Abstract
Henry's constants of the homologous series of 2-ketones from 2-propanone to 2-heptanone were measured in aqueous solutions containing sodium chloride from (0.2 to 1.2) m (molal) over a range of temperatures from (313 to 363) K. In addition, Henry's constants of the n-alkanols from ethanol to 1-hexanol in aqueous solutions with sodium sulfate from (0.2 to 1.2) m were also measured over the same temperature range. The data were correlated using a model based on dilute solution theory that contains one temperature-independent salt effect parameter. A linear relationship between this parameter and the critical volume of the volatile organic compound (VOC) was found for each homologous series studied in this work.
