Stannosilicate molecular sieves |
摘要 |
A new family of stannosilicate molecular sieves which have the zeolite beta structure are disclosed. These molecular sieves have a three dimensional framework structure composed of at least SnO2 and SiO2 tetrahedral oxide units (and optionally TiO2 and GeO2 units) and have an empirical formula of:(SnxTiySi1-x-y-zGez)O2where "x", "y" and "z" are the mole fractions of tin, titanium and germanium respectively. A process for preparing these molecular sieves is also presented along with processes for the selective oxidation of organic compounds with peroxides using the molecular sieves as catalysts.
