2-pyrrolidone is a colorless crystals or liquid. Miscible with water, alcohols, chloroform, ether, ethyl acetate. Pyrrolidone is a keto-pyrrole, that is a 5-membered lactam structure compound (gamma-butyrolactam). By the chemical properties it is similar to carbon acid amides.
In industry 2-pyrrolidone is manufactured by the reaction of gamma-butyrolactone with NH3.
