Experimental and theoretical study on excess molar enthalpy of binary mixtures containing isobutanol (1)Â +Â alkan-1-ols (C1-C4) (2) at TÂ =Â 298.15Â K

Excess molar enthalpy was correlated by using the Redlich-Kister and SSF equations and also used to test the applicability of the Wilson, NRTL and UNIQUAC models. Comparison between experimental and theoretical results is represented graphically for Isobutanol + methanol.
