1. A synthetic zeolitic material having an MFI-type framework structure obtained by a process, comprising:

  • crystallizing a mixture comprising a YO2 source and a structure directing agent comprising an alkenyltrialkylammonium cation R1R2R3R4N+-comprising compound, to obtain a zeolitic material;

    wherein Y is a tetravalent element,R1, R2, and R3 are each independently an alkyl; and

    R4 is an alkenyl;

    and whereina BET surface area of the synthetic zeolitic material determined according to DIN 66135 is from 50 to 700 m2/g, anda maximum water absorption of the synthetic zeolitic material is from 2.9 wt % to 8.7 wt %.
