Microwave heating for chemical reactions or extractive processes is faster, cleaner, greener and safer than traditional heating methods. C-Tech Innovation offers a continuous flow microwave chemical reactor that allows easy scale-up of chemical reactions from laboratory to production scale. The system gives several benefits over traditional batch chemical reactors:

  • Better yields and fewer by-products
  • Faster, more throughput
  • Reduced energy use of up to 90% vs. conventionally heated batch reactions
  • Cleaner: no hot oil, no fouling of hot surfaces
  • Greener: higher yields, less by-products, less catalyst, less waste
  • Safer: lower inventories, easy temperature control

The benefits of using microwave reactors instead of conventional heating mantles and heated vessels are a result of the following features of continuous microwave heating technology

  • Microwave heating is volumetric: it heats the reaction mixture directly, not through heated surfaces and conduction or convection.
  • Heating is applied evenly throughout the reaction mixture, with no hot-spots or cold-spots.
  • Microwave heating is instantly controllable. There is no thermal inertia. The energy input responds immediately to the control input.
  • Microwave heating is easily scalable. The heating takes place in a quartz tube, and the flow and hydrodynamic conditions are well characterised which allows for confidence in scale up.

What we can do for you

C-Tech Innovation supplies continuous flow microwave reactors to client specification, based on our QULOM MCP-6000 unit (Continuous Microwave Pressurised), rated at up to 250 °C and 25 bar pressure. Throughput is dependent on unit specification and target temperature. The units can handle a wide range of solvents – any material that contains an electric dipole is suitable for microwave heating, including water, ethanol, methanol, DMSO, TMF, DMF and others. Non-polar solvents may also be heated using microwaves if 10% or so of a polar solvent can be included.

Our team are experts at developing microwave chemistry and our units have been used to develop microwave assisted organic synthesis (MAOS) technology for pharmaceutical synthesis, fine chemical synthesis and extractive solvent processes. We can supply complete process systems, reactors for integration into existing systems and mobile skid mounted units. We can carry out laboratory development work to define process conditions. We would be pleased to talk to you about a bespoke solution for your process challenge.
