Flow chemistry systems are particularly suitable for hazardous gas handling for the following reasons:
- Pressure can be safely applied in the flow system. The addition of pressure means that a far greater proportion of the gas will be in solution during the reaction than is the case in traditional batch reactors.
- Comparatively small amounts of gas are continually exhausted by the system, eliminating the need for many of the special precautions normally required for handling toxic and/or flammable gases
- Systems allow the use of a fixed bed catalyst. Combined with low solution concentrations, this allows all the starting material to be adsorbed to catalyst in the presence of gas
- The greatly enhanced mixing of the solid, liquid and gaseous phases allows the researcher to exploit the kinetic benefits of elevated temperatures without being concerned about the gas being displaced from solution
- They open the opportunity for a hazardous gas to be synthesized and immediately consumed in a continuous process eliminating the need for isolation and storage of the hazardous gas as is required when traditional batch reactors are used.
