Flow Chemistry

Chemical reactions have traditionally been performed in flasks or test tubes.  Increasingly, an alternative approach based on flowing chemical reaction through tubes and pipes until they are complete, has been gaining popularity.  This is due, in part, to the new opportunities it provides for the continuous manufacture of high-value chemicals on scale.  Reactions conducted under flow enable better control of parameters such as temperature and pressure.  They also allowing highly reactive species to be handled safely and effectively, greatly reducing hazards which in turn opens up new modes of reactivity.  Additionally, continuous flow processing can offer advantages for scalability; process intensification and the development of  daisy chain reactions by using the output of one reaction as the input for another.

The LabFact team has a number of active projects in this area, with expertise in flow processing for transformations triggered using heat, light, microwaves and electricity.  Various systems are available including commercial and bespoke instruments.  We also have 3D printer facilities available for the on-demand design/manufacture of miniaturised flow reactors.

Les r√©actions chimiques sont traditionnellement effectu√©es en ballons.¬†¬†Une approche alternative bas√©e sur la r√©action chimique en flux dans des r√©acteurs tubulaires¬†s‚Äôest r√©cemment d√©velopp√©e, offrant de nouvelles possibilit√©s¬†pour la synth√®se continue de mol√©cules √† haute valeur ajout√©e.¬†Les r√©actions r√©alis√©es en flux permettent un meilleur contr√īle de param√®tres tels que le m√©lange, la temp√©rature et la pression.¬†¬†Elles permettent √©galement de manipuler des compos√©s tr√®s r√©actifs de mani√®re s√Ľre et efficace, en r√©duisant consid√©rablement les risques.¬†¬†De plus, les proc√©d√©s en flux continu peuvent offrir des avantages en termes d’intensification des processus, de suivi en ligne et de d√©veloppement de r√©actions t√©lescop√©es.

L’√©quipe LabFact poss√®de un nombre important de projets en cours dans ce domaine, avec une expertise dans le traitement des flux pour les transformations thermiques, photo- et √©lectrochimiques,‚Ķ; diff√©rents √©quipements sont disponibles, aussi bien commerciaux que sur mesure.¬†Nous disposons √©galement d’imprimantes 3D pour la conception/fabrication √† la demande de r√©acteurs microfluidiques
