2-pyrrolidone

2-pyrrolidone is a colorless clear liquid, a high boiling polar solvent and an intermediate for organic synthesis. It is mainly used as a solvent for synthetic resins, pesticides, polyols, inks and iodine. It is also a raw material for the production of polyvinylpyrrolidone, nylon-4 and brain rehabilitation.
