I am by no means trying to put down anyone or any software, but from my experience with COSMO/COSMO-RS to find various properties, including solubility, most of the time, not only the quantitative values, even the qualitative trend predicted by the software/model is against experimental data. This was known for aqueous mixtures of methanol, ethanol, propanol, acetone, DMF, etc. The reasoning given is typically as simple as: If you put X mole of salt in Y mL of water, all of the salt will dissolve, but if you put X mole of salt in Y mL of oil, the salt will remain undissolved.

It's not very clear other than running the solubility experiments in these solvents and their mixtures with water, which defeat the purpose of having a theory to explain the observation in the first place. Karla Isabel Rivera-Márquez, Carolina Godoy-Alcántar, Miguel Ángel Claudio-Catalán, Felipe Medrano. With regard to the relationship between conductivity-solubility-ionic dissociation, I agree.
