Hazard InformationBack Directory
[General Description]

A clear colorless liquid with a "fishlike" odor. Denser than water. Flash point 199°F. Contact may irritate skin, eyes and mucous membranes. May be toxic by ingestion.
[Reactivity Profile]

This amine is a very mild chemical base. N-METHYL-2-PYRROLIDONE(872-50-4) does tend to neutralize acids to form salts plus water. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.
[Air & Water Reactions]

Soluble in water.
[Health Hazard]

Inhalation of hot vapors can irritate nose and throat. Ingestion causes irritation of mouth and stomach. Contact with eyes causes irritation. Repeated and prolonged skin contact produces a mild, transient irritation.
[Fire Hazard]

Special Hazards of Combustion Products: Toxic oxides of nitrogen may be formed in fire.

[Chemical Properties]

1-Methyl-2-pyrrolidinone (NMP) has a molecular formula of C5H9NO, and it is a colorless to light yellow transparent liquid with a slight ammonia odor. Its boiling point is 204℃, flash point is 91℃, chroma HaZen≤25, refractive index N20D 1.468-1.471, density is 1.032-1.035. It is miscible in water at any ratio, it is soluble in ethanol, acetone, esters, halogenated hydrocarbons, aromatic hydrocarbons and other organic solvents, and it can completely mix with practically all solvents. It 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.
[Uses]

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 as a polyvinylidene fluoride solvent and electrode auxiliary material for lithium ion batteries. 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. It also has pharmaceutical uses. It is an excellent solvent, widely used in aromatics extraction, lubricating oil refining, acetylene enrichment, butadiene separation and synthesis gas desulfurization. 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.
