SYNTHESIS OF ITQ-17 IN THE ABSENCE OF FLUORIDE IONS

摘要

The invention relates to a crystalline material which is characterised in that contains no fluorides, said material having a composition in the calcined state that corresponds to that of the material known as ITQ-17. Moreover, said material is characterised in that has a composition on an anhydrous basis and in terms of oxide moles when synthesised, without calcination, represented by the formula: xX2O3: (1-z)YO2: zGeO2: r/n RnO, wherein: X is at least one trivalent element; Y is one or more tetravalent elements which are different from germanium; R is a structure-directing organic compound, preferably cation l-methyl-4-Aza, 1-azoniabicyclo [2.2.2.] octane (DABMe<+>) or cation 1,4-bis [N-(4-aza,1-azoniabicyclo [2,2,2] octane) methyl] benzene (d-DABBz)<2+>; x varies between 0 and 0.02; z is between 0.02 and 0.67; r varies between 0.01 and 0.5; and n is 1 or 2. The invention also relates to a method of synthesising said material and the material thus obtained which is subjected to a post-synthesis step in order to eliminate the organic component from the structure thereof.
