New experimental excess molar enthalpy data (420 points) of the ternary systems dibutyl ether (DBE) and 1-butanol and 1-hexene at 298.15 K and 313.15 K, and DBE and 1-butanol and cyclohexane or 2,2,4-trimethylpentane (TMP) at 313.15 K at atmospheric pressure are reported. A quasi-isothermal flow calorimeter has been used to make the measurements. All the ternary systems show endothermic character. The experimental data for the ternary systems have been fitted using the Redlich–Kister rational equation. Considerations with respect the intermolecular interactions amongst ether, alcohol and hydrocarbon compounds are presented.
► New excess enthalpy data for ternary mixtures of dibutyl ether + hydrocarbon + 1-butanol are reported.
► Four ternary systems at 298.15 K and 313.15 K were measured by means of an isothermal flow calorimeter.
► 420 Data were fitted to a Redlich–Kister rational equation.
► Intermolecular and association effects involved in these systems have been discussed.
