ABSTRACT

Isobaric vapor liquid equilibria for the ternary system acetone + methanol + lithium nitrate have been measured at 100 kPa using a recirculating still. The addition of lithium nitrate to the solvent mixture produced an important salting-out effect and the azeotrope tended to disappear for small contents of salt. The experimental data sets were fitted with the electrolyte NRTL model and the parameters of the Mock s model were estimated. These parameters were used to predict the ternary vapor liquid equilibrium which agreed well with the experimental one.
