Abstract
Abstract A synthetic zeolite material, designated zeolite Nu-2 having a molar composition expressed by the formula: 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 2 0 is water of hydration additional to water notionally present when R is H and having a defined X-ray diffraction pattern. Zeolite Nu-2 is a useful catalyst for toluene disproportionation and the like.
