Precise gas dosing for flow chemistry applications
The Gas Module enables accurate dosing of gases for flow chemistry applications and integrates seamlessly with the H-Cube Pro and Phoenix Flow Reactor systems. By extending gas handling capabilities, the module allows a wider range of gas-phase reactions to be performed under controlled conditions.
The system supports reactions at pressures of up to 100 bar, making it suitable for applications such as oxidation, carbonylation, hydroformylation and hydrogenation.
How does the gas module work?Â
The Gas Module is designed to operate with an external gas source, typically a gas cylinder supplying gas at a pressure between 25 and 140 bar.
During operation:
- The desired gas is selected from the module’s predefined gas library or a new gas can be configured by entering its properties.
- A built-in mass flow controller accurately doses the selected gas into the liquid stream.
- The module works together with the H-Cube® Pro or Phoenix™ Flow Reactor to perform reactions at pressures of up to 100 bar.
This allows gas-phase reactions, including carbonylations and oxidations, to be carried out under elevated pressure, expanding the range of possible chemistries.
Compatible gases
The Gas Module supports 14 predefined gases:
- Compressed air
- Hydrogen (Hâ‚‚)
- Nitrogen (Nâ‚‚)
- Oxygen (Oâ‚‚)
- Carbon monoxide (CO)
- Carbon dioxide (COâ‚‚)*
- Methane (CHâ‚„)
- Ethane (C₂H₆)
- Ethylene (Câ‚‚Hâ‚„)
- Nitrous oxide (Nâ‚‚O)
- Nitric oxide (NO)
- Argon (Ar)
- Helium (He)
- Syngas for hydroformylation
Other gases with well-known thermodynamic properties and suitable compatibility can also be introduced.
*COâ‚‚ requires preheating.
