Henry's Law Constants have been calculated for nineteen selected VOC's from experimentally determined activity coefficients at infinite dilution and from extrapolated vapor-liquid equilibrium data. These data are all taken from the literature. The compounds studied include homologous series of alcohols, acids, aldehydes, and selected aromatics and ketones. The log of the HLC was empirically fit as a function of the reciprocal temperature, analogous to the relationship for several thermodynamic properties. The experimentally determined values of HLC's are correlated for each compound from 20 to 100°

The developed correlations provide the best available values of HLC's over the temperature range 20°

Henry's Law Constants estimated by UNIFAC, the Pierotti Method, and several solubility methods were compared with the experimentally determined values. UNIFAC was found to provide the best estimation of the HLC's. Solubility estimation methods gave only order of magnitude values. None of the estimation methods were satisfactory for the two aromatics studied.", pages = "43-69", url = "http://www.ingentaconnect.com/content/wef/wefproc/2000/00002000/00000003/art00004", doi = "doi:10.2175/193864700785303060" }
