Contribution to the Qualification of Technical Microwave Systems and to the Validation of Microwave‐Assisted Reactions and Processes

New insights into the energy efficiency of reactions in a microwave field and the development of a concept to transfer thermally heated reactions to microwave-assisted reactions are reported utilizing commercial modular microwave systems. Particularly, questions on the qualification of technical microwave systems and their measurement and monitoring technology as well as on the validation of chemical reactions and processes are discussed. For that purpose, some technical microwave systems of different manufacturers were tested. The applicability for the implementation of chemical reactions and processes was determined. Conversions and yields of some reactions were compared by the dependence of irradiation modus, temperature and temperature measurement method.
