Sažetak
Microreaction technology is gaining important place in different fields of application from scientific researches to industrial production. They are defined as miniaturized reaction systems fabricated by using, at least partially, methods of microtechnology and precision engineering. Reducing dimensions of the reaction system (typical dimensions of microchannel are in the range of 10 to 500 µm) they exploit rapid reaction rates and minimize heath and mass transport limitations that usually present a problem in conventional reactor systems. Microreactors exhibit numerous practical and performance advantages when compared to traditional, equivalent macroreactors. The small dimensions of microchannel (submicrometers and submillimeters size) allow usage of minimal amounts of reagent under precisely controlled conditions and make it possible to rapidly screen reaction conditions and improve the overall safety of the process. Beside that, excellent mass and heath transfer, shorter residence time, smaller amount of reagents, catalyst and waste products comparing to macroscale reactors, lightweight and compact system design, simple scale-up procedure, laminar flow, effective mixing, short molecular diffusion distance and better process control, and small energy consumption are just some of the microreactors advantages. Furthermore, they could be easily coupled with numerous detection techniques together with the pretreatment of the samples on the one single chip. Having in mind all those benefits one of the main motivations for the use of microreactor technology is the gain in the yield and safety. In this work microreactor advantages will be demonstrated on couple of examples ranging from biotransformation and bioseparation processes to kinetic measurements and estimations of mass transfer parameters. For each process shown comparison with the macrosystem will be critically evaluated and discussed. Selected examples will be the clear demonstration of microreactors as powerful toll for sustainable process development.
