(530a) Understanding and Controlling Catalytic Chemistry in the Crowded Environment of Zeolites in Liquid Phase
Water and protic solvent molecules self-organize in this environment and impact the thermodynamic state of the reacting molecules. The resulting interactions can be designed and controlled via direct synthesis (changing pore sizes and concentration of sites), as well as via the addition of cations, oxidic clusters or organic fragments. As examples for catalytic transformations elimination reactions of alcohols, alkylation of aromatic molecules and oligomerization of olefins will be compared. It will be discussed, how reaction rates and pathways can be optimized using the space available for transition states and the chemical constituents around the active site.
