1-этил-2-пирролидинон химические свойства, назначение, производство
Химические свойства
N-Ethyl-2-pyrrolidone (NEP) is a colorless, clear liquid that serves as a low-volatility aprotic solvent classified as a reproductive toxicant. It is characterized by high solvency, low vapor pressure, and a low dielectric constant.
Использование
1-Ethyl-2-pyrrolidone was used to modify coir fiber (from Cocos nucifera) by photocuring.
прикладной
N-Ethyl-2-pyrrolidone is commonly used as a solvent. It has a low boiling point, which makes it suitable for use in low light and at constant pressure. It is also used as an intermediate in the preparation of polycarboxylic acid. It has been shown to be involved in both viscosity and hydrogen bonding.
Общее описание
1-Ethyl-2-pyrrolidone is a transdermal absorption-enhancing compound and mechanism of its effect on multilammellar liposome of stratum corneum lipid has been studied.
Побочные эффекты
