Abstract : A simple method is presented for the accurate calculation of the crossterm B(12) of binary mixture second virial coefficients. For evaluation the second virial coefficients of the components and the relation T(BM)(x) between the Boyle-temperatures and the concentration x of the examined mixture are required. The determination of this characteristic function limiting the validity range of the new method, is described. Finally, the crossterm B(12) is evaluated for 3 mixtures for which accurate experimental values are available. The agreement between measured and calculated properties is good.
