How flow chemistry can make processes greener
Case study 1 Methylation with DMC.
Increasing reaction efficiency through access to a wider range of reaction conditions
Efficient utilization of energy and time is fundamental to green chemistry and engineering. These factors are directly related to the rate of a chemical reaction, as a fast reaction will require less operating time. Economical use of space is also important, and fast reactions may allow for a smaller reactor to be utilized, particularly in continuous processes. The most straightforward way to increase reaction rate is with an increase in temperature; however, in a batch reactor, this is generally limited to the atmospheric boiling point of the solvent or reagents. In a flow reactor, pressure and temperature can be safely manipulated far beyond atmospheric conditions. Analogous to microwaves synthesis,1 reactions done in flow are often faster than in the corresponding batch reactions, which gives…
