SURFACTANT-MODIFIED ZEOLITES AND METHODS OF THEIR OBTAINING Russian patent published in 2014 - IPC C01B39/02 B01J20/18 

Abstract RU 2506226 C1

FIELD: chemistry.

SUBSTANCE: invention relates to field of zeolite synthesis. Surfactant modified zeolite is obtained by means of first formation of hybrid polymer from silicon alkoxide and metal alkoxide, comonomer, or both, which later interact with zeolite suspension. Zeolite suspension contains sodium, ammonium or hydrogen form of zeolite and solvent. Hybrid polymer and zeolite suspension are subjected to interaction under conditions, sufficient for sedimentation of hybrid polymer on external surface of zeolite in such a way as to form processed zeolite. Obtained zeolite is dried and annealed.

EFFECT: invention ensures obtaining zeolites with novel surface properties.
