| 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. |
