N-Methyl-2-Pyrrolidone (NMP)

Description

What is N-Methyl-2-Pyrrolidone (NMP)?

N-Methyl-2-Pyrrolidone (NMP) is a high-performance, polar aprotic solvent known for its excellent solvency and chemical stability. With the molecular formula C₅H₉NO, NMP is widely used in chemical processes requiring strong solubilizing power, high thermal stability, and slow evaporation rates. This versatile liquid finds applications across pharmaceuticals, electronics, petrochemicals, and polymers.

As a slow-evaporating, high-boiling solvent, NMP plays a crucial role in reactions such as oxidation, condensation, and chlorination. Its unique characteristics make it ideal for dissolving a wide range of polymers, extracting hydrocarbons, and formulating coatings and adhesives.

Chemex Chemicals is a leading importer and supplier of N-Methyl-2-Pyrrolidone (NMP) in India, delivering consistent quality for industrial applications.

Key Applications of N-Methyl-2-Pyrrolidone (NMP)

• Petrochemical Processing

NMP is widely used as an extractive solvent in petrochemical industries, particularly for recovering 1,3-butadiene, acetylene, and other hydrocarbons during distillation processes.

• Gas Desulfurization

It effectively absorbs hydrogen sulfide (H₂S) and other sulfur-containing compounds in natural gas and synthetic gas, making it valuable for environmental control in refineries and power plants.

• Polymer & Resin Processing

Due to its broad solvency range, NMP is employed to dissolve engineering plastics such as polyvinylidene fluoride (PVDF), polyimide, and polyphenylene sulfide (PPS). It’s commonly used in the manufacture of lithium-ion batteries for preparing electrode coatings.

• Pharmaceutical Industry

NMP serves as a solvent and carrier in pharmaceutical formulations, including oral and transdermal drug delivery systems. Its chemical compatibility makes it suitable for a variety of active pharmaceutical ingredients (APIs).

• Paint Stripping & Coating Removal

Owing to its slow evaporation and high solvency, NMP is widely used in paint removers, coating strippers, and surface treatment processes in automotive and metal industries.

Features & Benefits
