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

31) Value at T = 295 K.
192) Effective value that takes into account the hydration of the aldehyde:
H= ([RCHO]+[RCH(OH)2])/p(RCHO)
