چكيده فارسي :
Excess molar enthalpy data are extensively used to test and improves theories of mixtures and provide thermodynamic data for the development and design of chemical engineering processes. In this paper excess molar enthalpies, for binary systems of butylacetate + methanol, ethanol and 1-propanol at 298.15 K and atmospheric pressure were measured experimentally. The experimental results were correlated with a polynomial with Redlich–Kister equation for binary mixtures to estimate the coefficients. The binary excess molar enthalpies for all systems under investigation are found to be positive over the entire range of compositions. The experimental results were explained according to the NRTL model.
