N-Ethylpyrrolidone (NEP) is a colorless and transparent liquid with a boiling point of 82-83°C ( 101.3Kpa), a relative density of 0.994g/cm3 and a refractive index of 1.4665 ( 22°C). It is a strong polar organic solvent. It has high chemical stability, weak alkalinity, excellent solubility, low vapor pressure and low dielectric constant. It does not form hydrogen bonds and is a polar aprotic solvent. It can replace other solvents with poor stability, high vapor pressure and high toxicity and can easily penetrate into the skin. It is called a non-toxic supersolvent.
