| abstract |
The present invention relates to a process for the production of a zeolitic material having an MWW framework structure comprising YO2 and B2O3, wherein Y stands for a tetravalent element, said process comprising(i) preparing a mixture comprising 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,(iii) calcining the layered precursor obtained in (ii) for obtaining the 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, andwherein R2 and R3 are independently from each other H or alkyl, andwherein the mixture prepared in (i) and crystallized in (ii) contains 35 wt.-% or less of H2O based on 100 wt.-% of YO2 contained in the mixture prepared in (i) and crystallized in (ii), as well as to a synthetic boron-containing zeolite which is obtainable and/or obtained according to the inventive process and to its use. |
