This critical compilation of virial coefficients of mixtures is a sequel to The Virial Coefficients of Pure Gases and Mixtures, by J.H. Dymonand E.B. Smith (Oxford Universi Press, 1979) and a companion of Virial Coefficients of Gases and Gas Mixtures, Subvolume A, Pure Compounds. This new and enlarged edition was prepared from the virial coefficient database at the Thermodynamics Research Center created a subset of the TRC SOURCE data system. This compilation will be of interest to the theoretical chemist as it includes the many sets of accurate gas imperfection data on mixtures which have been determined over the past twenty years by improved methods of gas density determination, by isochoric Burnett coupling methods and from speed of sound measurements, as well as by the more traditional techniques. The needs of the industrial chemist are met by these more reliable data and also the increased number of mixtures for which data are now available.For each mixture, the second virial coefficient data from different published sources are tabulated in increasing order of temperature, and an estimate of the uncertainty is given. conversion to a uniform set of units is undertaken where necessary. In the majority of cases, where the data cover a sufficiently wide range of temperature, a weighted data fit has been made for the interaction second virial coefficients, ancoefficients of the given equation are recorded. Values of the interaction second virial coefficient given by the equation at selected temperatures are quoted.
