Abstract

The practical applicability of microreaction technology is an unsolved problem. A program has been developed for potential users of microreaction technology to predict the feasibility of applying this technology for a specific synthesis in a microreactor. The program consists of two parts. In the first part basic process equations and parameters and a simplified model of the microreactor are used to obtain preliminary information on the applicability of the microreactor. The second part provides a more detailed consideration of the potential of applying a microreactor, using a detailed microreactor model (CPU intensive). This study presents the program structure and features, and also test cases on technically relevant reactions.
