摘要：
Olefins and paraffins are important basic chemical raw materials with so similar molecular structure and volatility that their separation is a difficult and energy-consuming process. Liquidliquid equilibrium (LLE) data were determined for ternary systems of: 1-hexene + hexane + solvent at 25 degrees C, 30 degrees C, and 35 degrees C, and N-formylmorpholine (NFM), N-methyl-2-pyrrolidone (NMP), gamma-butyrolactone (GBL), and 1-methylimidazole (1-MEI) as the solvents studied. Liquid-liquid equilibrium data for each system were correlated to the NRTL (Non-Random Two Liquid) equation and the interaction parameters presented. The calculated results agree well with the experimental data. (c) 2015 Institute of Chemistry, Slovak Academy of Sciences
