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

201) The value given here was measured at a liquid phase mixing ratio of 1 μmol/mol. Servant et al. (1991) found that the Henry's law constant changes at higher concentrations.
202) Abraham (1984) smoothed the values from a plot of enthalpy against carbon number.
