ABSTRACT:
Zeolite EU-2 having a molar composition expressed by the formula: 0.5 to 1.5 R.sub.2 O: Y.sub.2 O.sub.3 : at least 70 XO.sub.2 : 0 to 100 H.sub.2 O wherein R is a monovalent cation or .sup.1
of a cation of valency n, X is silicon and/or germanium, Y is one or more of aluminium, iron, or boron, and H.sub.2 O is water of hydration additional to water notionally present where R is H, and having an X-ray pattern substantially as set out in Table 1 is prepared from a reaction mixture containing XO.sub.2 (preferably silica), Y.sub.2 O.sub.3 (preferably alumina) and a dicationic alkylated polymethylene diamine. The zeolite is useful in catalytic processes, especially for the conversion of methanol to hydrocarbons.
