Data

The first column contains Henry's law solubility constant

H_{s}^{cp}

at the reference temperature of 298.15 K.
The second column contains the temperature dependence

d ln H_{s}^{cp} / d
(1/ T)

, also at the reference temperature.

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 (2015) for further details.

Notes

38)	Calculated based on the method by Meylan and Howard (1991).
158)	Value obtained by Saxena and Hildemann (1996) using the group contribution method.
196)	Calculated under the assumption that ∆G and ∆H are based on [mol/l] and [atm] as the standard states.

The numbers of the notes are the same as in Sander (2015). References cited in the notes can be found here.
