Las preocupaciones de la presente invención un material cristalino microporoso de la naturaleza zeolítica, ITQ-39, caracterizado en que tiene, adentro calcinated a estado y en la ausencia de fallos, demostrada por la presencia de silanoles, en la red cristalina de eso, la fórmula empírica: 5 x (M 1/n XO 2): y YO 2: ¿SiO 2 en donde M se selecciona de H , un catión inorgánico de la carga de +n, y una mezcla de ambos, X es por lo menos un elemento del producto químico del estado de oxidación +3, Y es por lo menos un elemento del producto químico con el estado de oxidación +4 diferente del silicio, 10 x tiene un valor entre 0 y 0.3, incluido, y tiene un valor entre 0 y 0.1, ambo incluido, y porque el material de tipo, en el estado sintetizado, tiene un diagrama de difracción de la radiografía con, por lo menos, los valores del ángulo 2? (niveles) y intensidades relativas (I/I 0) mostradas en Tabla I, el método de preparación de eso y el uso de eso en procedimientos de la transformación, de la absorción y de la separación de compuestos orgánicos.
The present invention concerns a microporous crystalline material of zeolitic nature, ITQ-39, characterised in that it has, in calcinated state and in absence of faults, demonstrated by the presence of silanols, in the crystalline network thereof, the empirical formula: 5 x (M 1/n XO 2 ) : y YO 2 : SiO 2 wherein M is selected from H , an inorganic cation of +n charge, and a mixture of both, X is at least a chemical element of oxidation state +3, Y is at least a chemical element with oxidation state +4 different from Si, 10 x takes a value between 0 and 0.3, both inclusive,y takes a value between 0 and 0.1, both inclusive, and because the material, in synthesised state, has an X-ray diffraction pattern with, at least, the values of angle 2? (degrees) and relative intensities (I/I 0 ) shown in table I, method of preparation thereof and use thereof in processes of transformation, absorption and separation of organic compounds.
