The critical temperatures of some ternary siloxane mixtures are reported. The critical temperatures of binary perfluoromethylcyclohexane and siloxane mixtures were also measured. The results are compared to values calculated by solving the critical conditions from conformal solution theory using the

β¦ Synopsis
The critical temperatures of several ternary mixtures containing hydrocarbons, acetone, acetonitrile and propylcyanide are reported. A Newton-Raphson procedure and a general solution for solving the criticality conditions of ternary mixtures using the one-fluid model and the Guggenhiem equation of state are outlined. The critical temperatures of the three related binary mixtures were used to obtain the three unlike interaction parameters so that no additional parameters were needed to calculate the critical temperatures of the ternary mixtures. Agreement between experiment and theory is, in general, quite good.
