Recently, the use of microreactors for organic reactions has drawn a lot of attention. [ 1-3 View all references ] The typical dimensions of microreactors are in the range of 10–500 µm. Because of this microstructure and high surface-area–to–volume ratio, it has particularly excellent heat and mass transfer characteristics. [ 4 4. (a) Iwasaki , T. ; Yoshida , J.
