Abstract
A new zeolite material designated EU-12 has a molar composition expressed by the formula: 0.5 to 2.0 R.sub.2 O: Y.sub.2 O.sub.3 : at least 5 XO.sub.2 : 0 to 1000 H.sub.2 O wherein R is a monovalent cation or 1/n of a cation of valency n, X is silicon and/or germanium, Y is one or more of aluminum, iron, chromium, vanadium, molybdenum, arsenic, antimony, manganese, gallium or boron and H.sub.2 O is water of hydration additional to water notionally present when R is H, and having an X-ray powder diffraction pattern substantially as set out in Table 1. The zeolite material is prepared from a reaction mixture containing XO.sub.2 (preferably silica), Y.sub.2 O.sub.3 (preferably alumina) and an organic compound, most preferably a tetramethylammonium compound.
