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

42)	Fitting the temperature dependence dlnH/d(1/T) produced a very low correlation coefficient (r² < 0.5). The data should be treated with caution.
288)	Data taken from the supplement.
721)	Modified gas-stripping method (MGSM); see Lau et al. (2006) for details.
722)	Integrated gas-stripping method (IGSM); see Lau et al. (2006) for details.
