In industry, it serves as an important organic synthesis intermediate, used in the production of dyes, pharmaceuticals, ion exchange resins, and other products. In laboratories, it is a commonly used chemical reagent, playing a key role in organic chemistry research and experimental procedures.
[0003] In traditional reactors, reactants are mainly mixed directly in an agitator, and the contact area is limited, which leads to a restricted reaction rate.

It is difficult to increase the product concentration, unreacted raw materials are easily left, and the quality consistency of different batches of products is poor, which makes it difficult to meet the needs of high-end applications. In addition, the reactor is large in size and can accommodate many reactants. Once an accident occurs, the harm is serious and the emergency treatment is also relatively complicated. Therefore, a device for producing high-concentration trimethylamine hydrochloride is needed to solve the above problems. Utility Model Content

[0008] As a preferred embodiment, a circulation pump is provided on the circulation pipe, and one end of the circulation pipe is connected to the reactor.

By setting the microreactor 5, the microreactor 5 can first extract a part of the materials from the hydrochloric acid storage tank 4 and the trimethylamine storage tank 3 respectively through the pipeline, and then these materials can undergo micro-reaction in the microreactor 5.
