Abstract Isobaric vapor–liquid equilibria for the binary systems 1-propanol+lithium nitrate and water+lithium nitrate and the ternary system 1-propanol+water+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 tends to disappear when the salt content increases. The two experimental binary data sets were independently fitted with the electrolyte NRTL model and the parameters of Mock’s model were estimated for each binary system. These parameters were used to predict the ternary vapor–liquid equilibrium using the same model and the values so obtained agreed well with the experimental ones.
