Abstract
The densities of propan-1-ol + n-heptane have been measured over the whole composition range at atmospheric pressure and at temperatures from 293 to 318 K using a vibrating tube densimeter. The densities and heat capacities for propan-1-ol + n-heptane mixtures at pressures up to 120 MPa and for temperatures ranging from 293 to 318 K were calculated using the speeds of sound measured under elevated pressures, together with the densities and heat capacities at atmospheric pressure. A modified method, based on the suggestion of Davis and Gordon “J. Chem. Phys. 46 (1967)”, has been applied. The effect of pressure and temperature on the isentropic compressibility, the excess volume, and the excess heat capacity are discussed.
