Parallel high pressure reactor is referred to as high pressure vindication. It is a new type of reaction synthesis scientific research instrument that combines the basic principles of synthetic chemistry and the concept of combinatorial chemistry. The so-called high-pressure parallel synthesizers, parallel reactors, parallel synthesizers, organic synthesis devices, parallel catalytic screening and evaluation and other reaction devices are all other names of such instruments. It is one of the necessary equipment for the exploration of reaction routes, optimization of conditions and efficient synthesis in the research and development of modern synthetic chemistry. Parallel reaction is suitable for modern reaction synthesis equipment with strict requirements on anhydrous, oxygen-free and air tightness of the system, wide temperature control range, accurate temperature control accuracy, strict reaction safety requirements, high scientific research efficiency requirements, and good repeatability requirements.
