Isobaric vapor-liquid equilibria for 1-propanol plus water plus lithium chloride at 100 kPa
Isobaric vapor-liquid equilibria for the ternary system 1-propanol + water + lithium chloride has been measured at 100 kPa using a recirculating still. The addition of lithium chloride to the solvent mixture produced an important salting-out effect over the alcohol and the azeotrope tended to be eliminated when the salt content increased, and two immiscible liquid phases were observed in a broad range of salt concentration. The experimental data sets were fitted with the electrolyte NRTL model and the parameters of Mock et al.'s model were estimated. This model has proved to be suitable to represent experimental data in the entire range of compositions. The effect of lithium chloride on the vapor-liquid equilibrium of the propanol + water system has been compared with that produced by other salts. (C) 2003 Elsevier B.V. All rights reserved.
