Microreactors have an extremely large volume-to-surface ratio and the mass
transfer path is minimal. That is why they provide information that would n
ot be available otherwise. This kind of information can be crucial for the
choice and the dimensions of a technical reactor. By two examples it is dem
onstrated that process development periods can be reduced essentially and t
hat potentials for process improvement can be found. (C) 2001 Elsevier Scie
