FIELD: chemistry.SUBSTANCE: invention relates to field of zeolite adsorbent production. Method of obtaining NaY zeolite includes preparation of water mixture from oxides of sodium, silica and aluminium, which contains 1-5.0 M of phenylene diamine, hesating mixture to temperature of crystallisation, exposure at said temperature until crystals are obtained and separation of crystals from solution. Mole ratios of oxides in mixture constitute: NaO/SiO1.6-2.2; SiO/AlO1.5-5; HO/NaO 70-150.EFFECT: invention ensures obtaining zeolite of faujasite structure - NaY with SiO/AlOratio higher than 3,1 and with size of crystals not less than 20 mcm.1 dwg, 1 tbl |
