Abstract
The invention concerns IM-5 zeolite with a chemical composition with the following formula, expressed in terms of the mole ratios of the oxides for the anhydrous state: 100XO.sub.2,mY.sub.2 O.sub.3, pR.sub.2/n O where m is 10 or less; p is in the range 0 to 20; R represents one or more cations with valency n; X represents silicon and/or germanium; Y represents one or more of the following elements: aluminum, iron, gallium, boron and titanium. The zeolite is characterized by an Xray diffraction diagram, in its as synthesized state, which comprises the results shown in Table 1 of the description. The invention also concerns the preparation of the zeolite, any catalyst containing the zeolite and any catalytic process using such a catalyst.
