Table entries are sorted according to reliability of the data, listing the most reliable type first: L) literature review, M) measured, V) VP/AS = vapor pressure/aqueous solubility, R) recalculation, T) thermodynamical calculation, X) original paper not available, C) citation, Q) QSPR, E) estimate, ?) unknown, W) wrong. See Section 3.1 of Sander (2015) for further details.


7) Several references are given in the list of Henry's law constants but not assigned to specific species.
19) Value at T = 310 K.
23) Value at T = 303 K.
31) Value at T = 295 K.
89) Measured at high temperature and extrapolated to T = 298.15 K.
100) Calculated from the solvation enthalpy, using the van 't Hoff equation.
103) The value is most probably taken from the report by Howe et al. (1987).
116) Value given here as quoted by Staudinger and Roberts (1996).
123) It was found that H changes with the concentration of the solution.
130) Values for salt solutions are also available from this reference.
188) Data from Table 1 by Zhou and Mopper (1990) were used to redo the regression analysis. The data for acetone in their Table 2 are incorrect.
196) Calculated under the assumption that ∆G and ∆H are based on [mol/l] and [atm] as the standard states.
