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.

Notes

222)

Calculated using ∆G_s^{g→ H₂O} and ∆H_s^{g→ H₂O} from Table IV of Arnett and Chawla (1979). Since some of the values in this table are taken directly from Andon et al. (1954), it is assumed that the thermodynamic properties are defined in the same way. Since ∆H_s^{g→ H₂O} is defined relative to pyridine, a value of -11.93 kcal/mol from Arnett et al. (1977) was added.

The numbers of the notes are the same as in Sander (2015). References cited in the notes can be found here.
