Drug intermediate reaction tube and production line

Abstract

The invention provides a drug intermediate reaction tube and a production line, which belong to the field of pharmaceutical equipment. The drug intermediate reaction tube includes a main body, and the two ends of the main body are respectively an inlet section and an outlet section. The heat transfer rate of the inlet section is greater than that of the outlet section. The drug intermediate production line includes the above-mentioned drug intermediate reaction tube. Tube. The drug intermediate reaction tube and production line of the present invention, when in use, place the drug intermediate reaction tube of the present invention in a heat exchange environment, then mix the reaction raw materials and pass them into the main body from the inlet section, and the inlet section of the main body The heat can be quickly dissipated into the heat exchange chamber, so that the raw materials will not vaporize, and the reaction will continue; The temperature of the reaction is reduced too much, the reaction rate is kept at a high level, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical equipment, and more specifically relates to a drug intermediate reaction tube and a production line. Background technique [0002] In the production of a drug, an intermediate is produced by an exothermic reaction of three raw materials. This reaction is extremely sensitive to temperature. If the reaction temperature is too low, the reaction rate will decrease and the production efficiency will decrease; if the reaction temperature If the temperature is too high, the reaction raw materials will vaporize, leading to the termination of the reaction and even danger. Conventional reactors are generally used to carry out this reaction. In order to avoid vaporization of raw materials and ensure the continuous progress of the reaction, it is usually necessary to keep the reactor at a lower temperature, but this also leads to a lower reaction rate and a decrease in production efficiency.
