The interaction second virial coefficients, <I>B</I><SUB>12</SUB>, and <I>PVTx</I> behavior for the binary systems consisting of N<SUB>2</SUB>, CO<SUB>2</SUB>, CH<SUB>4</SUB>, C<SUB>2</SUB>H<SUB>6</SUB>, C<SUB>3</SUB>H<SUB>8</SUB>, and normal C<SUB>4</SUB>H<SUB>10</SUB> are estimated by means of the Deiters equation of state (EoS). In this way a new combining rule based on the modified Lorentz–Berthelot combining rule is proposed for this EoS. The binary interaction parameters for these combining rules are calculated by fitting the expression for the interaction second virial coefficient derived from the Deiters EoS to the experimental cross virial coefficient data. The calculated <I>B</I><SUB>12</SUB> values from the optimized binary interaction parameters and Deiters EoS are in good agreement with experimental data. Also a van der Waals type mixing rule with the two binary interaction parameters <I>k<SUB>ij</SUB></I> and <I>l<SUB>ij</SUB></I> obtained from the experimental <I>B</I><SUB>12</SUB> values is presented for the Deiters equation of state, which is able to predict the volumetric properties of the above mixtures to a good degree of accuracy in the specified temperature and pressure range. Also it has been shown that the Deiters EoS has higher accuracy relative to the Peng–Robinson EoS for the prediction of the volumetric properties of the mixtures studied in this work.
