Abstract—The critical (liquid–vapor) temperatures were determined by the ampule method for 10 binary mix-
tures 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.
