Microfluidics for Chemistry Applications

because of the miniature channel dimensions micro reactors demonstrate a high volume to surface ratio. As a result micro reactors reveal the following advantages compared to batch processes:

  • Perfect mixing within seconds caused by the fast diffusion processes
  • High efficient heat exchange and temperature control even for strongly exothermic reactions
  • Insignificant reaction volume, which allows the safer handling of dangerous reactants, such as explosives or toxic material

This enables users to complete chemical reactions in a continuous process mode under controlled reaction conditions (mixing quality and temperature distribution/control). Furthermore, the excellent control of reaction parameters enables the users to avoid unwanted side products and therefore improves the product quality already in the reaction step.

1. Photochemistry

  • Introduction: the idea of photochemistry is to trigger chemical reactions by the irradiation of the reagents with light. The atoms or molecules absorb the light of the specific wavelength and a chemical reaction starts. Glass represents a perfect reactor material for this application.
  • Detailed description: as a result of the thin liquid film used in such micro reactor the yield of light is much higher than in a larger batch reactor. It is also possible to fabricate flow cells with a quartz glass window to open a wide range of wavelengths for special applications.
  • Applications: synthesis of chemical intermediates and products which require a high purity, e.g. photocyclization, photocycloaddition, photoisomerization reactions.
  • Markets: general chemical and pharmaceutical industry, especially fine chemistry and medicinal chemistry for low volume but high quality production

2. Separation Technology

  • Introduction: after a chemical reaction is completed it is necessary to separate the product from the side products or solvents for work up or to perform another reaction step. Separation modules, which work continuously provide a way to avoid batch processing. For this purpose we have developed different modules for liquid/liquid and gas/liquid separation.
  • Detailed description: Invenios has developed modules for separation with different functionality. ForĀ  two-phase systems separation, a mixer/settler setup or membrane technology could be used. We apply a surface modification within a closed channel system to make this target area hydrophobic. For the gas/liquid separation, either capillary forces or membranes can be used.
  • Applications: synthesis of chemical intermediates and products which require a high purity, e.g. separation of ionic liquids, Ozonolysis, synthesis of organic polymers.
  • Markets: general chemical and pharmaceutical industry, especially fine chemistry and medicinal chemistry for low volume but high quality production

3. Nitrations

  • Introduction: nitration reactions require the use of reactor materials which are stable against highly corrosive media and, in addition, enable the fast cooling of reaction heat and a precise temperature control. Invenios reactors can satisfy all these requirements.
  • Detailed description: the glass material allow the users to work with even high concentrated sulfuric acid at elevated temperatures. Furthermore the high volume to surface ratio provides the basis for a fast heat exchange from the reaction mixture to the coolant.
  • Applications: synthesis of chemical intermediates and products which require a high purity, e.g. direct nitration of organic compounds.
  • Markets: general chemical and pharmaceutical industry, especially fine chemistry and medicinal chemistry for low volume, but high quality production
