Product Name:2-Pyrrolidinone
English Name:2-Pyrrolidinone
CAS No.:616-45-5
Aliases:alpha-Pyrrolidinone
Molecular Formula:C4H7NO
Physical Properties:Appearance: liquid or low-melting solid; Melting point: 23-25°C; Boiling point: 245°C; Density: 1.12 g/mL at 25°C; Refractive index: 1.487 (20°C); Flash point: >110°C; Solubility: miscible with water; pH: 9-11 (100 g/L in water, 20°C); Vapor pressure: 0.04 hPa (20°C); Vapor density: 2.9 (vs air); Hygroscopic; Storage: 2-8°C.
Uses:2-Pyrrolidinone is an important organic synthesis intermediate used in the production of nylon-4 and vinylpyrrolidone (NVP), which can be further polymerized to polyvinylpyrrolidone (PVP). It is also widely used as a solvent for synthetic resins, pesticides, polyols, and inks, as well as a plasticizer for acrylic resins, an extractant for aromatic compounds, and a decolorizer for kerosene, rosin, and fatty acids.
