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.


92) Yaws and Yang (1992) give several references for the Henry's law constants but don't assign them to specific species.
129) Calculated using Gh and Hh from Table 2 in Andon et al. (1954). Note that the thermodynamic functions in that table are not based on their α in Table 1. Instead, the expression exp(−Gh/(RT)) yields the Henry's law constant Hsxp in the unit 1/atm.
222) Calculated using ∆Gsg→ H2O and ∆Hsg→ H2O from Table IV of Arnett and Chawla (1979). Since some of the values in this table are taken directly from Andon et al. (1954), it is assumed that the thermodynamic properties are defined in the same way. Since ∆Hsg→ H2O is defined relative to pyridine, a value of -11.93 kcal/mol from Arnett et al. (1977) was added.
223) Due to an apparently incorrect definition of the Henry's law constant by Andon et al. (1954), Staudinger and Roberts (2001) quote incorrect values from that paper.
