Abstract

Abstract A synthetic zeolite material, designated zeolite Nu-4, having a molar composition expressed by the formula: 0.1 to 7.5 M 2 O:0.2 to 2.5 Y 2 0 3 :100 X0 2 :0 to 50 H 2 0 wherein M' is a monovalent cation or 1/n of a cation of valency n, X is silicon or germanium, Y is aluminium, iron, chromium, vanadium, molybdenum, arsenic, antimony, manganese, gallium, or boron, and H 2 0 is water of hydration additional to water notionally present when M 1 is H and having a defined X-raypattem is prepared from defined aqueous mixtures containing the oxide XO 2 , the oxide Y 2 O 3 and a polyalkylene polyamine. The zeolite is a useful catalyst for xylenes isomerisation and the like.
