This report contains experimental P-V-T values for CO2 + C2H6 mixtures. For each mixture, a Burnett
apparatus was used to measure densities at 300 and 320 K at pressures to 7 MPa. A continuously
weighed, high pressure pycnometer was used to measure densities at temperatures from 240 to 350 K
and pressures to 35 MPa. An isochoric apparatus was used to measured densities and phase boundary
conditions between 235 and 400 K at pressuress to 12 MPa. A flow calorimeter was used to measure
enthalpy differences at temperatures from 230 to 350 K at pressures between 15 and 19 MPa. The
densities are accurate to better than 0.1 %, and a detailed error analysis is given. Second, third and cross
viria1 coefficients, energies and entropies were derived from P- V- T measurements. The derived
enthalpies are of approximately the same accuracy (within a factor of two) as those obtained from
calorimetric measurements. This report contains approximately 700 measured values and approximately
1500 derived values.
