Type

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 (2023) for further details.

Notes

1) A detailed temperature dependence with more than one parameter is available in the original publication. Here, only the temperature dependence at 298.15 K according to the van 't Hoff equation is presented.
20) Calculated using machine learning matrix completion methods (MCMs).
21) Several references are given in the list of Henry's law constants but not assigned to specific species.
23) The partial pressure of water vapor (needed to convert some Henry's law constants) was calculated using the formula given by Buck (1981). The quantities A and α from Dean and Lange (1999) were assumed to be identical.
210) The data from Lewis et al. (1987) were fitted to the three-parameter equation: Hscp= exp( 5.03587 +1555.37916/T −3.42648 ln(T)) mol m−3 Pa−1, with T in K.
211) Calculated employing molecular force field models for the solutes from Mick et al. (2016).
212) The data from Dean and Lange (1999) were fitted to the three-parameter equation: Hscp= exp( −240.66156 +12686.97685/T +33.12171 ln(T)) mol m−3 Pa−1, with T in K.
