Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of chemical synthesis equipment, in particular to a continuous flow synthesis equipment. Background Art
[0002] Continuous flow synthesis is continuous flow chemistry, which means that chemical reactants continuously enter the reaction station of the synthesis equipment to react, and the products after the reaction are continuously output. The continuous flow synthesis equipment mainly includes three parts: the feeding part of the chemical reactants, the reaction part and the discharge part. The feeding part is used to input chemicals into the reaction part, the reaction part is used to provide a reaction place for the chemicals, and the discharge part is used to output the products after the reaction.
[0003] A Chinese patent application (or patent) with publication number CN115805049A discloses a continuous flow synthesis device, including: multiple reactors; a transmission pipeline network, including multiple interconnected connection nodes, and each connection node can be controlled to be interconnected or disconnected with an adjacent connection node; each reactor is connected to one or more of the connection nodes, so that any two reactors can be interconnected or disconnected. The above-mentioned continuous flow synthesis device connects all the reactors through the transmission pipeline network. When the process flow needs to be changed, there is no need to remove the pipeline, and only the corresponding connection node needs to be controlled so that the two connection nodes connected to the two reactors can be connected to each other, and the two reactors can be interconnected to transmit materials. If the two connection nodes connected to the two reactors are controlled to be disconnected from each other, the two reactors can be disconnected from each other, no interference will occur, and there is no need to disassemble and install the pipeline again, which greatly reduces the cost of changing the process flow of the continuous flow synthesis device.
[0004] The above-mentioned continuous flow synthesis equipment is provided with multiple low-temperature reactors, ultra-high temperature fixed bed reactors and PTEE high-temperature reactors, and they are all installed on the honeycomb unit, but they are arranged in a disorderly manner and are close to each other, so the above-mentioned three temperature reactors are prone to mutual temperature interference; and the low-temperature reactor, ultra-high temperature fixed bed reactor and PTEE high-temperature reactor do not have any temperature feedback structure when reacting compounds, so the temperature condition in the reactor cannot be checked. To this end, we provide a continuous flow synthesis equipment to solve the above-mentioned problems. Utility Model Content
