Influence of the composition of water-organic mixtures and the properties of organic solvents on thermochemical characteristics of l-methionine dissolution at 298.15Â K

- Enthalpies of l-methionine dissolution were measured in eight aqueous-organic mixtures.
- Solvation of l-methionine depends on the physicochemical properties of an organic solvent.
- Increase in polarity, acidity of solvent strengthens its interactions with l-methionine.
- Increase in volume, basicity of co-solvent weakens its interactions with l-methionine.
