The dehydration of cyclohexanol on zeolite Beta in water was studied combining kinetic measurements with in situ NMR spectroscopy to qualitatively and quantitatively describe the reaction. Concluded to be of E1 type, it was 100 times faster in the zeolite than catalyzed by aqueous H
3PO
4. The acid site distribution in the zeolite was determined by combining EXAFS and
27Al MAS NMR spectroscopy. The presence of hot water did not change the active site geometry initially, but led finally to complete framework degradation via selective hydrolysis of links between zeolite tetrahedra.
