Summary
Thefields ofmicrowave chemistry andmaterial processing have grown immensely
since the 1990s, and considerations from a physicochemical point of view are
advancing the microwave effect. Studies of chemical processes using the features
of microwave heating have also become popular. Choosing the optimal frequency
of the microwaves for each situation can promote microwave chemistry further.
Moreover, the use of several microwave frequencies could also prove beneficial
to the chemical industry in microwave organic chemistry, as it may open up new
applications of microwave-assisted organic syntheses, such as solvent-free reactions
and supported reactions, as well as the preparation and reactions of inorganic
solids, particularly where solvents cannot be heated by the most commonly
used 2.45 GHz microwaves.
