Abstract
The solubility of carbon tetrachloride in compressed helium, hydrogen, nitrogen, argon, methane, carbon dioxide, and ethylene has been measured over pressure ranges of 1–60 atm at temperatures ranging from −10 to 75 °C. Second cross virial coefficients representing carbon tetrachloride – gas interactions are evaluated from the data. It is shown that when allowance is made for the effects of quantum deviations and quadrupolar interaction on the critical temperatures and volumes of helium, hydrogen, and carbon dioxide, respectively, ordinary combining rules produce pseudocritical parameters which reduce all of the measured cross virial coefficients to a single function of reduced temperature. When reduced on a Boyle point basis, it is found that the data are best represented by virial coefficients corresponding to a 7-28 Mie type potential or a Kihara core potential having a core radius somewhat smaller than the carbon–chlorine bond length in carbon tetrachloride.
