ABSTRACT

Densities for binary mixtures 1,2-dibromoethane + heptane have been measured within the temperature range from 293 K to 313 K using a vibrating-tube densimeter. The phase speeds of ultrasound have been measured with a pulse-echo-overlap apparatus. The heat capacities at constant pressure have been measured with a differential scanning calorimeter DSC III (Setaram). From those experimental data, the excess molar volumes, excess isobaric molar heat capacities, excess isochoric molar heat capacities, excess molar isobaric expansions, excess molar isentropic compressions, excess molar isothermal compressions, excess ultrasonic speeds, and excess internal pressures have been calculated.
