abstract
Comprehensive isochoric (p, Vm, x, T) values have been obtained for {xCH4 + (1 - x)C2H6} with x = 0.35, 0.50, and 0.69 at amount-of-substance densities from 1 to 25 moldm-3. The measurements for each composition cover a temperature range from approximately 100 to 320 K at pressures up to 35 MPa. For each mixture the results have been fit to a 32-term modified Benedict-Webb-Rubin equation of state. Further development of the extended corresponding-states model has been accomplished using the results presented here. Comparisons with values from independent sources have been made where possible. 1985.
