ABSTRACT:
Zeolite Nu-10 is prepared from a reaction mixture containing at least one oxide XO.sub.2 (where X is preferably silicon), at least one oxide Y.sub.2 O.sub.3 (where Y is preferably aluminium), and, optionally at least one organic compound selected from (i) compounds of formula L.sup.1 --(CH.sub.2).sub.n --L.sup.2 where L.sup.1 and L.sup.2 independently represent a hydroxyl group or an optionally substituted amino group and n is an integer from 2 to 20, provided that when both L.sup.1 and L.sup.2 are optionally substituted amino groups, n is an integer from 6 to 20 and (ii) heterocyclic bases. Preferred organic compounds are diamines, diols and heterocyclic di- or mono-amines. The reaction mixture also includes an alkali metal hydroxide, sodium, potassium and rubidium being particularly suitable.
Zeolite Nu-10 is useful as a catalyst for various hydrocarbon conversion reactions, for the conversion of small oxygen-containing organic molecules to hydrocarbons and as an agent for the removal of organic compounds from aqueous effluents.
