Send email with questions, corrections, or suggestions to LearnChemE@gmail.com Motivation:
The phase diagrams for immiscible liquids helps understand solid-liquid phase diagrams that have multiple solid phases.
This module is intended for a Thermodynamics course and may also be useful for a Materials course. Pre-requisites:
After studying this module, you should be able to:

Overview
This
module uses screencasts and interactive simulations to explain the vapor-liquid
phase equilibrium of two immiscible liquids.
Screencast A Txy diagram is used to explain phases present for vapor-liquid-liquid equilibrium for two immiscible species. Important Equations
Interactive Simulations
These simulations were prepared using Mathematica.
To use them, download the free CDF player available here, download the simulation CDF file (click on the images below). Then, try to predict the behavior when some parameter changes before using a slider to change the parameter. For most simulations, a screencast is provided to explain how to use the simulation. Immiscible Liquids on Pressure-Composition Diagram This simulation shows
a pressure-composition phase diagram for two immiscible liquids, benzene and water.

Temperature-Composition Diagrams for Immiscible Liquids This simulation shows a temperature-composition phase diagram for two immiscible liquids, benzene and water. The pressure and overall mole composition can be changed with sliders. The bar graph shows the moles of liquid water (blue), liquid benzene (orange), and vapor (green). The system contains one mole total.
