（6）fromN-From the physical properties of methylpyrrolidone, we can see that it has many advantages, such as high boiling point, low vapor pressure, low toxicity, good solubility, etc. It can be used as a solvent for polymer reactions;

（7）Compared with phenol and furfural,N-Methyl pyrrolidone has the characteristics of strong polarity, non-toxicity, non-corrosiveness, and easy recovery. It has replaced phenol and furfural to remove aromatic substances from lubricating oil. This process is safe and reliable, with low solvent loss.

（8）Recover acetylene, butadiene, pentadiene and other gases from naphtha cracking gas;

（9）It can be used to wash blockages and attachments in chemical equipment such as towers and kettles, and high concentrationN-Methylpyrrolidone is also used as an ultrasonic cleaning agent for precision machinery and optical instruments;

（10）It is the production of artificial plasma and vitaminsB1The main raw material.
