What industries can NMP be used in?
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.
Other areas where NMP is used include.
1, Polymer industry, NMP is present as a solvent for the polycondensation reaction of para-aramids.
2、 Insulation material industry, NMP is used as reaction and dilution solvent of polyimide varnish in insulation material industry.
3、 Electronic materials industry, NMP is used in electronic materials for IC, PCB, LED, semiconductor cleaning, mainly as ultra-pure electronic chemicals.
4、 Petrochemical industry, such as butadiene extraction, isoprene extraction, desulfurization of synthesis gas, acetylene recovery, lubricating oil refining, etc.
N-Methylpyrrolidone (NMP) is a highly polar nonproton transfer solvent with high boiling point, strong polarity, low viscosity, strong solvency, non-corrosive, low toxicity, good chemical and thermal stability, and is completely miscible with water.
and completely miscible with water, etc.
It is mainly used in the fields of coatings, lithium batteries, plastics, chemical production agents, agricultural chemicals, removal, cleaning and degreasing, polymer solvents and polymerization reaction solvents.

Bust the myths behind electric vehicles.
There are three types of production processes for NMP.
One is the pyrrolidone method, which uses pyrrolidone and halogenated alkanes as raw materials.
The second is the synthesis of NMP under catalyst conditions.
The third is the GBL method, which is based on γ-butyrolactone and mixed methylamine or monomethylamine.
At present, the GBL method is mostly based on the mixture of γ-butyrolactone and monomethylamine in aqueous solution.
GBL method is generated by mixing γ-butyrolactone and monomethylamine aqueous solution in a tubular mixer, preheated by a tubular preheater, and reacted in a tubular reactor for 1.5-2.0 hours at a high temperature of 260-290℃ and a pressure of 7.5-8.5Mpa.
