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.


3) Value given here as quoted by Fogg and Sangster (2003).
5) Value given here as quoted by Lide and Frederikse (1995).
24) The parametrization given by Lide and Frederikse (1995) with parameters A, B, and C doesn't fit the data in the same paper for this substance. Therefore the parametrization of the solubility data was recalculated.

The numbers of the notes are the same as in Sander (2015). References cited in the notes can be found here.
