N-methyl pyrrolidone

Other name: 1-Methyl-2pyrrolidone CAS NO:872-50-4 MF: C5H9HO

EINECS No.: 212-828-1 Melting point: -24.4℃ Boiling point: 203℃ Relative density: 1.0260 Refractive index: 1.486 Flashing point: 95℃

Characteristics: Colorless and transparent liquid, with boiling point 202 and flash point 95, can dissolvable in water and many solvents, such as acetaldehyde, ether, acetone, etc.

Usage: NMP is widely used in senior lubricating oil refining, polymers, synthesis, insulation materials, pesticide, printing ink, high-grade coatings, pigments and cleaner (deoiling, degreasing, dewaxing, polishing, antirust and depainting) etc, also applied to artificially kidney function membrane fluid and seawater desalination membrane fluid.

As a high-selective solvent, NMP has such advantages as non-toxicity, high boiling point, low corrosion, high solubility, low viscosity, low volatility and good stability and easy to recovery. It is mainly used in electronic industry in the following aspects:

(1) As solvent of poly(1,1-difluoro-Ethene); or electrode's accessory material of lithium ion battery. (2)As remover liquid of photoresist; in the production of LCD materials; (3)As solvent in pharmacy; (4)Cleaning of precision instruments and circuit board (5) Concentrate of ethylene and extracting of butadiene, isoprene, aren, etc.
