Abstract "Zeolites" A novel synthetic zeolite material, designated zeolite Nu-10, having a molar composition expressed by the following formula: 0.5 to 1.5 R2O : Y2O3 : at least 20 XO2 : 0 to 4000 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, iron, chrome, vanadium, molybdenum, arsenic, antimony, manganese, gallium or boron, and H2O is water of hydration additional to water notionally present when R is H, and having a defined X-ray pattern. Zeolite Nu-10 is a useful catalyst for toluene methylation and the like and is distinguished from other zeolites by its X-ray diffraction pattern and infra-red spectrum. |
