Abstract

A new material of zeolitic nature, ITQ-6, has been obtained by delamination of a layered precursor of ferrierite. XRD, Ar and N-2 adsorption, and Si-29 and Al-27 MAS NMR pyridine and 2,6-di-tert-butylpyridine adsorption showthat a delaminated material with a very high external surface area has been produced. The silicoaluminate is stable upon calcination and presents strong acid sites catalytically active and highly accessible to bulky reactants. We have also obtained by direct synthesis the titanium silicate version of the laminar precursor of ferrierite and ITQ-6. The Ti is demonstrated tobe in framework positions, and in the case of the TiITQ-6 is active and selective in the epoxidation of I-hexene with H2O2 The TiITQ-6 is stable and remains active upon repeated reaction-calcination processes.
