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

81)	Value at T = 288 K.
239)	Calculated using linear free energy relationships (LFERs).
240)	Calculated using SPARC Performs Automated Reasoning in Chemistry (SPARC).
241)	Calculated using COSMOtherm.
439)	Henry's law constants calculated using the GROMHE model. Temperature dependences calculated with the method of Kühne et al. (2005).
