Study on the key problems of interaction between microwave and chemical reaction

“…In recent years, many experiments have proved that microwave can greatly enhance the reaction rate of some chemical reactions, which are hard to react under conventional conditions [3,4]. For example, some organic and inorganic reactions in 560 W microwave oven can react faster to certain extent than those under conventional heating conditions [5,6], and the use of microwave can save energy as well [7].…”

“…4) Effects obtained from microwave effect satisfy the characteristics of the non-thermal effect: window property, coherency, coordination and nonlinearity. Senise and Jermolovicious from IMT found that there were power windows when synthesizing emulsified unsaturated polymer resins [4]. Many other literatures reported the non-thermal effect in the related experiments [45−49].…”
