N-methyl-2-pyrrolidone (nmp) is an organic compound consisting of a 5-membered lactam. It is a colorless liquid, although impure samples can appear yellow. It is miscible with water and with most common organic solvents. It also belongs to the class of dipolar aprotic solvents such as Dimethylformamide and dimethyl sulfoxide. It is used in the petrochemical and plastics industries as a solvent, exploiting its nonvolatility and ability to Titanium Dioxide dissolve diverse materials.
Nmp N-methyl-2-pyrrolidone Solvent is used to recover certain hydrocarbons generated in the processing of petrochemicals, such as the recovery of 1,3-butadiene and acetylene. It is used to absorb hydrogen sulfide from sour gas and hydrodesulfurization Solvent Raw Material facilities. Its good solvency properties have led to NMP's use to dissolve a wide range of polymers. Specifically, it is used as a solvent for surface Pvc Resin treatment of textiles, resins, and metal coated plastics or as a paint stripper. It is also used as a solvent in the commercial preparation of polyphenylene sulfide. In the pharmaceutical industry, N Methyl-2 Pyrrolidon is used in the formulation for drugs by both oral and transdermal delivery routes.
