FIELD: chemistry.
SUBSTANCE: invention relates to the synthesis of zeolite ZSM-5. First, a nanocrystal seed ZSM-5 with the particle size 70-300 nm is obtained. The seed in an amount of 0.1-6.0% is added to mother liquor, which includes water-soluble glass as a silicon dioxide source, an aluminium oxide source, a neutralising agent and water. The reaction mixture is kept at a temperature of 150-200°C for its crystallisation.
EFFECT: invention makes it possible to synthesise small and uniform in size ZSM-5 crystals, which do not contain admixtures.
