A new zeolite material designated EU-1 having a molar composition expressed by the formula: 0.5 to 1.5 R2O:Y2O3: at least 10 XO2:0 to 100 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 aluminum, iron, gallium or boron, and H2O is water of hydration additional to water notionally present when R is H, and having an X-ray pattern substantially as set out in Tables 1 and 2 is prepared from a reaction mixture containing XO2 (preferably silica), Y2O3 (preferably alumina) and a dicationic alkylated polymethylene diamine. The new zeolite is useful in catalytic processes, especially xylenes isomerization. |
