Microwave reactors are equipped with pressure sealing technology, which means heating conditions above reflux are often used in microwaves. The speed at which it can reduce reaction times can be found by applying the Arrhenius law/equation: For every increase of 10 C, the reaction time is cut in half. For example, a reaction that may take a ...
Microwave Synthesis. It has long been known that molecules undergo excitation with electromagnetic radiation. This effect is utilized in household microwave ovens to heat up food.
