In this contribution the catalytic behaviour of the zeolites CsNaX-60 and CsNaX-60·8CsOH (impregnated with eight CsOH per unit cell) was studied. As a model reaction, the conversion of isopropanol to acetone as the product of basic catalysis or to propene as the product of acid catalysis was chosen. The intracrystalline self-diffusivities of isopropanol, acetone and propene in these zeolites and in NaX were measured with the pulsed field gradient (PFG) NMR technique. Self-diffusivity measurements of propane and water were performed to characterize these three zeolites. 13C MAS NMR studies with proton decoupling were used to test the cesium containing zeolites for acid or basic catalytic activity.
