Abstract

Zeolita ITQ-4. La presente invención se refiere a un material cristalino microporoso de naturaleza zeolítica denominado ITQ-4, 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{sub,1/n XO{sub,2 ):yYO{sub,2 :SiO{sub,2 donde x posee un valor inferior a 0.15, pudiendo ser igual a cero: y tiene un valor inferior a 0.1, pudiendo ser igual a cero: M es H{sup,+ 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 característico y sus propiedades microporosas. 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.Zeolite ITQ-4. The present invention refers to a microporous crystalline material of a zeolitic nature called ITQ-4, to the process of its preparation and to its use in processes of separation and transformation of organic compounds. In the calcined and anhydrous state, the chemical composition of the material corresponds to the empirical formula: x (M {sub, 1 / n XO {sub, 2): yYO {sub, 2: SiO {sub, 2 where x has a lower value to 0.15, being able to be equal to zero: and having a value less than 0.1, being able to be equal to zero: M is H {sup, + or an inorganic cation of charge + n: X is a chemical element of oxidation state +3 (Al, Ga, B, Cr) and Y is a chemical element with oxidation state +4 (Ti, Ge, V). When x = 0 and y = 0 the material can be described as a new polymorphic form of silica with a microporous character. The material of this invention is also characterized by its characteristic X-ray diffraction pattern and its microporous properties. The preparation process is characterized by the use of one or more organic additives to a reaction mixture that is crystallized by heating.
