Microwave Chemistry




  • The heat is formed directly and rapidly in the sample.

  • Energy is not wasted in heating furnaces or oil baths.

  • The entire volume of the reactor can be heated (virtually) uniformly.

  • Selected volumes of the sample (including microscopic regions) can be selectively heated.


Conventional heating usually involves the use of a furnace or oil bath, that heats the walls of the reactor by convection or conduction. The core of the sample takes much longer to achieve the target temperature (Particularly when heating a large sample of ceramic bricks, for example. Rapid and Homogeneous heating has the following benefits:


Some of these effects are derived from Superheating or hot spots, well known effects in Microwaving .

Selective heating is particularly important in the microwave heating of supported metal system comprising a Polar solvent and an apolar solvent obtain different temperatures. Applied in a Phase Transfer Reaction a water phase reaches a temperature of 100°C while a Chloroform phase would retain a temperature of 50°C. Microwave chemistry is particularly effective in Dry Media Reaction s.
