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.

Notes

20)	Calculated using machine learning matrix completion methods (MCMs).
187)	Estimation based on the quotient between vapor pressure and water solubility, extracted from HENRYWIN.
765)	The data from Maaßen (1995) were fitted to the three-parameter equation: H_s^cp= exp( −277.88370 +14905.51805/T +38.38688 ln(T)) mol m⁻³ Pa⁻¹, with T in K.
766)	The data from Reichl (1995) were fitted to the three-parameter equation: H_s^cp= exp( −195.56650 +11207.08869/T +26.12575 ln(T)) mol m⁻³ Pa⁻¹, with T in K.
