The NRTL and UNIQUAC equations are used to correlate the experimental data and to predict the phase compositions of the ternary systems. Animated PDF: The system Di-An-Ab at 1 atm. pressure. This animation is based on Figure in An Introduction to Igneous and Metamorphic Petrology (Winter ).

Melt compositions have been estimated based on the binary (Ab-An) system and the (ternary) cotectic compositions. See discussion in Winter's book for more explanation. (Liquid + Liquid) Equilibrium for Ternary System of (Water + Phenol + Cyclohexane) at T = K: /ijcce Experimental solubility curves and tie-line data for the (water + phenol + 2-ethylhexanol) system was obtained at T = K and atmospheric pressure.

The. The ternary system. The experimental literature information on the ternary In–Ni–Sn system is partially summarized in.A phase diagram study at °C was published by Bhargava and Schubert, who established a partial isothermal section in the Ni-rich part, whereas the (In,Sn)-rich area was investigated using samples that had been furnace-cooled to room temperature.

Consider a ternary mixture of water, ethyl acetate, and acetone. This Demonstration displays the liquid-liquid equilibrium diagram, which is classified as type I, meaning that the diagram contains a single plait point, for user-set values of the temperature.

Some green tie lines are shown. The plait point is calculated and shown by the red dot. If the components of a system were Cl2, Br2, and I2, how could I describe this system under equilibrium conditions when the number of phases is at a maximum. If there are 3 components, using the formula, F=M+2-P and solving for P under equilibrium conditions there would be a total of 5 phases.

Triangular diagrams are advantageous for the graphical presentation of phase equilibria of liquid ternary systems at a constant temperature and pressure. We will use equilateral triangles due to the clear shape. Rectangular triangles are often used in literature (e.g.[5]), which does not change the coherence.

Results and Discussion.
