Mar 01, 2017 The results of these chemical synthesis carried out in such reactors have to be considered as demonstrative examples only; because of the non-control of the main parameters governing the microwave heating and the flow, the results are almost depending of the system used and the reproducibility becomes difficult and quite impossible.

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 ...

Microwaves are electromagnetic waves with extremely short wavelengths. They are electromagnetic waves like radio waves, infrared rays, and visible light. The frequency range of microwave is 300MHz-300KMHz, that is, the wavelength is 1mm-1m. The principle of microwave heating: microwave heating is the use of microwaves as an energy source.

multiwave microwave reactors for synthetic chemistry applications. What makes this technology so interesting to chemists? While the microwave range is large (1-100 GHz, 300-3 mm), a frequency of 2.450 GHz is preferentially used for conventional microwaves because it provides the right penetration depth
