Abstract: Surface-modified zeolites and methods for preparing surface-modified zeolites are provided. A hybrid polymer formed from a silicon alkoxide and a metal alkoxide, a co-monomer, or both, is contacted with a zeolite suspension. The zeolite suspension comprises a sodium-, an ammonium-, or a hydrogen-form zeolite and a solvent. The hybrid polymer and zeolite suspension are contacted under conditions sufficient to deposit hybrid polymer on external surfaces of the zeolite to form a treated zeolite. Solvent is removed therefrom. The treated zeolite is dried and calcinated to form a dried and calcinated treated zeolite. Forming of the zeolite suspension and the contacting, removing, drying, and calcinating steps are provided in one selectivation sequence to produce a surface-modified zeolite from the ammonium-form zeolite and the hydrogen-form zeolite. If the dried and calcinated treated zeolite is a sodium-form zeolite, the sodium is exchanged with ammonium and then additionally dried and calcinated.

Abstract: A liquid or partially liquid phase process for isomerizing a non-equilibrium mixture of xylenes and ethylbenzene uses a zeolitic catalyst system preferably based on zeolite beta and on pentasil-type zeolite. The invention obtains an improved yield of para-xylene from the mixture relative to prior art processes in a more economical manner. A preferred beta zeolite is a surface-modified zeolite beta resulting from acid washing of a templated native zeolite at conditions insufficient to effect bulk dealumination. A preferred pentasil zeolite is a MTW-type with a silica-to-alumina ratio between 20 and 45.

The glass material comprises a high percent of boron trioxide which makes possible a reduced alkali oxide content. The dental glass pillars thus obtained are bio-compatible and can be used in the preparation of dental bridgework, most preferably when posterior teeth serving for support of the said bridgework are missing.

Abstract: A new family of crystalline titanostannosilicate molecular sieves have been synthesized. These molecular sieves have a microporous three-dimensional framework of TiO.sub.2, SnO.sub.2 and SiO.sub.2 tetrahedral oxide units and are represented by the empirical formula:(Ti.sub.x Sn.sub.y Si.sub.z)O.sub.2where "X", "y" and "z" are the mole fractions of Ti, Sn and Si respectively. These molecular sieves are active catalysts for the epoxidation of olefins by peroxides such as hydrogen peroxide.
