What Is Flow Chemistry?

Instead of batch production, flow chemistry is a type of chemical reaction that is basically running in continuous flow stream. For you to understand things a lot easier, the pumps move the fluid in the tube and by the time that the tubes are connected, the fluid forms into one. In case that the fluids are reactive, there will be a spike in reaction.

Flow chemistry is well established and known technique for use at big scale when trying to manufacture huge quantities of given material. However, it was just recently when the term is coined after the application on laboratory scale. More often than not, micro-reactors are put into used.

Continuous reactors are manufactured using non reactive material similar to glass, polymers and stainless steel and typically tube-like. When it comes to the method of mixing, it can be either of the two, static mixers or diffusion. The continuous flow reactors create good control on the reaction condition which include time, mixing and heat transfer.

The residence time for reagents in reactor or the amount of time to which the reaction is being cooled or heated is being calculated from volume of reactor as well as flow rate through it. For this, the reagents are pumped slowly and/or it is using bigger volume reactor to be able to attain longer residence time.

When it comes to production rates, this can be liters per minute to nano-liters per minute.

Few examples of the flow reactors are spinning tube reactors, spinning disk reactors or otherwise called as Colin Ramshaw, oscillatory flow reactors, multi cell flow reactors, microreactors, aspirator reactors and hex reactors. In regards to aspirator reactor, a pump is used to propel one reagent that sucks in the reactant.

Smaller scale of micro-flow reactor or the micro reactors may just be perfect on process development experiments. Although, it is possible to operate flow chemistry at bigger scale, synthetic efficiency benefits from mass transfer as well as improved thermal and also, mass transport.

Processes development is changing from serial approach to parallel. When it comes to batch, the chemist will first work on it which will then be followed by a chemical engineer. Now for flow chemistry, this changes to parallel approach to which both the chemical engineer and the chemist are working side by side. Typically, there’s plant setup in lab wherein there’s a tool intended for both. This particular set up may be used either for non commercial or commercial setting.

It is possible to run experiments in flow chemistry by using complex techniques such as solid phase chemistries while solid phase reagents, scavengers or catalysts could be used in solution and then, pump it through glass columns.
