What is Methylpyrrolidone? Methylpyrrolidone, also known as NMP or 1-methyl-2-pyrrolidone). NMP (N-Methylpyrrolidone) highly polar organic solvent used in a variety of industries and applications. Colorless transparent oily liquid with a slight amine odor. It is soluble with water, alcohols, ethers, esters, ketones, halogenated hydrocarbons, aromatic hydrocarbons and castor oil. Low volatility, thermal stability, chemical stability are good, can volatilize with water vapor. It has hygroscopic property. Sensitive to light. APPLICATION 1. Conductive pastes for lithium-ion battery and carbon nanotubes. 2. Acetylene concentration and extraction of butadiene, isoprene and aromatic hydrocarbons. 3. Lubricating oil refining. 4. Polymer solvents for insoluble engineering plastics (poly(p-phenylene sulfide) , polyimide) and aramid fibers. 5. High-grade paint, ink, pigment. 6.
