Chemical name: N-methyl-2-pyrrolidone; 1-methyl-2-pyrrolidone; Nitro-methylpyrrolidone.CAS NO. : 872-50-4Subtype: C5H9NO   English name: N-methyl-2-pyrrolidoneDescription: N-methylpyrrolidone (NMP), a nitrogen heterocyclic compound, molecular formula C5H9NO, boiling point 204°C, a slightly ammoniacal flavor of the liquid, miscible with water in any proportion, almost with all solvents (ethanol, acetaldehyde, ketone, aromatic hydrocarbons, etc.) completely mixed. NMP is a polar aprotic transfer solvent with high boiling point, strong polarity, low viscosity, strong dissolution ability, no corrosion, little toxicity, strong biodegradation ability, low volatility, excellent chemical stability and thermal stability.Production process: NMP industrialization time is long, the technology is mature, its production process from 1,4 butanediol (BDO) dehydrogenation to produce gamma-butanolactone (GBL), and then gamma-butanolactone and monomethylamine amination reaction to produce products, then distillation and purification to finished NMP. Application field N-methylpyrrolidone is an excellent advanced solvent, which is used in petrochemical, pesticide, medicine, electronic materials and other fields. It can be used as acetylene concentration, syngas…

NMP is one of the most commonly used accessories for lithium batteries. NMP is the solvent of PVDF binder, is the English abbreviation of N-methylpyrrolidone, a colorless transparent liquid, with low toxicity, high boiling point, strong polarity, low viscosity, strong solubility, chemical stability, excellent thermal stability and other characteristics, can be miscible with water, PVDF, positive and negative electrode materials, etc., widely used in the preparation of lithium batteries. When making electrode sheets, NMP is used as a solvent to fuse various materials required for electrodes, such as binder, positive active substance, conductive agent, etc., so that the binder is fully in contact with other substances and evenly distributed. As a solvent, the quality of NMP directly affects the quality of pulping coating of lithium-ion batteries, which is an indispensable solvent material. From the perspective of the distribution of NMP application fields, it is mainly used in the preparation of…
