    摘要: 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.

    摘要: This invention relates to hydrocarbon conversion processes using a novel crystalline metallo manganese oxides that have the hollandite structure. The composition is represented by the formula A.sub.y Mn.sub.8-x M.sub.x O.sub.16 where A is a templating agent such as potassium, ammonium, and y varies from about 0.5 to about 2.0, M is a metal such as chromium, vanadium, gallium, antimony and x varies from about 0.01 to about 4.0. These oxides have a three-dimensional structure with manganese and the M metals forming the framework. Examples of the processes in which these compositions can be used are oxydehydrogenation and ammoxidation. These compositions are also effective for oxidizing cyanide in aqueous streams.
