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.


9) Value at T = 293 K.
31) Value at T = 295 K.
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.
116) Value given here as quoted by Staudinger and Roberts (1996).
145) Value given here as quoted by Petrasek et al. (1983).
221) Mackay et al. (2006d) list a vapor pressure p, a solubility c, and a Henry's law constant calculated as p/c. However, the data are internally inconsistent and deviate by more than 10 %.
