METHOD OF PRODUCING NaA OR NaX ZEOLITE (VERSIONS) Russian patent published in 2012 - IPC C01B39/20 C01B39/16 

Abstract RU 2452688 C1

FIELD: chemistry.

SUBSTANCE: method of producing NaA or NaX zeolites involves preparation of sodium metasilicate and sodium aluminate solutions, adding an amine-containing compound into the solution, said amine-containing compound being selected from: triethanolamine, polyethylene polyamine or m-phenylenediamine, and preparation of gel by mixing the obtained solutions. The gel is mixed with dimethyl sulphoxide and hydrothermal crystallisation is carried out at temperature 70-100°C. Gels of given composition are prepared in order to produce NaA and NaX zeolites.

EFFECT: obtaining monophase NaA or NaX zeolites with negligible content of impurities.
