Heat of mixing of binary mixtures consist of butylacetate (۱) + ۱-alkanols (C۱–C۳)(۲) at ۲۹۸.۱۵ K and ambient pressure

Heat of mixing data is extensively used to test and improves theories of mixtures and provides thermodynamic data for the development and design of chemical engineering processes. In this paper heat of mixing, for binary systems of butylacetate + methanol, ethanol and ۱-propanol at ۲۹۸.۱۵ K and atmospheric pressure were measured experimentally. The experimental results were correlated with a polynomial with Redlich–Kister equation [۱] 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 Wilson model [۲].
