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

1)	A detailed temperature dependence with more than one parameter is available in the original publication. Here, only the temperature dependence at 298.15 K according to the van 't Hoff equation is presented.
20)	Calculated using machine learning matrix completion methods (MCMs).
187)	Estimation based on the quotient between vapor pressure and water solubility, extracted from HENRYWIN.
769)	The data from Maaßen (1995) were fitted to the three-parameter equation: H_s^cp= exp( −155.04312 +9704.04801/T +20.06575 ln(T)) mol m⁻³ Pa⁻¹, with T in K.
