| Zusammenfassung: | Zeolite substantially free from a free alkali ingredient is produced by a process wherein a silica source and an alumina source is reacted in an aqueous reaction medium containing an excessive amount of an alkali ingredient to form zeolite, followed by separating the so formed zeolite from the aqueous alkaline reaction medium or from an aqueous medium in which the zeolite, after being separated from the aqueous alkaline reaction medium, has been slurried. The separation of the zeolite from the aqueous alkaline reaction medium or from the aqueous medium, in which the zeolite has been slurried after being separated from the aqueous alkaline reaction medium, is effected in the added presence of an alkali metal or alkaline earth metal salt of aluminic acid. |
