Abstract
A synthetic zeolite material, designated zeolite Nu-5, having a molar composition expressed by the formula; 0.5 to 1.5 R.sub.2 O: Y.sub.2 O.sub.3 : at least 10 XO.sub.2 : 0 to 2000 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 aluminium, iron, chromium, vanadium, molybdenum, arsenic, manganese, gallium or boron, and H.sub.2 O is water of hydration additional to water notionally present when R is H, and having a defined X-ray diffraction pattern. Zeolite Nu-5 is a useful catalyst.
