Abstract: Described herein is a process for producing a zeolitic material having an MWW framework structure containing YO2 and B2O3, in which Y stands for a tetravalent element. The process includes the steps of (i) preparing a mixture containing one or more sources for YO2, one or more sources for B2O3, 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.
