Abstract

The present invention relates to a process for the production of a boron-containing zeolitic material having an MWW framework structure comprising YO2 and B2O3, wherein Y stands for a tetravalent element, wherein said process comprises(a) providing a mixture comprising one or more sources for YO2, one or more sources for B2O3, 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) R1R2R3N  (I) wherein R1 is (C5-C8)cycloalkyl, and wherein R2 and R3 are 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.
