Applications of N-Methyl-2-pyrrolidone (NMP)
N-Methyl-2-pyrrolidone (NMP) is a highly polar, aprotic solvent with excellent solvency for a wide range of organic and inorganic compounds. It is a colorless to light yellow liquid with high boiling point, low volatility, and strong dissolving power, making it essential in various advanced industrial processes.
Key Application Areas:
1.Petrochemical and Refining Industry
Used as a selective solvent in extraction processes such as BTX (benzene-toluene-xylene) recovery and lube oil purification.
Enhances yield and purity in aromatics separation.
2.Electronics and Semiconductor Manufacturing
Serves as a photoresist stripper and cleaning agent in microelectronics and display panel production.
Used in lithium-ion battery production as a solvent for PVDF binders in cathode/anode formulations.
3.Pharmaceutical Industry
Acts as a process solvent and crystallization aid in the synthesis of active pharmaceutical ingredients (APIs).
Its excellent solubilizing ability improves drug formulation efficiency.
4.Coatings and Paints
Used as a high-performance solvent in polyurethane, epoxy, and acrylic coatings, particularly in automotive and industrial finishes.
Offers controlled evaporation and good flow characteristics.
5.Polymer and Plastic Processing
A solvent and carrier in the production of polyimides, polyurethanes, and other engineering plastics.
Helps dissolve and process high-performance polymers.
6.Adhesives and Sealants
Improves flow and open time in high-performance adhesive systems, including heat-seal and film-lamination adhesives.
7.Agrochemicals
Used as a co-solvent and carrier in formulations of pesticides, herbicides, and fungicides, enabling uniform dispersion and penetration.
8.Cleaning and Degreasing
Effective in removing oils, greases, fluxes, and residues from metal parts, machinery, and optical components.
Key Benefits:
Strong solvency for both polar and non-polar substances
High boiling point and thermal stability
Miscible with water and most organic solvents
