Description

technical field [0001] The photochemical reaction of this equipment is closely related to our daily life. It is closely related to organic synthesis, life chemistry, material chemistry, environmental chemistry, dye chemistry and many other aspects. Therefore, this equipment has a wide range of applications. Background technique [0002] Photochemical reaction refers to the chemical reaction that a substance generally produces under the irradiation of visible light or ultraviolet light, and is a reaction triggered by the absorption of photons by the molecules of the substance. The process has good selectivity and can be carried out at normal temperature and pressure, so photochemical reactions are widely used in life. However, photochemical reactions still have the following disadvantages: [0003] 1) The light source is placed inside the reaction, which is not only not conducive to the expansion of the reactor, but also has a potential risk of fire. The temperature of the ...

AI Technical Summary

Problems solved by technology

[0003] 1) The light source is placed inside the reaction, which is not conducive to the expansion of the reactor, but also has the potential risk of fire

The temperature of the light source is high, the working environment is harsh, and the life is short;

[0004] 2) The gas absorption and photochemical reaction are in the same equipment, the existence of a large number of bubbles makes the light energy dissipate rapidly, the catalytic efficiency is not high, and the economic cost is increased;

[0005] 3) Since the main component of the reactor is glass and has a complex structure, the operating conditions can only be carried out under normal pressure, so that the oxygen concentration in the reaction liquid is low, and the solvent loss with the exhaust gas is large
