Organic Synthesis in Microreactor Systems
Enhanced heat and mass transfer, reduced reaction volume, and the ability to run several experiments in parallel render microreactors powerful instruments for scanning and optimizing chemical reaction conditions. Furthermore, the high mechanical strength and thermal conductivity of silicon microreactors permit the exploration of organic syntheses at higher temperatures and pressures than can be...
متن کاملSingle-step radiofluorination of peptides using continuous flow microreactor.
18F radiolabelling of peptides bearing two different prosthetic groups was successfully conducted in a continuous flow microfluidic device for the first time. Radiochemical yields were dependent on precursor concentration, reaction temperature and flow rate. The choice of leaving group had a dramatic influence on the reaction outcome. Rapid reaction optimization was possible.
متن کاملFlow microreactor synthesis in organo-fluorine chemistry
Organo-fluorine compounds are the substances of considerable interest in various industrial fields due to their unique physical and chemical properties. Despite increased demand in wide fields of science, synthesis of fluoro-organic compounds is still often faced with problems such as the difficulties in handling of fluorinating reagents and in controlling of chemical reactions. Recently, flow ...
متن کاملMicroreactor Fabrication by Photolithography and Analysis for Synthesis of Biodiesel
This work presents an analysis about microreactors of different geometries for the biodiesel synthesis. The microreactors were made by a polymeric substrate with the photolithography technique. Simulations were made using the computational fluid dynamics software ANSYS-CFX. They show the flow behavior through the microchannels. Experiments were performed to produce biodiesel, with syringe pumps...
متن کاملCatalytic Synthesis of Hydrogen Peroxide in a Capillary Microreactor
The direct synthesis of hydrogen peroxide from hydrogen and oxygen has been investigated in a capillary and a stacked microreactor, where Pd/C catalyst was coated on the silicone wall of a microchannel. In order to make the system of H2O2 production compact, a flow-through solid polymer electrolyte (SPE) electrolyzer, which was used for the evolution of H2 and O2 instead of gas cylinders, was c...
