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 (2023) for further details.

Notes

187) Estimation based on the quotient between vapor pressure and water solubility, extracted from HENRYWIN.
375) Value at T = 283 K.
537) Based on gas chromatograph retention indices (GC-RIs).
