For every increase of 10 C, the reaction time is cut in half. For example, a reaction that may take a full day at room temperature would take approximately 2 minutes at 120 C. Many microwave reactors, including CEM’s Discover line, have the capability to heat to 300 C and have a maximum pressure threshold of 435 psi.
However, most chemical reactors using microwaves that have already been developed are batch-types, and there are few flow-types. Accordingly, the objective of this study is to develop a flow-type microwave-assisted chemical reactor, and moreover, we try to apply the reactor to microreaction technology.

Microwave chemistry is based on the efficient heating of materials by “microwave dielectric heating” effects. This phenomenon is dependent on the ability of a specific material (solvent or reagent) to absorb microwave energy and convert it into heat.
Microwave energy is a form of electromagnetic energy. Its frequency can impact the realm of molecular rotations. The electric field of a microwave heats matter through a phenomenon known as dielectric heating. As the electric field passes through a sample, energy is transferred to molecules through the mechanisms of dipole rotation and ionic ...
