НЭП N-этил-2-пирролидон

N-Ethyl-2-Pyrrolidone, NEP, N-EthylpyrrolidoneFomula: C6H11NOCAS No.: 2687-91-4Discription: N-ethylpyrrolidone (NEP) is the lactam of 4-ethylaminobutyric acid and a very weak base. NEP is a chemically stable and powerful polar solvent. These characteristics are highly useful in a variety of chemical reactions where an inert medium is of concern. Despite the stability of NEP, it can also play an active role in certain reactions: Hydrolysis, oxidation, condensation, conversion with chlorinating agents, polymerization and o-alkylation, and related reactions.Specifications: Appearance: Clear, colorless liquid APHA: 50 max.
