Overview
2-Pyrrolidinone (CAS: 91-16-5), molecular formula C4H7NO, is a cyclic amide produced via carbonylation of gamma-butyrolactone. It serves as a high-polarity, non-toxic solvent widely used in industrial synthesis.
Application
- Polymer manufacturing for polyvinylpyrrolidone (PVP) resins.
- Extraction of aromatic hydrocarbons and olefins from petroleum.
- Solvent medium for pharmaceutical intermediates and agrochemicals.
Precautions
Maintain storage below 30°C in dry, ventilated areas away from strong oxidizers. Use appropriate PPE to prevent skin absorption; avoid inhalation of vapors during processing.
