N-Methylpyrrolidone

　　Main Applications

　　NMP is widely used due to its strong solvency and stability:

　　Electronics Industry:

　　As a solvent for lithium battery electrode materials, it is used to dissolve binders such as polyvinylidene fluoride (PVDF) and prepare electrode slurries (applicable to both cathodes and anodes), making it one of the key solvents in lithium battery production.

　　Used for cleaning electronic components and photoresist residues on semiconductor chips, or as a cleaning agent for liquid crystal displays (LCDs). Chemical Industry and Extraction:

　　As an extractant, it is used for the separation of aromatics and aliphatics (e.g., extracting benzene and toluene from petroleum fractions) and the recovery of organic gases (e.g., acetylene, butadiene).

　　As a polymer solvent, it is used for synthesizing polymer materials such as polyimides and polyamides, or for preparing coatings and adhesives (adjusting viscosity after dissolving resins).

　　Pharmaceuticals and Fine Chemicals:

　　As a reaction solvent for organic synthesis (e.g., catalytic reactions, cyclization reactions), it is particularly suitable for reactions involving polar compounds.

　　Used for the purification of pharmaceutical intermediates (crystallization and separation after dissolving the target product).

　　Other Fields:

　　In the textile industry, it serves as a dye solvent to improve the penetration of dyes into fibers;

　　As a cleaning agent, it is used to remove difficult-to-dissolve impurities such as grease and wax.
