ABSTRACT
New experimental excess molar enthalpy data (304 points) of the binary systems dibutyl ether (DBE) or 1-butanol and 1-hexene, or methylcyclohexane or toluene at 298.15K and 313.15 K, and DBE or 1-butanol and cyclohexane or 2,2,4-trimethylpentane (TMP) at 313.15K at atmospheric pressure are reported. A quasi-isothermal flow calorimeter has been used to make the measurements. All the binary systems show endothermic character except the system DBE + 1-hexene at both temperatures. The experimental data for the binary systems have been fitted using the Redlich-Kister rational equation. The values of the standard deviation indicate good agreement between the experimental results and those calculated from the equations.
