Data

The first column contains Henry's law solubility constant

H_{s}^{cp}

at the reference temperature of 298.15 K.
The second column contains the temperature dependence

d ln H_{s}^{cp} / d
(1/ T)

, also at the reference temperature.

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

403)	Value obtained by Saxena and Hildemann (1996) using the group contribution method.
445)	Compernolle and Müller (2014b) recommend H_s^cp for 1,7-heptanediol in the range of 4.5×10⁴ mol m⁻³ Pa⁻¹ < H_s^cp < 8.3×10⁴ mol m⁻³ Pa⁻¹.
