Abstract
New experimental data regarding the solubility of 5-chloro-4-hydroxy-3-methoxybenzaldehyde and 4-chloro-2-methoxyphenol in water were obtained in the temperature range 280 to 363 K. The solubilities were measured by means of two techniques, namely high-performance liquid chromatography (HPLC) and total organic carbon (TOC). Considering the sparingly soluble 5-chloro-4-hydroxy-3-methoxybenzaldehyde, the aqueous infinite dilution activity coefficients were also obtained over the same temperature range by measuring the aqueous solubilities and the organics' enthalpies of fusion. The values of the infinite dilution activity coefficients ranged from 120 to 350 with an average relative deviation of 11%. The solubility−temperature dependence for both organics was well represented by conventional Van't Hoff relationships.
