Product application: N-methylpyrrolidone (NMP) is a polar aprotic solvent. It has low toxicity, high boiling point and outstanding dissolving power. The advantages of strong selectivity and good stability. Widely used in aromatic hydrocarbon extraction, purification of acetylene, olefin, diene, solvent of polyvinylidene fluoride, electrode auxiliary material of lithium ion battery, synthesis gas desulfurization, lubricating oil refining, lubricating oil antifreeze, olefin extracting agent, Solvents used in the polymerization of insoluble engineering plastics, agricultural herbicides, insulation materials, integrated circuits, semiconductor industry precision instruments, circuit board cleaning, PVC tail gas recovery, cleaning agents, dye additives, dispersants, etc. It is also used as a solvent for polymers and as a polymerization medium, such as engineering plastics and aramid fibers. It can also be used in pesticides, medicines and cleaning agents. Its main uses are as follows:
1. Concentration of acetylene and extraction of butadiene, isoprene, aromatic hydrocarbons, etc.
2. Refining of lubricants
3. Polymer solvents for insoluble engineering plastics (polyphenylene sulfide, polyimide) and aramid fibers
4. Electronic insulation materials, lithium ion batteries
