Description

technical field [0001] The invention relates to the field of chemical synthesis equipment, in particular to a multifunctional continuous flow synthesis device. Background technique [0002] Flow synthesis, also known as continuous flow chemistry, has excellent control functions on reaction conditions, such as time, temperature, reagents, mixing and other conditions. It innovatively integrates traditional independent and separate synthesis operations to speed up The speed of synthesis, especially the ability to carry out dangerous and difficult reactions. The reaction selectivity of flow synthesis is very high, which is of great significance to the fields of green chemistry and laboratory automation. [0003] Existing flow synthesizers are usually integrated non-detachable devices with relatively single functions, and usually can only perform continuous heating reactions, which cannot meet the needs of complex experiments. Therefore, it is of great application value to impr...
