N-Methyl-2-pyrrolidone

N-Methyl-2-pyrrolidone (NMP) is a clear, colorless to pale yellow liquid with a faint, characteristic odor and low volatility; it has a melting point of approximately −24 °C and a boiling point of 202–204 °C. It is a polar aprotic organic solvent and cyclic amide, classified as a heterocyclic compound. NMP is widely employed as a high-boiling, high-dipole-strength solvent in industrial processes, particularly for polymer dissolution, electronics cleaning, and lithium-ion battery electrode manufacturing. It serves as a key processing aid in the production of polyimides, aramids, and acrylic fibers, and is used in pharmaceutical synthesis, agrochemical formulation, and specialty coatings where strong solvency and thermal stability are required.

1-Methyl-2-pyrrolidinone (NMP) is a polar aprotic solvent that has the advantages of low toxicity, high boiling point, outstanding solvency, strong selectivity and good stability. It is widely used in purification of aromatic hydrocarbon extraction, acetylene, olefins, and diolefins.It is used in industrial cleaning, and it serves as a solvent for production of pesticides, engineering plastics, coatings, synthetic fibers, and integrated circuits.It can also be used as an industrial cleanser, dispersant, dye, lubricant and antifreeze.1-Methyl-2-pyrrolidinone is an excellent solvent, widely used in aromatics extraction, lubricating oil refining, acetylene enrichment, butadiene separation and synthesis gas desulfurization.It is used in gas desulfurization, lubricating oil refining, lubricating oil antifreeze, olefin extraction, and as a solvent for insoluble engineering plastics polymerization.It can be used in herbicide, to clean insulation materials, semiconductor industry precision instruments and circuit boards, to recycle PVC exhaust, as a detergent, dye supplement and dispersing agent.It is used in mediums for polymerization reactions such as engineering plastics and aramid fiber.1-Methyl-2-pyrrolidinone is used as a polyvinylidene fluoride solvent and electrode auxiliary material for lithium ion batteries.high purity grade for ICP-MS detection.For peptide synthesis.
1-Methyl-2-pyrrolidinone is also known as NMP, 1-methyl-2-pyrrolidone, N-methylpyrrolidone, and N-Methyl-2-pyrrolidone. NMP is a colorless to light yellow transparent liquid with a slight ammonia odor. NMP is completely miscible with water. It is highly soluble in lower alcohols, lower ketones, ether, ethyl acetate, chloroform, and benzene and moderately soluble in aliphatic hydrocarbons. NMP is strongly hygroscopic, chemically stable, not corrosive towards carbon steel and aluminum, and slightly corrosive to copper. It has low adhesiveness, strong chemical and thermal stability, high polarity, and low volatility. This product is slightly toxic, and its permitted concentration limit in air is 100ppm.
