Description
New zeolite materials designated Nu-6(1) and Nu-6(2), having molar compositions expressed by the formula: 0.5 to 1.5 R2O: Y2O3: at least 10 X02: 0 to 2000 H2O 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 aluminium, ion, chromium, vanadium, molybdenum, antimony, arsenic, manganese, gallium or boron, and H2O is water of hydration additional to water notionally present when R is H and having defined X-ray diffraction patterns, are prepared from a reaction mixture containing X02 (preferably silica). Y2O3 (preferably alumina) and a 4,4'-bipyridyl compound. At temperatures of 200 degrees Celsius or higher, Nu-6(1) is converted to Nu-6(2), a useful catalyst for xylenes isomerisation and the like
