N-Vinylpyrrolidone (NVP) is an organic compound consisting of a 5-membered lactam ring linked to a (2 carbon) vinyl group. It is a colorless liquid although commercial samples can appear yellowish.
It is produced industrially by vinylation of 2-pyrrolidone, i.e. the base-catalyzed reaction with acetylene. It is the precursor to polyvinylpyrrolidone (PVP), an important synthetic material. The NVP monomer is commonly used as a reactive diluent in ultraviolet and electron-beam curable polymers applied as inks, coatings or adhesives.
Synthesis
Starting from γ-Butyrolactone, 2-pyrrolidone is synthesized by treatment with ammonia. Subsequently, acetylene is used to introduce the vinyl group.
