NEP N-Ethylpyrrolidone

1、 Purpose:
N-Ethylpyrrolidone (NEP) is an organic synthesis intermediate used in various chemical synthesis and can also be used as an organic solvent. It is mainly used in the production of refined oil products, gunpowder, lithium batteries, pharmaceuticals, dyes, pesticides, daily chemicals, coatings, heat-resistant high molecular weight polymer resins, as well as dry rubber degreasing, coating unfolding agents, epoxy resin edge cutting, butadiene extraction, natural gas desulfurization, insecticides, synthetic fiber spinning media, pigment dispersion, etc.
Molecular formula: C6H11NO
Molecular weight: 113.16
2、 N-Ethylpyrrolidone (NEP) is a colorless and transparent liquid with weak alkalinity. Its boiling point is 82-83 ℃ (101.3Kpa), refractive index is N20d1.4665, and density is 0.994. It is a strongly polar organic solvent that can be miscible with water and general organic solvents in any ratio.
