Study On Specific Effect In The Interaction Between Microwave And Chemical Reaction

Microwave has been found to be an efficient heating method in chemical industry. But so far, the interaction between microwave and chemical reactions has not been deeply understood. It restricts the wide application of microwave in chemical industry. Meanwhile, the specific effects become the focal point of scientist. Chemical reactions are non-equilibrium systems which could not be simplely considered as mixture of substances in microwave chemistry. In this paper, we study on the key problems of specific effects in the interaction between microwave and chemical reaction from the experiment and theory aspects. The results from this study are useful to understand the mechanism of the interaction between microwave and chemical reaction and extend application of microwave chemistry industry. Meanwhile, it is helpful for explaining the specific effect in microwave chemistry.The main contents and innovation points of this paper are as follows:(1) The complex permittivities of these organic reagents were measured in 2.45GHz by resonance perturbation method. The analysis and the measurement are helpful for the microwave-induced organic synthesis.(2) We firstly introduce the complex impact factors of different ion based on the experimental data and proposed a new model to calculate the complex effective permittivity of aqueous electrolyte solutions at microwave frequency. This method overcomes the disadvantages, such as complications and limitations using the fitting...
