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.
For example, in microelectronic grade industry, it is used in liquid crystal, semiconductor, circuit board, carbon nanotube and other high-end microelectronics industry.
In the electronics industry, it is applied to aramid fiber, PPS, ultra-filtration membrane, OLED panel photoresist etching and other industries. It can also be applied to the front-end solvent of lithium battery, which is the supporting solvent of lithium battery cathode binder.
In the industrial field, NMP can be used in acetylene extraction, butadiene extraction, electrical insulation materials, high-grade coatings, pesticide additives, inks, pigments, industrial cleaning agents and other industries.
In the pharmaceutical industry, NMP pharmaceutical grade has high safety requirements and is mainly used in medical, pharmaceutical, veterinary medicine, pharmaceutical intermediates and other industries.
It can be said that NMP is an important basic chemical raw material and an important raw material for the new energy industry.
As one of the main raw materials in the manufacturing process of lithium-ion batteries, NMP directly affects the quality of slurry coating and environmental protection requirements of lithium-ion batteries. According to the analysis of industry research data, although differences in models and specifications will lead to different proportions of NMP in the value of lithium-ion batteries, overall, NMP accounts for about 3%-6% of the manufacturing cost of lithium-ion batteries. The market for NMP The scale and demand also grow with the growth of lithium-ion batteries, especially energy storage batteries and power batteries.
In the production of lithium batteries, NMP is used to dissolve/swell PVDF and dilute the slurry. The moisture content is required to be low, and the content is generally above 99.9%.
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.
Avoid exposure: special instructions need to be obtained before use. Avoid contact with skin and eyes. Avoid inhalation of vapors and fumes. Keep away from sources of ignition. -Smoke and fire are strictly prohibited. Take measures to prevent static build-up.
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.
