Synthesis of the Ti−Silicate Form of BEC Polymorph of β-Zeolite Assisted by Molecular Modeling

The K+ free pure silica form of polymorph C (BEC) of β-zeolite has been synthesized with a cationic organic structure directing agent (SDA) that was predicted best, out of a series of nine potentials, by means of modeling techniques. On the bases of this synthesis method, the Ti−BEC zeolite has been obtained which owing to the pore topology and dimensions shows a higher epoxidation activity than the Ti−β-polymorph either with H2O2 or organic peroxides as oxidants.
