The present invention relates to a process for the production of a zeolitic material having an MWW framework structure comprising YOand BO, wherein Y stands for a tetravalent element, said process comprising

Solidothermal synthesis of a boron-containing zeolite with an MWW framework structure

Described herein is a process for producing a zeolitic material having an MWW framework structure containing YOand BO, in which Y stands for a tetravalent element. The process includes the steps of (i) preparing a mixture containing one or more sources for YO, one or more sources for BO, one or more organotemplates, and seed crystals, (ii) crystallizing the mixture obtained in (i) for obtaining a layered precursor of the MWW framework structure, and (iii) calcining the layered precursor obtained in (ii) for obtaining the zeolitic material having an MWW framework structure. Also disclosed herein are synthetic boron-containing zeolites obtain by the process and uses thereof.

The present invention relates to a process for the production of a boron-containing zeolitic material having an MWW framework structure comprising YOand BO, wherein Y stands for a tetravalent element, wherein said process comprises (a) providing a mixture comprising one or more sources for YO, one or more sources for BO, one or more organotemplates, and seed crystals, (b) crystallizing the mixture obtained in (a) for obtaining a layered precursor of the boron-containing MWW-type zeolitic material, (c) calcining the layered precursor obtained in (b) for obtaining the boron-containing zeolitic material having an MWW framework structure, wherein the one or more organotemplates have the formula (I)RRRN&#x2003;&#x2003;(I)wherein Ris (C-C)cycloalkyl, andwherein Rand Rare independently from each other H or alkyl, as well as to a synthetic boron-containing zeolite which is obtainable and/or obtained according to the inventive process as well as to its use.
