The present invention refers to a microporous crystalline material of zeolitic nature named ITQ-3, to the process of preparation thereof and to the use thereof in processes of separation and transformation of organic compounds. In its calcined anhydrous state, the chemical composition of the material corresponds to the empirical formula: <CHEM> wherein x has a value lower than 0.15; it may be equal to zero; and y has a value lower than 0, 1; it 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, 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 polymorphous of silica of microporous nature. The material of this invention is also characterized by its characteristic X-ray diffraction pattern and its microporous properties. The process of preparation is characterized by the use of one or several organic additives in a reaction mixture that is made to crystallize by heating. |
