New experimental excess molar enthalpy data of the ternary systems (dibutyl ether+ 1-propanol + cyclohexane), or methylcyclohexane, and the corresponding binary systems at T= (298.15 and 313.15) K at atmospheric pressure are reported. A quasi-isothermal flow calorimeter has been used to make the measurements. All the binary and ternary systems show endothermic character at both temperatures. The experimental data for the systems have been fitted using the Redlich-Kister rational equation and the UNIQUAC model. (C) 2016 Elsevier Ltd.
