Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat exchanger cooling, in particular to a perfluorobutylsulfonyl fluoride reaction heat exchange efficient cooling equipment. BACKGROUND

[0002] Perfluorobutylsulfonyl fluoride (C4F9SO2F) is an important perfluoroalkyl sulfonyl fluoride compound. Due to its strong electron-withdrawing perfluorobutyl (-C4F9) group, its sulfonyl fluoride group (-SO2F) has high reactivity, mainly as a sulfonylating agent to participate in various nucleophilic substitution reactions. The production and application environment of perfluorobutylsulfonyl fluoride indeed has very high requirements for equipment, so in the reaction of perfluorobutylsulfonyl fluoride, the selection of heat exchange device needs to combine its reaction characteristics (such as corrosion, temperature range, material state, etc.), to ensure efficient temperature control. In the reaction of perfluorobutylsulfonyl fluoride, heat exchange is generally carried out through a jacketed heat exchanger. The outer layer of the reaction kettle is designed with a jacket, and the heat exchange medium (such as perfluoropolyether oil, silicone oil or condensed gas) circulates in the jacket, and indirect heat exchange is carried out between the kettle wall and the internal material. The structure is simple, there is no internal heat exchange component, direct contact between the medium and the material is avoided, and the pollution risk is reduced, which is especially suitable for batch reactions of liquid or slurry materials.

[0003] However, in the use process of the existing heat exchanger, it is not convenient to accurately cool the inner layer of the reaction kettle with condensed gas. Generally, the whole is cooled, and when the internal reaction solution quality is different, the temperature produced is also different, which may cause overcooling or poor cooling effect, and the temperature in the pipe cannot be accurately controlled. At the same time, in the existing heat exchanger, when cooling the reaction kettle, there may be a lack of cooling area, resulting in low local temperature and high local temperature, causing uneven heating of the surface of the reaction device, affecting the subsequent reaction of the device, and also damaging the reaction device itself.
