    摘要: Titanovanadosilicalites have been found to be very selective, active catalysts in the epoxidation of olefins by peroxides. Dilute hydrogen peroxide suffices to afford high yields of the epoxide. Vanadium incorporation at levels of Si:V in the range 100-2500 effectively changes the characteristics of the titanosilicalite into which it is incorporated to give near quantitative conversion of propylene at selectivities greater than 90%.

    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: A process for preparing crystalline alumino-silicate compositions has been developed. The process involves preparing a charge density mismatch reaction mixture comprising sources of aluminum, silicon, optionally an E metal and at least one charge density mismatch (CDM) template. The CDM template is an organic nitrogen containing template, in the hydroxide form, e.g. tetraethylammonium hydroxide and is characterized in that it is incapable of inducing crystallization. To this mixture there is added a solution comprising a second templating agent termed a crystallization template (CT). The CT can be an organic template different from the CDM template, an alkali metal, an alkaline earth metal and mixtures thereof.

    摘要: Processes for oxidizing hydrocarbons using a new family of crystalline manganese phosphate compositions have been developed. These compositions have an extended network which network can be a one-, two-, or three-dimensional network. The composition has an empirical formula of: (Aa+)v(Mnb+)(Mc+)xPyOz where A is a structure directing agent such as an alkali metal, M is a metal such as Al, Fe3+ and “b” is the average manganese oxidation state and varies from greater than 2.0 to a maximum of 3.0. Specific oxidation processes are oxidative dehydrodimerization and oxidative dehydrogenation.
