Estimating the term…
The present invention relates to a process for the preparation of a zeolitic material comprising the steps of: (1) providing a mixture comprising one or more sources for YO2 and one or more alkenyltrialkylammonium cation R1R2R3R4N+-containing compounds as structure directing agent; and (2) crystallizing the mixture obtained in step (1) to obtain a zeolitic material; wherein Y is a tetravalent element, and wherein R1, R2, and R3 independently from one another stand for alkyl; and R4 stands for alkenyl, as well as to zeolitic materials which may be obtained according to the inventive process and to their use.
A process for preparing a zeolitic material, the process comprising:
A synthetic zeolitic material having an MFI-type framework structure comprising YO2 and optionally comprising X2O3,
A synthetic zeolitic material having an MFI-type framework structure comprising YO2 and optionally comprising X2O3,
42-43. (canceled)
