Abstract

The present invention relates to an organotemplate-free synthetic process for the production of a zeolitic material having a BEA framework structure comprising YO2 and optionally comprising X2O3, wherein said process comprises the steps of (1) preparing a mixture comprising seed crystals and at least one source for YO2; and (2) crystallizing the mixture; wherein Y is a tetravalent element, and X is a trivalent element, wherein the zeolitic material optionally comprises at least one alkali metal M, wherein when the BEA framework additionally comprises X2O3, the mixture according to step (1) comprises at least one source for X2O3, and wherein the seed crystals comprise zeolitic material having a BEA framework structure, preferably zeolite Beta.
