In this study, the vapor pressures of aqueous solutions of three organic salts, benzyltrimethylammonium chloride, benzyltriethylammonium chloride, and benzyltributylammonium chloride, were measured from 298.15 K to 333.15 K, and the enthalpies of vaporization were estimated by the Clausius-Clayperon equation. The concentrations of salts ranged from 0.5 m (mol . 1000 g solvent(-1)) to saturation depending on the solubility of the salt.
