- •
Solution enthalpies of 18 branching-chain alkyl aromatic and aliphatic compounds in cyclohexane were measured.
- •
Group contributions to the enthalpy of solvation due to branching and substitution in carbon chain were evaluated.
- •
Modified solution calorimetry based approach for determination of vaporization/sublimation enthalpies was proposed.
- •
This approach provides vaporization/sublimation enthalpies directly at T = 298.15 K.
- •
Vaporization/sublimation enthalpies of 35 branched-chain alkyl aromatic and aliphatic compounds were determined.
