Abstract of the Disclosure A novel crystalline aluminosilicate zeolite charac- terized by having a composition of the rollowing general formula expressed in terms of the mole ratios of oxides in the anhydrous state xM2/nO Al2O3 ySiO2 wherein M represents at least one cation having a valence of n, x is a number between 0.5 and 4, and y is a number of at least 10, and having a specific X-ray diffaction pattern. Said crystal- line aluminosilicate zeolite can be produced by maintaining a mixture or a water-soluble alkali metal compound, an N,N,N,N',N',N'-hexamethyl-1,6-hexane diammonium compound, a compound capable of giving silica under the reaction con- ditions, a compound capable of giving alumina under the reaction conditions and water, at a temperature of at least 80°C for a period sufficient to form crystals, and is useful as a catalyst for, for example, transalkylation or alkylation reaction of toluene, isomerization of xylene, isomerization of ethylbenzene to xylenes, etc.
