<p>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 (III 0 ) shown in table I, method of preparation thereof and use thereof in processes of transformation, absorption and separation of organic compounds.</p> |
