Fluorination reactions in microreactors

Chemical Communications, 2008
The DAST-mediated conversion of a range of alcohols to the corresponding fluorides in a microstructured device is described. This safe, practical fluorination method will facilitate reactions currently challenging on large scale.

An optically accessible pyrolysis microreactor

Review of Scientific Instruments, 2016
We report an optically accessible pyrolysis micro-reactor suitable for in situ laser spectroscopic measurements. A radiative heating design allows for completely unobstructed views of the micro-reactor along two axes. The maximum temperature demonstrated here is only 1300 K (as opposed to 1700 K for the usual SiC micro-reactor) because of the melting ...

Chemical Synthesis in Microreactors

2009
To develop a new generation of drugs, pharmaceutical companies need to be able to synthesise and screen novel chemicals with enhanced speed. New technology that would enable a cost neutral step change in the number of potential drug candidates would provide a distinct competitive advantage.

Microreactors with Electrical Fields

2010
The use of electric fields in chemistry is considered an important concept of process intensification. The combination of electricity with chemistry becomes particularly valuable at smaller scales, as they are exploited in microreaction technology. Microreactor systems with integrated electrodes provide excellent platforms to investigate and exploit ...

Photocatalysis in microreactors

Journal of Photochemistry and Photobiology A: Chemistry, 2004
Abstract A photocatalytic microreactor with immobilized titanium dioxide as photocatalyst and illuminated by UV-A light emitting diodes was constructed and tested for the degradation of the model substance 4-chlorophenol. The microreactor consisted of 19 channels with a cross-section of approximately 200 μm ×300  μm.
