(629o) Ionic Liquid Thin Film Technologies for Advanced Catalytic Processes

Wasserscheid, P., Friedrich-Alexander University Erlangen-Nuremberg

In the last ten years, a large number of new ionic liquid applications have been introduced to catalysis. Many of these build successfully on the unique property profile offered by these low melting salts, such as e.g. extremely low volatility, high solution power for organometallic complexes, tuneable solubility and coordination properties. It has been demonstrated for many catalytic transformations that the use of liquid salts enable processes of much higher efficiency or catalytic materials of much better functionality. Recently, rigorous attempts to minimize the amount of ionic liquid that is required to create a certain, desired “ionic liquid performance” has led to the development of “Ionic Liquid Thin Film Technologies” in catalysis.

The contribution will present preparation methods, characterization techniques and application scenarios of these technologies in catalysis. Special attention will be given to the development and use of “Supported Ionic Liquid Phase (SILP)” materials and “Solid Catalysts with Ionic Liquid Layer (SCILL)” systems. Examples will include selective C-C-linkage reactions and hydrogen production technologies.
