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.


3) Value given here as quoted by Fogg and Sangster (2003).
5) Value given here as quoted by Lide and Frederikse (1995).
6) Only the tabulated data between T = 273 K and T = 303 K from Dean (1992) were used to derive Hs and its temperature dependence. Above T = 303 K, the tabulated data could not be parameterized very well. The partial pressure of water vapor (needed to convert some Henry's law constants) was calculated using the formula given by Sander et al. (1995). The quantities A and α from Dean (1992) were assumed to be identical.
7) Several references are given in the list of Henry's law constants but not assigned to specific species.
25) The H298 and A,B,C data listed in Table 5.4 of Sander et al. (2011) are inconsistent, with 94 % difference.
26) The H298 and A,B,C data listed in Table 5.4 of Sander et al. (2006) are inconsistent, with 94 % difference.
27) Value at T = 297 K.
28) Value at T = 288 K.
29) Erratum for page 269 of Fogg and Sangster (2003): The equation is incorrect and not consistent with the corresponding equation for ln(x): The temperature in the last term must be divided by 100 (i.e. ln(T/100) not ln(T)) and an additional term of ln(100) must be added.
30) The fitting parameters A, B, C, and D in Table I of Wilhelm et al. (1977) do not reproduce the data in their Table III.
