THE DENSITY OF GASEOUS ETHANE AND OF FLUID METHYL-CHLORIDE, AND THE VAPOR-PRESSURE OF METHYL-CHLORIDE Academic Article uri icon

abstract

  • The amount-of-substance density {variant}n of gaseous ethane was measured in a Burnett-isochoric apparatus from 323 to 473 K in 25 K increments. Thirteen isochores ranging from 15.94 to 1489.0 mol m-3 nominal {variant}n provide pressures from 43.0 to 5390kPa. For methyl chloride values of {variant}n were observed at the same temperatures covering the vapor, gas, and near-critical regions. Seventeen isochores ranging from 20.42 to 8653.1 mol m-3 nominal {variant}n provide pressures from 55.4 to 14908 kPa. Dense-vapor values near saturation are corrected for adsorption by a new technique. Second and third virial coefficients as well as derived thermophysical properties are reported for both ethane and methyl chloride. Optimal Lennard-Jones and Stockmayer force constants are calculated for ethane and methyl chloride respectively. Two sets of vapor pressures for methyl chloride are reported for the temperature range 313 to 408 K (T68c = 416.27 K). 1981.
