N-Ethyl-2- Pyrrolidone(NEP) is one kind of strong polar organic solvent. Has the high chemical stability, the weak basicity, the high dissolving power,lowly steams characteristic and so on steam pressure and low coefficient of dielectrical loss. May serve as the highly effective selective solvent, the catalyst and the positive ion surface active agent

1,Industry Class: Uses in to produce the pyrrolidone series product, the oil quality purifies, the gunpowder, the coating, the dye, the heat-resisting macromolecular weight polymerization resin as well as does the rubber degreasing, the light sends the anti- etching reagent to strip the medicinal preparation, the coating launches the medicinalpreparation, epoxy side excises, the acetylene, the pyprolyleneextract, the natural gas desulphurization, synthetic fiber spinningmedium, pigment disperser and so on.

2,Reagent Calss: Uses in the medicine, the agricultural chemicals intermediate and the everyday use cosmetics profession, as well as produces profession and so on high tech attachment value high lithiumbattery
