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

644)	The data from Clever et al. (2005) were fitted to the three-parameter equation: H_s^cp= exp( 289.52696 −11352.27202/T −46.16631 ln(T)) mol m⁻³ Pa⁻¹, with T in K.
645)	The Ostwald coefficient given by Clever et al. (2005) at 313.2 K is probably incorrect. Therefore, the Ostwald coefficients are not used. Instead, H_s is calculated using the amount fraction x₁ from the same table.

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