摘要：

Liquid-liquid equilibrium data for the quaternary system water-ethanol-2-ethylhexanol-sodium chloride have been determined experimentally at 25 degrees C. The data obtained make it possible to carry out the design calculation of a proposed suitable extraction process for separating ethanol and water using 2-ethylhexanol as the solvent when sodium chloride is added. The analysis of the process shows that the advantages that the salt addition offers to the extraction and recovery of the ethanol are presently limited.
