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.
227) Comparing the value with that from the cited publication (Kames and Schurath 1995), it can be seen that the unit and the temperature listed in Table 3 of Warneck et al. (1996) are incorrect.
229) The data from Kames and Schurath (1995) for peroxypropionyl nitrate are incorrectly cited by Schurath et al. (1996).

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