Pyrrolidin-2-one, often called pyrrolidone, is the lactam of 4-aminobutyric acid. Pyrrolidone is prepared from butano-4-lactone and ammonia at 250°C. It is colourless, water-soluble, of mp 25°C and bp 250°C (decomp). Pyrrolidone is vinylated by acetylene. Poly-(A -vinylpyrrolidone) has proved useful as a plasma substitute in blood transfusion.
