Abstract
Abstract A synthetic zeolite materiai, designated zeolite Nu-10, having a molar composition expressed by the following formula: 0.5 to 1.5 R 2 O:Y 2 O 3 : at least 20 XO 2 :O to 4000 H 2 0 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 H 2 0 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.
