| Outline of Final Research Achievements |
As a microwave can heat an object directly and internally, it can induce a selective heating, a heat spot and a superheat. Microwave heating method has been used in various chemical processes. It has been reported that the microwave heating provided the improvement of reaction rate and yield, the appearance of new reaction path, the improvement of selectivity, and so on. However, its precise mechanism has not been sufficiently clarified.
In this study, a new continuous reaction field was constructed by applying the microwave heating for fluidized bed, dry type, wet type pulverization, micro flow channel transportation, respectively. In the newly developed MW-TG device, we clarified the mechanism of thermal and nonthermal effect by microwave heating, and reduced the cost for synthesis of functional nanoparticles, particle complexation and rare metal recovery from waste.
