Previous papers have reported equilibrium data for the binary systems cyclohexaneheptane, heptane‐toluene, and cyclohexane‐toluene. This present study gives similar data for the ternary system cyclohexane‐heptane‐toluene and compares the activity coefficients with those predicted from the three limiting binaries. The ternary activity coefficients fall well in line between the limiting‐binary data. Distribution is about as would be predicted by the ternary Margules equations. As an approximation, if the coefficients are plotted as a function of the aromatic concentration only, without consideration of the ratio of naphthenes to paraffins, reasonably good correlation is observed.
