Beschreibung
Zusammenfassung:	A process for producing a crystalline aluminosilicate zeolite characterized by having (a) a silica/alumina mole ratio of from 10 to 100, (b) X-ray lattice distances d shown in Table A of the specification, and (c) a specific n-hexane adsorption, under limited measuring conditions, of at least 0.07 g/g, which comprises maintaining a silica source, an alumina source, and a zeolite selected from zeolites ZSM-5 and zeolites having said characteristics, in an aqueous solution containing 1 to 200 millimoles, per gram of said zeolite, of an alkali metal hydroxide under such temperature, pressure and time conditions as to produce a crystalline aluminosilicate zeolite; and a crystalline aluminosilicate zeolite characterized by having aforesaid properties (a) to (c) and (d) a (2-methylpentane/cyclohexane) adsorption ratio of from 1.1 to 1.6.
