Synthesis and catalytic properties of large-pore Sn-β and Al-free Sn-β molecular sieves

Abstract

Sn-β and Al-free Sn-β (large pore, 12-membered ring channels) molecular sieves prepared by hydrothermal synthesis and characterised by XRD, FTIR and sorption techniques are distinguished by their acidic and oxidation properties, in the acetylation of 1,3,5-trimethylbenzene (1,3,5-TMB) with acetyl chloride and in the oxidation of m-cresol and 1,3,5-TMB with aqueous H₂O₂, respectively.
