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

14)	Value at T = 310 K.
21)	Several references are given in the list of Henry's law constants but not assigned to specific species.
42)	Fitting the temperature dependence dlnH/d(1/T) produced a very low correlation coefficient (r² < 0.5). The data should be treated with caution.
68)	Modarresi et al. (2007) use different descriptors for their calculations. They conclude that a genetic algorithm/radial basis function network (GA/RBFN) is the best QSPR model. Only these results are shown here.
81)	Value at T = 288 K.
185)	Value from the validation set for checking whether the model is satisfactory for compounds that are absent from the training set.
186)	Experimental value, extracted from HENRYWIN.
239)	Calculated using linear free energy relationships (LFERs).
240)	Calculated using SPARC Performs Automated Reasoning in Chemistry (SPARC).
241)	Calculated using COSMOtherm.
243)	Value from the training dataset.
244)	Calculated using the GROMHE model.
245)	Calculated using the SPARC approach.
246)	Calculated using the HENRYWIN method.
279)	Data are taken from the report by Howe et al. (1987).
541)	Temperature dependencies in Tables 1 and 2 of Ashworth et al. (1988) are inconsistent, with 31 % difference.
