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

153) Value given here as quoted by Gaffney et al. (1987).
158) Value obtained by Saxena and Hildemann (1996) using the group contribution method.
205) Value at pH = 4.
