Patent

CA 2452840

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.

L'invention concerne un matériau cristallin qui ne contient pas de fluorures, qui présente une composition à l'état calciné correspondant à celle du matériau appelé ITQ-17 et qui présente une composition sur une base anhydre et en termes de moles d'oxydes lorsqu'il est synthétisé, sans calcination, laquelle composition est représentée par la formule : xX¿2?O¿3?: (1-z)YO¿2?: zGeO¿2?: r/n R¿n?O, dans laquelle : X représente au moins un élément trivalent, Y représente un ou plusieurs éléments tétravalents différents de germanium, R représente un composé organique directeur de structure, de préférence le cation l-méthyl-4-Aza, 1-azoniabicyclo [2.2.2.] octane (DABMe?+¿) ou le cation 1,4-bis [N-(4-aza,1-azoniabicyclo [2,2,2] octane) méthyl]benzène (d-DABBz)?2+¿. x vaut de 0 à 0,02, z est compris entre 0,02 et 0,67, r est compris entre 0,01 et 0,5, et n vaut 1 ou 2. L'invention concerne également un procédé permettant de synthétiser ledit matériau, ainsi que matériau à l'aide dudit procédé et soumis à une étape post-synthèse afin d'éliminer le composant organique de sa structure.
