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 (2015) for further details.

Notes

19) Value at T = 310 K.
92) Yaws and Yang (1992) give several references for the Henry's law constants but don't assign them to specific species.
107) Data taken from the supplement.
108) Calculated using the EPI Suite (v4.0) method.
109) Calculated using the SPARC (v4.2) method.
110) Calculated using the COSMOtherm (v2.1) method.
111) Calculated using the ABSOLV (ADMEBoxes v4.1) method.
