Description

Technical Field

[0001] The present application relates to the field of photoreaction equipment technology, and in particular to a photoreactor and a method for using the same. Background Art

[0002] Photocatalysis refers to the use of solar energy or other light energy to achieve the organic transformation of different chemical substances. Compared with traditional heating, photocatalysis is more environmentally friendly and has less pollution to the environment. Therefore, the field of photochemistry has attracted more and more attention from scientists.

[0003] At present, a special photoreaction device is required to realize a photochemical reaction. The existing photoreaction device usually includes a reaction bottle containing a reaction liquid and a light source. The light source is arranged around the reaction bottle to irradiate the reaction liquid. When working, the light source irradiates the reaction liquid in the reaction bottle from the outside to the inside to provide light for the photocatalytic reaction.

[0004] With the continuous development of photocatalytic technology, scientists are not only limited to room temperature photoreactions, but temperature also has an important influence on photocatalytic reactions. For example, for chiral controlled reactions, room temperature may cause them to racemize, and they need to be carried out under low temperature conditions; for reactions with high bond energy, heating is required to assist photocatalysis. During the experiment, for photocatalytic reactions that require low or high temperatures, the reaction bottle needs to be placed in an oil bath or cold hydrazine; however, the existing photoreaction device achieves photocatalytic reactions by surrounding the light source on the side of the reaction bottle and irradiating the reaction liquid in the reaction bottle from the outside to the inside. If the reaction bottle is placed in an oil bath or cold hydrazine, the light source cannot provide illumination for the reaction liquid, so that the existing photoreaction device can only perform photocatalytic reactions at room temperature, which cannot meet the needs of high or low temperature photocatalytic reactions.
