Description

Technical Field

[0001] The utility model relates to the technical field of reactor feed control, in particular to a chemical reaction control device. Background Art

[0002] At present, in the production process of fine chemicals, especially in the production process of pharmaceutical intermediates, it is often involved to add solid powder materials into the reaction system of the reactor. In the process of feeding, the powder materials fly everywhere, the operating environment is poor, the work intensity of the operators is high, and the harm caused by the adhesion of the powder to the human body is also great. After the feeding is completed, the workload of on-site cleaning is large.

[0003] For example, in the synthesis process of 7-ACCA (an important intermediate for synthesizing the second-generation cephalosporin, such as cefaclor), dilute hydrochloric acid and sodium dithionite need to be added simultaneously during the reaction, and the temperature and pH value of the reaction system are controlled by controlling the addition rate of the two materials. During the addition of sodium dithionite, sodium dithionite is easily oxidized by absorbing oxygen when exposed to the air, and is also easily heated and deteriorated by absorbing moisture. It can also seize oxygen in the air to form agglomerates and emit a pungent sour smell, and react violently and burn when it comes into contact with water. When synthesizing 7-ACCA, the solvent used in the reaction system is distilled water. Water vapor will rise along the feed port and contact with sodium dithionite, which will cause the sodium dithionite to decompose and form agglomerates that block the pipeline. In severe cases, it will cause fire, which is very dangerous. Therefore, it is necessary to develop a chemical reaction control device. Utility Model Content
