1-Methyl-2-pyrrolidinone Usage 
  1. 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.
  2. It is used in industrial cleaning, and it serves as a solvent for production of pesticides, engineering plastics, coatings, synthetic fibers, and integrated circuits.
  3. It can also be used as an industrial cleanser, dispersant, dye, lubricant and antifreeze.
  4. 1-Methyl-2-pyrrolidinone is an excellent solvent, widely used in aromatics extraction, lubricating oil refining, acetylene enrichment, butadiene separation and synthesis gas desulfurization.
  5. It is used in gas desulfurization, lubricating oil refining, lubricating oil antifreeze, olefin extraction, and as a solvent for insoluble engineering plastics polymerization.
  6. 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.
  7. It is used in mediums for polymerization reactions such as engineering plastics and aramid fiber.
  8. 1-Methyl-2-pyrrolidinone is used as a polyvinylidene fluoride solvent and electrode auxiliary material for lithium ion batteries.
  9. high purity grade for ICP-MS detection.
  10. For peptide synthesis.
