Flow Chemistry Applications

The application of continuous flow micro reactors is based on solving problems that are currently observed in the batch technology being used for the synthesis of chemical products in the fine chemical and pharmaceutical industry. The following advantages can be expected when using a continuous flow micro reactor in place of a conventional batch reactor:

 

  • Safe use of more extreme reaction conditions (even for dangerous reactions);
  • Increased selectivity of reactions; a reduction in the use of raw materials and energy with reduced waste production;
  • Decrease in development time; a shorter experiment time, no need for scale-up;
  • Reduction in product lead time; combination of more synthetic steps in a single micro reactor.
