The excess molar enthalpies H", of (xN20+(1-x)C,H,,) were measured in the liquid and supexcritical region covering the whole concentration range. Mixtures at 308.15 K and 7.64, 9.48 and 12.27 MPa show moderately endothermic and exothermic mixing in the heptane-rich region and nitrous oxide-rich region, respectively. The exothermic-mixing region is confiied to a smaller range of x as pressure increases and disappears completely at 308.15 K and 15.00 MPa. Mixtures at 318.15 K and 7.64 and 9.48 MPa show very exothermic mixing. Mixtures at 318.15 K and 12.27 and 15.00 MPa show moderately endothermic and exothermic mixing in the heptane-rich region and nitrous oxide-rich region, respectively. The changes observed in the excess enthalpy with temperature and pressure are discussed in terms of liquid-vapor equilibrium and critical constants for nitrous oxide-heptane. Excess enthalpies for nitrous oxide-heptane mixtures are also calculated by means of the Peng-Robinson equation of state and the resulting H", values are compared with experiment.

“…The density of the methanol was calculated at each temperature and pressure from an equation of state. (5) The densities (6) of heptane, methylcyclohexane, and toluene were determined from the values at T = 298.15 K and p = 0.101 MPa, and the isothermal compressibilities (7)(8)(9) …”
