N-Methyl-2-pyrrolidone abbreviated as NMP, is a colorless to light yellow transparent liquid, slightly ammonia odor, miscible with water in any proportion, soluble in ether, acetone and esters, halogenated hydrocarbons, aromatic hydrocarbons and other organic solvents, and almost all solvents are completely mixed. It is relatively stable in neutral solution; it is gradually hydrolyzed in concentrated hydrochloric acid to produce 4-methylaminobutyric acid.
N-Methyl-2-pyrrolidone is a polar non-proton transfer solvent. It has low toxicity, high boiling point and outstanding solvency. The advantages of high selectivity and good stability. Widely used in aromatics extraction, purification of acetylene, olefin, diolefin, solvent of polyvinylidene fluoride, electrode auxiliary material of lithium ion battery, syngas desulfurization, lubricant refining, lubricant antifreeze, olefin extractant, solvent in polymerization of insoluble engineering plastics, insulating material, integrated circuit production, semiconductor industry, precision instruments, washing of circuit boards, PVC tail gas recovery, cleaning agent, dye auxiliary agent, Dispersant, etc.
It is also used as a solvent for polymers and a medium for polymerization reactions, such as engineering plastics and aramid fibers.
It can also be used in pesticides, pharmaceuticals and cleaning agents.
