Continuous flow photochemical reaction module

Abstract

The invention relates to a continuous flow photochemical reaction module which comprises three or four layers of wall bodies overlapped alternately up and down. In the four-layer wall body structure,wall bodies at the topmost layer and the lowermost layer are light-permeable glass plates, and wall bodies of two layers at the middle are heat conductive plates made of heat conductive materials. Cavities formed between the glass plates and the heat conductive plates are reaction liquid cavities, and a cavity formed between the two heat conductive plates is a heat transfer medium cavity. Incidentlight emitted by light sources arranged at the upper part and the lower part of the reaction module almost only needs to penetrate a layer of glass plate and can reach the reaction liquid cavities directly, so as to help to improve the utilization of light efficiency and improve the reaction efficiency. The inner sides of the reaction liquid cavities are the heat transfer medium cavity, the reaction liquid cavities and the heat transfer medium cavity are separated only by the heat conduction plates, heat generated by the reaction can be quickly transferred out and the heat conduction performance is improved. In the three-layer wall body structure, the upper layer is a glass plate, and at least one layer at the middle is a heat conductive plate. A reaction liquid cavity and a heat exchangecavity are formed from upper and lower at intervals.

Description

technical field [0001] The invention relates to the field of optical flow reactors for photochemical reactions, in particular to photochemical reaction modules with continuous flow channels. Background technique [0002] A photochemical reaction refers to a chemical reaction initiated by an atom, molecule, free radical or ion absorbing a photon, and is an important type of reaction in the chemical synthesis process. This type of chemical reaction has a number of advantages which, depending on the specific reaction in question, manifest themselves alone or in various combinations as follows: (1) Light can be considered highly specific and ecologically clean" reagents”; (2) photochemical methods can provide a less “invasive” route in chemical synthesis than thermal methods; (3) photochemical reactions can contribute to the safety of industrial processes because they are generally at or below room temperature (4) organic compounds undergoing photochemical reactions do not requ...
