A zeolitic solid crystal, designated IM-9 presenting an illustrated X-ray diffraction diagram (figure 1), has a chemical composition expressed on an anhydride base, in terms of the mole of oxides, defined by the following general formula: XO2:m YO2:p Z2O3:q R2/nO:s F (I) in which R represents one or more cations of valence n, X represents one or more tetravalent elements different to germanium, Y represents germanium, Z represents at least one trivalent element, F is the fluorine, m, p, q, s represent respectively the number of moles of the YO2, Z2O3, R2/nO and F and m is between 0.1 and 0.9, p is between 0 and 0.5, q and s are between 0.01 and 0.7. The ratio ((1+m)/p) is greater than or equal to 5. An Independent claim is also included for the preparation of the above zeolitic solid crystal IM-9. |
