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

20)	Calculated using machine learning matrix completion methods (MCMs).
45)	Young (1981a) recommend the data from Muccitelli and Wen (1978).
46)	The data from Muccitelli and Wen (1978) were fitted to the three-parameter equation: H_s^cp= exp( −103.11330 +4676.56978/T +13.28348 ln(T)) mol m⁻³ Pa⁻¹, with T in K.
