SOLUBILITIES OF SODIUM-CHLORIDE IN ORGANIC AND AQUEOUS-ORGANIC SOLVENT MIXTURES

The solubility of sodium chloride in the binary organic or aqueous-org anic solvent mixtures methanol + cyclohexane, water + cyclohexanol, an d water + benzyl alcohol as well as in the ternary mixtures water + (e thanol or benzyl alcohol) + cyclohexanol at 298.15 K and ambient press ure has been determined using a gravimetric method. The reliability of the measuring principle has been tested by comparing the solubilities of sodium chloride in methanol, ethanol, and (methanol + cyclohexane) to literature values. The data for the system methanol + cyclohexane + sodium chloride, which were measured over the whole concentration ra nge of the solvent mixture, have been fit to a concentration-dependent expression.
