N-Methyl-Pyrrolidone

Superiority:

Molecular Formula : C5H9NO

Physical properties: N-Methyl-Pyrrolidone is a colorless transparent liquid with a faint amine ordor. It has strong water absorption. NMP is miscible with water and conventional organic solvents. As a high-selective polar solvent and nitrogen heterocycle compound, NMP has such advantages as non-toxicity, high boiling point, low corrosion, high solubility, low viscosity, low volatility and good stability and high selectivity.
