ABSTRACT A novel synthetic zeolite material, designated zeolite EU-4, having a molar composition expressed by the formula: O to M2O : aY2O3 : at least 100 XO2 : 0 to 35 H2O wherein M is a monovalent cation or l/n of a cation of valency n, a is from 0 to 9, X is silicon and/or germanium, Y is one or more of aluminium, iron, chromium, vanadium, molybdenum, arsenic, antimony, manganese, gallium or boron, and H2O is water of hydration additional to water notionally present when M is H, and having a defined X-ray diffraction pattern is prepared from an aqueous reaction mixture containing the oxide XO2, optionally the oxide Y2O3 and an alkyltrimethyl- ammonium or dialkyldimethylammonium compound. Zeolite EU-4 is distinguished from other known zeolites by its X-ray diffraction pattern and is a useful catalyst for methanol conversion and the like.
