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.

N vinyl 2 pyrrolidone nmp. It is used to absorb hydrogen sulfide from sour gas and hydrodesulfurization facilities. N methyl 2 pyrrolidone nmp is used to recover certain hydrocarbons generated in the processing of petrochemicals such as the recovery of 1 3 butadiene and acetylene. Due to its good solvency properties n methyl 2 pyrrolidone nmp is used to dissolve a. For pharmaceuticals cosmetics and food additives or copolymers used as viscosity improvers in oils and in water borne paints and adhesives.

2 pyrrolidone s production and use as a precursor to n vinyl 2 pyrrolidone may result in its release to the environment through various waste streams. 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. N methyl 2 pyrrolidone nmp is a high boiling polar aprotic low viscosity liquid.

If released to air a vapor pressure of 9 49x10 3 mm hg at 25 c indicates 2 pyrrolidone will exist solely in the vapor phase in the ambient atmosphere. The majority of the n vinyl pyrrolidone n vp that is sold within the eu is used in the production of polyvinyl pyrrolidone e g. N vp is also used as a reactive thinner in uv cured inks and lacquers.
