Abstract:  A simple method for calculating the activity coefficients of components in liquid phase and vapour composition of ternary systems is presented. The calculation is based on the data of vapour pressure of liquid solutions of known composition measured along the lines of constant ratio of the molar fractions of both components. The equations of the Tao method modified for inconstant integration step Ax are applied. By means of the equations thus modified it is possible to calculate the equilibrium data immediately for individual experimental points.
