| N-Methyl-2-Pyrrolidone (NMP)
 Odor: characteristic Use: 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.  |

 Odor: characteristic Use: NMP is used to recover certain hydrocarbons generated in the processing petrochemicals, such as the recovery of 1,3-butadiene and acetylene. It is used to absorb hydrogen sulfide from sour gas and hydrodesulfurization facilities. Due to its good solvency properties NMP is used to dissolve a wide range of polymers. It also used as a solvent for surface treatment of textiles, resins, and metal coated plastics or as a paint stripper.  |
