Extractive distillation of 1‐propanol and 2‐propanol from the respective organo‐aqueous mixtures employing less soluble (Na IO 3 , K 2 SO 4 , PbCl 2 ) and sparingly soluble salts (Ca(OH) 2 , CaSO 4 , BaSO 4 , PbSO 4 , PbCO 3 ) dissolved to saturation in the boiling liquid phase at atmospheric pressure has been examined. The 98% purification of 2‐propanol obtained with Ca ++− , Pb ++ and Ba ++ salts suggests large perturbation of phase equilibria with relatively small salt concentrations (9 × 10 −6 M for Pb ++ ) on the 2‐propanol‐water system.
