<p>ITQ-38 material, the method for the production thereof and the use thereof. The present invention relates to a crystalline material known as ITQ-38 that has a molar composition in the calcined and anhydrous state thereof that is given by the equation: x X2O3 : y YO2 : z ZO2, wherein:·X is a trivalent element selected from Al, B, Fe, In, Ga, Cr, or mixtures thereof; ·Y is a tetravalent element selected from Ti, Sn, Zr, V or mixtures thereof, preferably from Ti, Sn, Zr, or mixtures thereof; ·Z is a tetravalent element selected from Si, Ge or mixtures thereof, preferably Si; ·the value of (y+z)/x is between 9 and infinity, preferably between 20 and infinity; ·the value of z/y is between 5 and infinity, preferably between 10 and infinity, and more preferably between 10 and 150.</p> |
