Further information:

Participation in the e-learning course is recommended. All downloads and further information are provided in the OLAT course. Exercise problems are provided there, and their solutions can be discussed in the forums set up for this purpose. You will also receive further information and tips this way. The course code will be announced in the lecture.

Contents:

• Fundamentals: partial molar properties, fundamental equation, Legendre transformation, Helmholtz energy, Gibbs energy
• Thermal and caloric properties of mixtures: excess volume, excess enthalpy, thermal equations of state
• Phase equilibria (phenomenology): phase diagrams, two-phase and multiphase equilibria, azeotropy, heteroazeotropy, high-pressure phase equilibria
• Phase equilibria (modeling and calculation): fugacity, fugacity coefficient, activity, activity coefficient, Gᴱ models, vapor–liquid equilibrium (Raoult’s law), gas solubility (Henry’s law), liquid–liquid, solid–liquid, high-pressure, and membrane equilibria
