Summary: water/cyclohexane partition database
The original question:
> We need data on solvation free energies for as many organic compounds as
> possible, especially for non-polar solvent.
> Does anyone know of such a database (preferably, on-line, preferably,
> free)?
======================================================================
I know of ACD labs database and prediction tool for octanol/water
partition coefficient (and its pH dependence for charged structures)
http://www.acdlabs.com/products/phys_chem_lab/compare.html
Unfortunately, you have to buy it or pay monthly fee for Internet access.

The replies I got:
From: "Eldbjørg Sofie Heimstad" <Eldbjorg.Sofie.Heimstad $#at#$
nilu.no>
Rolf Claessen's Chemistry Index:

&
http://www-fbsc.ncifcrf.gov/compenv/app_soft/index.html
(for instance AMSOL software)
From: "Dave" <giesen $#at#$ chem.umn.edu>
You'll find a considerable amount of data at:
http://comp.chem.umn.edu/amsol/AlkaneSuppTables.html
which is supplementary material for a paper published in J. Phys. Chem.
Journal of Physical Chemistry, 99, 7137-7146 (1995)
From: Kristy Mardis <mardis $#at#$ carb.nist.gov>
You might want to look at:
D. J. Giesen, C. J. Cramer, and D. G. Truhlar
J. Phys. Chem vol 99, p. 7137, 1995
They provide tables (in supplemental material) of a number of
experimental solvation free energies in nonpolar solvents.
From: Flemming Steen Jorgensen <flemming $#at#$ medchem.dfh.dk>
The following reference contains a lot of free energy of solvation data:
S. Cabani, P. Gianni, V. Mollica and L. Lepori,
Group contributions to the thermodynamic properties of non-ionic
organic solutes in dilute aqueous solution,
Journal of Solution Chemistry, 1981, vol. 10, number 8, pp. 563-595.
