Abstract: A process for preparing a zeolitic material comprising Ti, having framework type CHA and having a framework structure which comprises Si and O, said process comprising (i) preparing a pre-synthesis mixture comprising water, a CHA framework structure directing agent, and a zeolitic material comprising Ti, having framework type MFI and having a framework structure which comprises Si and O; (ii) removing water from the pre-synthesis mixture obtained from (i) by heating the pre-synthesis mixture to a temperature of less than 100° C. at a pressure of less than 1 bar (abs); (iii) hydrothermally crystallizing the zeolitic material comprising Ti, having framework type CHA and having a framework structure which comprises Si and O.

Abstract: A process for preparing a zeolitic material containing YO2 and X2O3, where Y and X represent a tetravalent element and a trivalent element, respectively, is described. The process includes (1) a step of preparing a mixture containing one or more structure directing agents, seed crystals, and a first zeolitic material containing YO2 and X2O3 and having FAU-, GIS-, MOR-, and/or LTA-type framework structures; and (2) a step of heating the mixture for obtaining a second zeolitic material containing YO2 and X2O3 and having a different framework structure than the first zeolitic material. The mixture prepared in (1) and heated in (2) contains 1000 wt % or less of H2O based on 100 wt % of YO2 in the framework structure of the first zeolitic material. A zeolitic material obtainable and/or obtained by the process and its use are also described.

Abstract: Provided is a crystalline layered silicate, having an X-ray diffraction pattern comprising reflections at 2-theta values of (5.3±0.2)°, (8.6±0.2)°, (9.8±0.2)°, (21.7±0.2)° and (22.7±0.2). Also provided are a process for preparing the crystalline layered silicate and uses of the layered silicate. The process comprises steps of: (i) preparing a synthesis mixture comprising water, a source of Si, and a structure directing agent comprising a diethyldimethylammonium compound; (ii) subjecting the synthesis mixture obtained from (i) to hydrothermal synthesis conditions comprising heating the synthesis mixture obtained from (i) to a temperature in the range of from 110 to 180° C. and keeping the synthesis mixture at a temperature in this range under autogenous pressure for 1 to 6 days, obtaining a mother liquor comprising the crystalline layered silicate.
