A far-infrared heating reactor is a high-efficiency chemical reaction device. It works on the principle of far-infrared radiation heating, which intensifies the internal vibration of reactant molecules and thus increases the reaction rate and reaction efficiency.
Far-infrared rays are electromagnetic waves with wavelengths ranging from 3 to 1000 microns. They carry low energy yet can penetrate the surface of materials and act directly on the interior of molecules. When far-infrared rays irradiate reactants, the vibration frequency inside molecules rises and the intermolecular bond energy decreases, making chemical reactions easier to proceed. In addition, far-infrared rays can accelerate the diffusion rate of reactants and promote interactions between them, further boosting the reaction rate and efficiency.
The advantages of far-infrared heating reactors include fast heating speed, high reaction efficiency, low material consumption, short reaction time and uniform reaction temperature. Moreover, far-infrared heating can avoid problems such as local overheating and reactant decomposition that may occur in conventional heating methods, so as to improve reaction selectivity and yield.
Far-infrared heating reactors are widely used for chemical reactions in organic synthesis, biochemistry, materials science and other fields. For instance, they enable high-efficiency organic synthesis reactions such as esterification, alcoholysis and alkylation. They are also applicable to biochemical reactions including protein crystallization and DNA synthesis. In materials science, they are widely adopted for the preparation of nanomaterials and the synthesis of polymer materials.
