CA 2447890

A new synthetic porous crystalline material, designated ITQ-12, is disclosed having, in its calcined form, the X-ray diffraction pattern of Table 2 above. Also disclosed are methods of making ITQ-12 in its silicate, aluminosilicate and borosilicate forms in the presence of HF using 1,3,5-trimethylimidazole as a directing agent and hydolyzed tetraethylorthosilicate as a silicate source. ITQ-12 is useful in the conversion of methanol to olefins and as an adsorbent.

L'invention concerne un nouveau matériau poreux cristallin synthétique, appelé ITQ-12, présentant, sous sa forme calcinée, le motif de diffraction de rayons X correspondant au Tableau 2 donné dans la description. L'invention concerne également des procédés de production de ITQ-12 sous forme de silicate, d'aluminosilicate et de borosilicate, en présence de HF, à l'aide de 1,3,5-triméthylimidazole, en tant qu'agent directeur, et de tétraéthylorthosilicate hydrolysé, en tant que source de silice. L'ITQ-12 est utile dans la conversion de méthanol en oléfines et en tant qu'adsorbant.
