General description
N-Methyl-2-pyrrolidinone (N-methylpyrrolidone, NMP) is a polar cyclic organic solvent. A study on the impact of NMP on Saccharomyces cerevisiae revealed that it induced aneuploidy. Characteristic properties of NMP include low viscosity, excellent dissolving power and enhanced demulsifying property. It is a better alternative to phenol in selectively treating lube feedstock. The behavior of fullerene-C60 in NMP solution has been examined based on electronic absorption and photoluminescence spectral data. A solution of sodium borohydride (NaBH4) in NMP showed increased reactivity towards debromination of alkyl bromide. The enhanced selectivity of NMP-ethylene glycol solvent mixture for aromatic hydrocarbon extraction has been analyzed by gas chromatography.
