Abstract Ternary vapor compositions have been successfully calculated from total‐pressure measurements for four systems by means of a modified direct method, which involves the previously proposed concept of hypothetical binary mixtures, and permits the numerical integration using a simple P‐x relationship. The results of the systems tested further indicate that the ternary y values predicted from only binary P‐x data are not significantly different from the y values obtained when binary together with ternary P‐x values were used in the calculation, provided that the initial fit of binary P‐x data is successful.
