N-Methylpyrrolidone (NMP) is an aprotic, highly polar organic solvent that is used in a variety of industries in chemical, resin plastic, coating, ink, dye, pesticide, lithium-ion battery, electronics and other industries. The applications mainly include:
- Peptide synthesis in the pharmaceutical industry
- Membrane manufacture, for example, polyvinylidene fluoride (PVDF), polyvinylpyrrolidone (PVP) and polyether sulfone (PES).
- Lithium ion battery production
- Coatings, inks and resins
- Crop protection formulations and active ingredient synthesis
- Oil extraction processes
NMP full name is N-Methyl-2-pyrrolidone, colorless transparent oily liquid with slight amine odor, can be widely used in chemical, resin plastic, coating, ink, dye, pesticide, lithium-ion battery, electronics and other industries. According to the different product grades.
N-Methyl-2-pyrrolidone (NMP) is a highly polar aprotic solvent with a high boiling point, strong polarity, low viscosity, strong solvency, non-corrosive, low toxicity, good chemical and thermal stability, and completely compatible with Water miscibility and other advantages, mainly used in coatings, lithium batteries, plastics, chemical production agents, agricultural chemicals, cleaning, cleaning and degreasing, polymer solvents and polymerization solvents and other fields.
NMP currently has three production process types:
A kind of pyrrolidone method using pyrrolidone and halogenated alkanes as raw materials,
The second is to synthesize NMP under catalyst conditions,
Three are the GBL method of γ-butyrolactone and mixed methylamine or monomethyl amine as raw materials.
At present, the mixed GBL method of γ-butyrolactone and monomethyl amine aqueous solution is mostly used.
The GBL method is to mix γ-butyrolactone and monomethyl amine aqueous solution in a tubular mixer, preheat it through a tubular preheater and heat it in the column at a high temperature of 260-290°C and a pressure of 7.5-8.5Mpa. 1.5-2.0 hours of reaction in a tubular reactor.

NMP recovery system can achieve green and safe discharge without any modification to the production equipment, which not only solves the problem of environmental protection, but also brings considerable economic benefits to the enterprise. Zesheng NMP recovery system has a simple structure and is easy to install.
Store in a cool place. Keep containers tightly closed and store in a dry, ventilated place. Opened containers must be carefully resealed and kept in an upright position to prevent leakage. Store air-filled and humidity sensitive.
