Zeolita ITQ-1

Authors: Díaz Cabañas, María José; Camblor, Miguel Ángel; Corell, Catalina; Corma, Avelino;
Abstract

La presente invención se refiere a un material cristalino microporoso de naturaleza zeolítica denominado ITQ-1, al procedimiento de su preparación y a su utilización en procesos de separación y transformación de compuestos orgánicos. En estado calcinado y anhidro, la composición química del material corresponde a la fórmula empírica: x(M_1/n XO_2): y YO2:SiO2 donde x posee un valor inferior a 0,02, pudiendo ser igual a cero; y tiene un valor inferior a 0,04, pudiendo ser igual a cero; M es H+ o un catión inorgánico de carga +n; X es un elemento químico de estado de oxidación +3 (Al, Ga, B, Cr) e Y es un elemento químico con estado de oxidación +4 (Ti, Ge, V). Cuando x = 0 e y = 0 el material puede describirse como una nueva forma polimórfica de la sílice de carácter microporoso. El material de esta invención se caracteriza también por su patrón de difracción de rayos X. El proceso de preparación se caracteriza por el uso de uno o varios aditivos orgánicos a una mezcla de reacción que se hace cristalizar mediante calentamiento.
