N-methylpyrrolidone (NMP) is an important organic solvent with the following physical and chemical properties:Chinese name: N-methylpyrrolidone English name: N-methylpyrrolidin-2-one Chinese alias: 1-methyl-2-pyrrolidone | n-methyl-pyrrolidone | 1-methyl-2-pyrrolidone | n-methyl-a-pyrrolidone | methyl-pyrrolidone | 1-methyl-pyrrolidone | 1-methyl-pyrrolidone CAS Number: 872-50-4 Density: 1.0± 0.1g /cm3 Boiling point: 202.0±0.0 °C at 760 mmHg Melting point: −24 °C(lit.) Molecular formula: C5H9NO Molecular weight: 99.131 Flash point: 86.1±0.0 °C Accurate mass: 99.068413 PSA: 20.31000 LogP: -0.40 Vapor density :3.4 (vs air) Vapor pressure :0.3±0.4 mmHg at 25°C Refractive index :1.470 Storage: In the presence of dry inert gas, keep the container sealed and store in a cool, dry place. 1. Appearance: N-methylpyrrolidone is a colorless and transparent liquid. 2. Boiling point: N-methylpyrrolidone has a boiling point of about 202°C, so it is a less volatile liquid at room temperature. 3. Density: The density of N-methylpyrrolidone is about 1.03 g/cm³, which is slightly heavier than water. 4. Solubility:…
