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

452)	Leriche et al. (2000) assume H_s(ROO) = H_s(ROOH) ×H_s(HO₂) / H_s(H₂O₂).
453)	Lelieveld and Crutzen (1991) assume H_s(CH₃OO) = H_s(HO₂).
454)	Jacob (1986) assumes H_s(CH₃OO) = H_s(CH₃OOH) ×H_s(HO₂) / H_s(H₂O₂).

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