FIELD: molecular sieves. SUBSTANCE: invention provides molecular sieves with three-dimensional carcass structure containing [AlO2] and [PO2]. blocks. When preparing reaction mixture, its makeup is calculated such as to allow molar ratio of calibration agent to phosphorus to exceed 0.05 before aluminum-to-phosphorus molar ratio exceeded this value. EFFECT: avoided formation of viscous sludge during product preparation procedure. 16 cl, 7 ex
