Measurement of the temperature variation of virial coefficients. III. The second virial coefficient of Carbon Disulphide, Methyl Chloride, Acetone, and Methanol, and certain of their binary mixtures

Abstract

Second virial coefficients have been determined for carbon disulphide, methyl chloride, acetone, and methanol over the temperature range of 50-150° with some additional results at lower temperatures. Similar work has been conducted on the selected mixtures methyl chloride-carbon disulphide, methyl chloride-acetone, acetone-carbon disulphide, and methyl chloride-argon. Methanol, exceptionally, shows very significant third virial contributions in the sub-atmospheric pressure range. A comparison is made with recent models pertaining to molecular interactions between unlike molecules possessing dipolar and quadrupolar contributions to the intermolecular forces.
