Problems solved by technology

[0004] In order to solve the above technical problems, the present invention provides a concentrated crystallization device for N-methylformamide, which solves the problem that the structure of the existing concentrated crystallization device for N-methylformamide is too simple, has no buffer protection function, and cannot perform buffer reduction. Shock, isolation, etc., are easily affected by external force or external vibration, and the overall stability is poor, which is easy to interfere with the concentration and crystallization process, which is not conducive to the concentration of N-methylformamide, affects work efficiency, and reduces the problem of performance.

Description

technical field [0001] The invention relates to the technical field of concentration and crystallization equipment, in particular to a concentration and crystallization device for N-methylformamide. Background technique [0002] N-Methylformamide, a colorless transparent liquid, miscible with water and ethanol, has an ammonia smell, boiling point: 198-199°C (101.1kPa), it is mainly used as a raw material for organic synthesis, and is often used in the synthesis of medicines. At present, there are very few amide companies, especially because of product quality, amide products cannot be produced on a large scale. In recent years, the operating enterprises have undergone many optimizations and transformations, making N-methylformamide (NMF) industrially developed, especially widely used in the electronics industry. With the development of the electronics industry, the market demand for NMF will move forward steadily. In the production process of N-methylformamide, in order to ...
