Concentration dependences of the critical temperatures of binary mixtures of nonaqueous components

The critical (liquid-vapor) temperatures were determined by the ampule method for 10 binary mixtures containing aliphatic alcohols, n-octane, n-decane, methyl ethyl ketone, benzene, and toluene in various combinations. The predictive potential of several calculation methods was considered. The methods using binary interaction parameters as functions of the ratio between the critical volumes of compounds were found to correctly describe experimental data.
