Phase Behavior Studies of Ternary Systems

A ternary phase diagram shows if a system composed of three components is forming a single phase, two phases, or more than two phases, depending on composition. We adapted a laboratory experiment measuring a ternary phase to utilize Nuclear Magnetic Resonance (NMR) spectroscopy for obtaining composition information. Details will be shown regarding typical systematic errors and how to prevent them. We then used our know-how to measure unknown ternary phase diagrams involving ionic liquids as one of the components. Ionic liquids are salts, liquid at room temperature, currently explored as "green" solvents for chemical processes. Preliminary ternary phase diagram results will be presented.
