Abstract: Preparation of the zeolite ZSM-5 by seeding of the starting aluminosilicate gel with the highly crystalline zeolite of the same type was studied in an aqueous-ethanolic medium. Investigated was the influence of the amount of ethanol added, of reaction temperature and time needed for crystallization of the zeolite. Suitable conditions for preparation of the zeolite ZSM-5 of high crystallinity not requiring organic templates were worked out.
