Abstract

The effect of five dissolved inorganic salts, namely; aluminum chloride, calcium chloride, potassium chloride, potassium nitrate, and potassium bromide, on the vapor liquid equilibria (VLE) of the binary system propionic acid-water was investigated at 60 °C using the headspace gas chromatography technique (HSGC). For various salt concentrations, the influence of the salting out of propionic acid was noted. For a concentration of 1.0 molality (m) it was found that the trivalent cation salt ( AlCl₃) had the greatest effect on the salting out followed by the bivalent cation salt (CaCl₂) and lastly the univalent cation salts (KCl, KNO₃, KBr). Greater salting-out was achieved when the concentration of AlCl₃ or CaCl₂ was increased from 0.2 to 1.5 m. The experimental VLE data was fitted into the modified Furter's equation, recently proposed by Wu et al., and a correlation proposed by Subbaiah. Deviations and parameters are reported.
