It is produced industrially by vinylation of 2-pyrrolidone, i.e. the base-catalyzed reaction with acetylene.[2] 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.[2]
Synthesis
editStarting from γ-Butyrolactone, 2-pyrrolidone is synthesized by treatment with ammonia.[3] Subsequently, acetylene is used to introduce the vinyl group.[2][4]
