Research Interests
The general focus of the Brennecke Research Group is the utilization of Ionic Liquids to develop environmentally benign processes. Research on “green” solvents is a challenging task since it not only requires optimization of several properties to overcome technical challenges but also calls for economical feasibility for their process application and acceptance in industry to replace the invested current technology. The Brennecke Research Group focuses on the technical platform of this multifaceted challenge.

Through the principles of thermodynamics, several properties of such solvents can be measured and predicted. A lot of work examines the LLE or VLE of a system. Our current projects investigate the use of ionic liquids for various applications such as refrigerants, CO2 absorbents, electrochemisty and separation media.
