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

36) This value was extrapolated from data at T = 230 K and T = 273 K.
37) Fast, irreversible hydrolysis is assumed, which is equivalent to an infinite effective Henry's law constant.
