier2016Pt-Zn nanoparticles supported on porous polymeric matrix for selective 3-nitrostyrene hydrogenation
Lioubov Kiwi, Fernando Cardenas Lizana, Charline Berguerand, Artur Yarulin, Irina Prokopyeva
We report the promoting effect of Zn on performance of Pt-based catalyst in liquid-phase hydrogenation of 3-nitrostyrene (3-NS) to 3-vinylaniline (3-VA). Bimetallic Pt-Zn nanoparticles (NPs) were prepared within the hypercross-linked polystyrene (HPS) supp ...
Elsevier2015Chemoselective Liquid Phase Hydrogenation of 3-Nitrostyrene over Pt Nanoparticles: Synergy with ZnO Support
Lioubov Kiwi, Fernando Cardenas Lizana, Charline Berguerand, Artur Yarulin
Hydrogenation of 3-nitrostyrene was performed at T = 348 K and 10 bar over platinum nanopartides supported on several metal oxides. Pt/Al2O3 and Pt/C catalysts exhibited high activity giving 3-ethylaniline as the only product, while Pt/ZnO displayed high s ...
American Chemical Society2015Increasing Pt selectivity to vinylaniline by alloying with Zn via reactive metal-support interaction
Lioubov Kiwi, Charline Berguerand, Artur Yarulin
The promoting effect of Zn on Pt-based catalyst was studied for the liquid-phase hydrogenation of 3-nitrostyrene (3-NS). The monodispersed Pt nanoparticles (ca. 2.3 nm) supported on ZnO catalyzed the target 3-vinylaniline (3-VA) formation (S3-VA = 97% at X ...
Elsevier2015Size-Controlled Pd Nanoparticles in 2-Butyne-1,4-diol Hydrogenation: Support Effect and Kinetics Study
Lioubov Kiwi, Fernando Cardenas Lizana, Charline Berguerand
Structured catalyst has been developed for C–C triple bond three-phase hydrogenation. The sintered metal fiber (SMF) coated by different oxides served as support for monodispersed Pd nanoparticles (6.4 ± 0.5 nm). The effect of acid–base properties and redu ...
Amer Chemical Soc2014Life Cycle Analysis within Pharmaceutical Process Optimization and Intensification: Case Study of Active Pharmaceutical Ingredient Production
Lioubov Kiwi, Charline Berguerand
As the demand for new drugs is rising, the pharmaceutical industry faces the quest of shortening development time, and thus, reducing the time to market. Environmental aspects typically still play a minor role within the early phase of process development. ...
Wiley-VCH Verlag Berlin2014Intensification of slow reversible chemical transformation: carboxylation of resorcinol as a case study
Lioubov Kiwi, Charline Berguerand, Anne-Laure Dessimoz
Conjugated kinetic and thermodynamic modeling is suggested as a suitable approach to identify a novel process window (NPW) for the intensification of slow reversible reactions. The aqueous Kolbe-Schmitt synthesis of beta-resorcylic acid is taken as a model ...
De Gruyter2013Chemoselective hydrogenation of nitroarenes: Boosting nanoparticle efficiency by confinement within highly porous polymeric framework
Lioubov Kiwi, Fernando Cardenas Lizana, Charline Berguerand
We report for the first time 99.9% yield of aminocompounds and high TOFs (up to 61 s(-1)) in the liquid-phase hydrogenation of several para-substituted (-OH, -OCH3, -CH3, -H, -Br, -Cl, -COOH and -NO2) nitroaromatics over quasi-monodispersed (ca. 3.3 nm fro ...
Elsevier2013Kinetic and thermodynamic study of the aqueous Kolbe–Schmitt synthesis of beta-resorcylic acid
Albert Renken, Lioubov Kiwi, Charline Berguerand, Anne-Laure Dessimoz
Detailed thermodynamic and kinetic study of the aqueous Kolbe-Schmitt synthesis of beta-resorcylic acid has been carried out in a laboratory-scale batch reactor operated under ambient pressure. The dependence of the conversion on partial pressure of carbon ...
