| 摘要 |
The present invention refers to a crystalline material of zeolitic nature named ITQ-3 characterized by its characteristic X-ray diffraction pattern and its microporous properties, to the process of preparation thereof characterized by the use of one or several organic additives in a reaction mixture that is made to crystallize by heating and to the use thereof in processes of separation and transformation of organic compounds, which material has the empirical formula x(M1/nXO2):yYO2:SiO2 where x has a value lower than 0.15 and may be equal to zero; and y has a value lower than 0.1 and may be equal to zero; M is H+ or an inorganic cation of charge +n, X is a chemical element with oxidation state (Al, Ge, B and Cr), Y is a chemical element with oxidation state (Ti, Ge and V), and when x=0 and y=0 can be described as a new polymorphous of silica of microporous nature.
