Abstract

This paper presents volumetric data for the mixtures xenon-ethane, xenon-ethene and xenon-carbon dioxide, with xenon mole fractions covering the whole composition range, at 273.00 K and pressures up to 3.5 MPa, measured using a Burnett apparatus. Second and third virial coefficients were derived for each mixture from the experimental compressibility factors, Z. Data for the pure components are also determined for consistency purposes and for the calculation of the unlike-interaction virial coefficients, B 12 , C 112 and C 122 . Corrections for the effects of adsorption, and the procedure for computation of the compressibility factors and virial coefficients are described. In order to accomplish a better understanding of the intermolecular forces present in real fluids, the cross virial coefficients, B 12 , of the studied systems were theoretically calculated using a two centre Lennard-Jones (L-J) model, and compared with experimental data. The importance of the third virial cross coefficients C 112 and C 122 is discussed.
