Description

Technical field:

[0001] The utility model relates to the technical field of dichloropyrimidine production, in particular to a chlorination reaction device with dispersed feed for the production of 4,6-dichloropyrimidine. Background technology:

[0002] The broad understanding of the dispersed feed chlorination reaction equipment for the production of 4,6-dichloropyrimidine is a container with physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. Reactors are widely used in petroleum, chemical, rubber, pesticide, dye, medicine, and food. They are pressure vessels used to complete processes such as sulfidation, nitration, hydrogenation, hydrocarbonization, polymerization, and condensation. 4,6-dichloropyrimidine is used as a pharmaceutical intermediate for the production of sulfonamide-6-methoxypyrimidine. 4,6-dichloropyrimidine is made by reaction in a reactor.

[0003] For example, a reactor for dichloropyrimidine production with authorization announcement number "CN213314969U" connects the conduit with the pressure relief pipe, so that the gas inside the reactor body enters the pressure relief box from the conduit, relieves the pressure on the reactor body, prevents the reactor body from being damaged due to excessive pressure, and enables the staff to close the reactor body in time for processing. When the pressure inside the reactor body returns to normal after the pressure is relieved, the elastic force of the spring pushes the slide to reset, so that the sealing block resets and blocks the conduit, so that the gas is stored inside the pressure relief box, and prevents gas leakage from causing environmental pollution. However, when the reactor for dichloropyrimidine production is used for stirring and chlorinating dichloropyrimidine, the stirring position of the equipment is fixed, and the wave generated by the stirring at the fixed position is small. It also needs to be used for a long time to fully stir and chlorinate, which reduces work efficiency. At the same time, after the reactor for dichloropyrimidine production is used for stirring and chlorinating, a small amount of impurities will remain in the equipment, and it needs to be manually cleaned before the subsequent stirring and chlorination reaction, which increases manual labor.
