Basic chemical series--N-methylpyrrolidone (NMP)


Release time:

2023-11-10

Chemical name: N-methyl-2-pyrrolidone; 1-methyl-2-pyrrolidone; nitrogen-methylpyrrolidone.
CAS NO.:872-50-4
Molecular formula: C5H9NO

English name: N-methyl-2-pyrrolidone
Properties: N-methylpyrrolidone (NMP for short) is a nitrogen heterocyclic compound with a molecular formula of C5H9NO and a boiling point of 204°C. It is a liquid with a slight ammonia smell. It is miscible with water in any proportion and is compatible with almost all solvents (ethanol). , acetaldehyde, ketones, aromatic hydrocarbons, etc.) are completely mixed.

NMP is a polar aprotic solvent with high boiling point, strong polarity, low viscosity, strong solubility, non-corrosion, low toxicity, strong biodegradability, low volatility, excellent chemical stability and thermal stability.

Production process: NMP has been industrialized for a long time and the technology is mature. Its production process consists of dehydrogenating 1,4-butanediol (BDO) to produce γ-butyrolactone (GBL), and then amination of γ-butyrolactone and monomethylamine. The reaction generates products, which are then distilled and purified into the finished product NMP.

Application areas:

N-Methylpyrrolidone is an excellent high-grade solvent used in petrochemicals, pesticides, medicines, electronic materials and other fields. It can be used as acetylene concentration, syngas desulfurization, lubricating oil refining, lubricating oil antifreeze, olefin extraction agent, solvent in the polymerization of insoluble engineering plastics, agricultural herbicides, insulation materials, integrated circuit production, PVC exhaust gas recovery, cleaning agents, dye auxiliaries, dispersants, etc.

Purpose:
Microelectronic grade: used in high-end microelectronics industries such as liquid crystals, semiconductors, and circuit boards.
Electronic grade: used in lithium batteries, aramid fiber, PPS, ultrafiltration membrane and other industries.
Pharmaceutical grade: used in medicine, medicine, veterinary solvents, intermediates and other industries
Industrial grade: used in acetylene concentration, butadiene extraction, electrical insulation materials, high-end coatings, pesticide additives, inks, pigments, industrial cleaning agents and other industries.
Storage methods and precautions:

1. Storage method

Store in a cool, dry place under dry inert gas, and keep the container sealed.

2. Operation precautions

Avoid exposure. Require specific instructions before use. Avoid contact with skin and eyes; avoid inhalation of steam and smoke; keep away from fire sources; strictly prohibit fireworks; take measures to prevent the accumulation of static electricity.

3. Storage precautions
