N-Methyl-2-Pyrrolidone (NMP) is a high boiling, polar aprotic, low viscosity liquid. NMP has a good solvency for a wide range of organic and inorganic compounds and it is miscible with water at all temperatures and has a high chemical and thermal stability. It is used as a solvent for engineering polymers and coating resins. The polar nature and the low surface tension of NMP makes it also an excellent cleaning medium and paint stripping solvent.
NMP is a powerful solvent with a low volatility used for a wide range of chemicals and finds its application among others in:
NMP is used as extraction medium in several industrial processes because of its affinity for unsaturated hydrocarbons and aromatics, for example butadiene recovery, BTX extraction, lube oil purification, ...
