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 ...

Removal of pharmaceuticals in pre-denitrifying MBBR Influence of organic substrate availability in single- and three-stage configurations

Luca Loreggian

Due to the limited efficiency of conventional biological treatment, innovative solutions are being explored to improve the removal of trace organic chemicals in wastewater. Controlling biomass exposure to growth substrate represents an appealing option for ...

Racemization of undesired enantiomers: Immobilization of mandelate racemase and application in a fixed bed reactor

Production of optically pure products can be based on simple unselective synthesis of racemic mixtures combined with a subsequent separation of the enantiomers; however, this approach suffers from a 50% yield limitation which can be overcome by racemizatio ...

A comparison of orbitally-shaken and stirred-tank bioreactors: pH modulation and bioreactor type affect CHO cell growth and protein glycosylation

Florian Maria Wurm, David Hacker, Lucia Baldi Unser, Marc Moniatte, Dominique Terry Monteil Jr, Valentin Juvet

Orbitally shaken bioreactors (OSRs) support the suspension cultivation of animal cells at volumetric scales up to 200 L and are a potential alternative to stirred-tank bioreactors (STRs) due to their rapid and homogeneous mixing and high oxygen transfer ra ...

Identification of Multiphase Reaction Systems with Instantaneous Equilibria

Dominique Bonvin, Julien Léo Billeter, Sriniketh Srinivasan

The identification of kinetic models for multiphase reaction systems is complex due to the simultaneous effect of chemical reactions and mass transfers. The extentbased incremental approach simplifies the modeling task by transforming the reaction system i ...

American Chemical Society2016

The concept of variant and invariant states has been developed to decouple the various dynamic effects in reaction systems. The aim of the project is to explore the applications of this concept to control of reaction systems. The concept of reaction varian ...

Control of Reaction Systems via Rate Estimation and Feedback Linearization

Dominique Bonvin, Julien Léo Billeter, Diogo Filipe Mateus Rodrigues

Abstract of the conference paper The kinetic identification of chemical reaction systems often represents a time-consuming and complex task. This contribution presents an approach that uses rate estimation and feedback linearization to implement ...
