Descripción
Sumario:[EN] The direct synthesis of the titanosilicate form of ITQ-39 is reported. This is the first description of the direct preparation of a titanosilicate molecular sieve containing large and medium pores in the same structure. The characterization clearly indicates the presence of Ti atoms in tetrahedral coordination in the framework of ITQ-39 zeolite. This material is very active in the oxidation of lineal and cyclic olefins with H2O2, showing selectivities between TS-1 and Ti-Beta. (C) 2012 Elsevier Inc. All rights reserved.
