EnglishSome results are reported concerning the enthalpies of solvation (Delta H-solv(o)) of some hydrocarbons (hexane, cyclohexane), ethers (tetrahydrofuran), ketones (cyclopentanone, pentan-3-one), alcohols (butan-1-ol. butan-2-ol). and water in octan-2-ol and hexylacetate. The Delta H-solv(o) values were calculated by combining the calorimetric heats of solution here determined with the known enthalpies of vaporisation. In the investigated solvents, the enthalpies of solvation become less negative going from alcohols to ketones to ethers and to hydrocarbons. As regards alcohols and ketones, the Delta H-solv(o) values are more differentiated in octan-2-ol than in hexylacetate. This reflects the different nature of the two solvents, amphiprotic the former and hydrogen bond acceptor the latter. The results are interpreted in terms of specific solute-solvent interactions.
