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 (2023) for further details.

Notes

821)	Calculated using HENRYWIN 3.21.
822)	Calculated using vapor pressures and water solubilities from HENRYWIN 3.21.
823)	Calculated using vapor pressures and water solubilities from the EPA Toxicity Estimation Software Tool (TEST).

The numbers of the notes are the same as in Sander (2023). References cited in the notes can be found here.
