Product Features

N-Ethyl-2-pyrrolidone is produced with gamma-butyrolactone and ethylamine as raw materials through an advanced catalytic cyclization reaction, with high reaction selectivity and minimal by-product generation, realizing continuous and green industrial production with low three wastes discharge. The product adopts independently developed deep purification, dewatering and deodorization refining technology, with a purity of more than 99.9%, ultra-low water content and impurity content, and no irritating odor. Its volatility is lower than that of similar pyrrolidone solvents, and it has outstanding thermal and chemical stability, without decomposition, discoloration or hydrolysis under normal storage and high-temperature use conditions (≤220℃). It has excellent solubility for most organic compounds, inorganic salts and high polymers, and the dissolved system has good stability. The whole production process is controlled by an automatic DCS system, and all batches of products are detected by advanced analytical instruments such as GC and GC-MS to ensure the consistency and stability of product quality, with all indicators superior to national industrial grade standards.
