Microwave chemistry

The microwave chemistry is concerned with the use of microwaves in the chemical industry and in the laboratory for synthesis or analysis.

The major advantage of microwaves for heating is that the chemicals can be heated directly, and at all points at the same time and not on vessel walls, and with the disadvantage of uneven heating convection with the formation of cold and hot spots. This optimum energy input and energy intake leads to lower response times and reduced energy consumption. In addition, higher yields possible with fewer side products, as well as a high degree of purity of the reaction products. Since you can control the power supply very quickly and also stop them, there are also safety benefits.

The systems designed for the heating of water household microwave ovens are available only for aqueous solutions or reactions with water. For the heating of other substances needed devices having other wavelengths, they are not equal demanding and require correspondingly high costs.
