Excess and Interaction Second Virial Coefficients for Ten Binary Gaseous Systems Containing SF6

Excess and interaction second virial coefficients have been measured over the temperature range 290 – 320 K for binary systems of SF6 with He, Ne, Ar, Kr, Xe, N2, O2, CO2, CH4, and CF4. The excess virial coefficients are estimated to have an accuracy of 0.2 cm3 mol−1 and have been used to calculate molar excess enthalpies for each system at 300 K.
