Area of Science:

  • Chemical Engineering
  • Materials Science

Background:

  • Microreactors offer advantages in chemical synthesis due to high surface-area-to-volume ratios.
  • Scaling up microreactor production (numbering-up) is crucial for industrial applications.

Purpose of the Study:

  • To design and fabricate a novel 'pile-up' microreactor integrating ten microchannel layers.
  • To evaluate the performance of this microreactor for amide formation reactions.
  • To demonstrate the potential of numbering-up technology for fine chemical production.

Main Methods:

  • Fabrication of a ten-layered 'pile-up' microreactor using conventional photolithography, wet etching, and thermal bonding.
  • Integration of microchannel circuits into a single glass entity.
  • Performing an amide formation reaction between an amine and an acid chloride in the microreactor.

Main Results:

  • The 'pile-up' microreactor achieved a ten-fold increase in throughput compared to a single-layer device.
  • High amide formation reaction yields were maintained despite increased throughput.
  • The microreactor demonstrated a productivity on the gram-per-hour scale.

Conclusions:

  • The 'pile-up' microreactor design enables efficient scaling of microchemical processes.
  • This technology offers a viable alternative to conventional plants for fine chemical production.
  • Numbering-up of microreactors is a promising strategy for industrial chemical synthesis.
