Measurement and correlation of liquid-liquid equilibrium for the ternary system(water+1,2-dichloroethane+sulfolane)at 288.15,298.15,and 308.15 K
文献摘要：
Sulfolane is an important aprotic polar solvent.Liquid-liquid equilibrium(LLE)data for the ternary sys-tems of water+1,2-dichloroethane+sulfolane were measured at temperatures of 288.15,298.15 and 308.15 K under the atmospheric pressure.The distribution coefficient and selectivity were determined from the measured LLE data,which showed that 1,2-dichloroethane is a suitable extractant for the recov-ery of sulfolane from its aqueous solution.The nonrandom two-liquid(NRTL)model and the universal quasi-chemical(UNIQUAC)model were utilized to correlate the experimental LLE data.The low values of RMSD indicated that the ternary system could be fitted well by the NRTL and UNIQUAC models.The consistency of the binary interaction parameters for the two thermodynamic models obtained was con-firmed by the topological information contained in the Gibbs energy of mixing function(GM/RT).
