The concept of “flow chemistry” defines a very general range of chemical processes that occur in a continuous flowing stream, conventionally taking place in a reactor zone.

The application of flow chemistry relies on the concept of pumping reagents using many reactors types to perform specific reactions.

The most common types of reactors are plug flow reactors and column reactors, whilst for specific chemistries more sophisticated reactor designs might be needed (e.g., photoreactors, electrochemical reactors, etc).

Set-Up:

Figure 1 shows an example of a schemtic of a flow system.

Exemple de schéma d'un système de chimie en continu

Figure 1

A flow system includes:

a) At least one pump with good chemical compatibility,
b) Manual or automatic valves,
c) A flow path,
d) A T,
e) A coil reactor or a glass mixer block/chip reactors for homogeneous syntheses,
f) A column reactors for heterogeneous syntheses,
g) A module for heating or heating/cooling,
h) Back pressure regulators.

 

Advantages of flow chemistry:

There are well-defined key advantages using flow technologies as compared to standard batch and microwave chemistry methods.

Flow chemistry, improves heat transfer & mass transfer/mixing for faster reactions, by superheating at elevated pressure.

Flow chemistry allows:

– To have high reproducibility and scalability, for instance, continuous processing can deliver 100s g to 10 Kg per day.

Certaines synthèses en continu, peuvent fournir entre 100g à 10kg de produit par jour

– To have extreme reaction conditions (high/low temperature, high pressure).

Useful solvents for flow with bp exceeding 150°C

– To do multistep (telescoping),
– To have in-line downstream processing,
– To make it possible to automate,
– To improve safety and mange hazardous reagents and intermediates, small reactor volumes minimize risk associated with hazardous intermediates.
