Brief content Using the equipment of the Center of Thermal Analysis and Calorimetry of Saint Petersburg State University, we experimentally investigated the dependences of the excess molar enthalpies of binary solutions on the composition for biazeotropic systems acetic acid - isobutyl acetate, butyl propionate - propionic acid, butyl butyrate - butyric acid at 373.15 K and atmospheric pressure. Using these data, the integral and differential enthalpies of evaporation were calculated for the specified biazeotropic systems over the entire concentration range.
