Author:


N-ethyl pyrrolidone is a strong polar organic solvent. It has the characteristics of high chemical stability, weak alkalinity, high solubility, low vapor pressure and low dielectric constant.

N-ethyl pyrrolidone can be used as highly selective solvent, catalyst and cationic surfactant. The product can be divided into the following two categories in practical application:

1. Industrial grade: used for the production of pyrrolidone series products, oil refining, gunpowder, coating, dye, heat-resistant high molecular weight polymer resin and dry adhesive degreasing, photoresist stripper, coating developer, epoxy resin edge removal, acetylene, butadiene extraction, natural gas desulfurization, synthetic fiber spinning medium, pigment dispersion, etc.  

2. Reagent grade: used in pharmaceutical and pesticide intermediates and daily cosmetics industries, as well as in the production of high-tech lithium batteries with high added value.
