Thermodynamic and acoustic properties of binary mixtures of alcohols and alkanes. II. Density and heat capacity of (ethanol + n-heptane) under elevated pressures
The density of (ethanol + n-heptane) was measured in the whole composition range under atmospheric pressure and at temperatures from (293 to 318) K using a vibrating tube densimeter. The densities and heat capacities at pressures up to 90 MPa and for temperatures ranging from (293 to 318) K for (ethanol + n-heptane) mixtures were calculated using the speeds of sound under elevated pressures, reported in part I of this study, together with the densities and heat capacities at atmospheric pressure. The effect of pressure and temperature on the adiabatic compressibility, the excess molar volume and the excess molar heat capacity has been discussed.
