METHOD OF PRODUCING MWW-ZEOLITIC MATERIAL CONTAINING BORON AND TITANIUM Russian patent published in 2019 - IPC C01B39/48 C01B39/12 C01B39/08 B01J29/89 

FIELD: chemistry.

SUBSTANCE: invention relates to synthesis of MWW-type zeolites and use thereof. Method of producing zeolite material having a MWW framework structure and containing boron and titanium, where this method includes: (i) providing an aqueous synthesis mixture containing a silicon dioxide source, a boron source, a titanium source and a template agent to form a MWW structure; (ii) heating said aqueous mixture for synthesis to a temperature in range of 160 to 190 °C; (iii) exposing the synthesis mixture from step (ii) to hydrothermal synthesis conditions to obtain a zeolitic material precursor in its mother solution; (iv) separating said precursor from its mother solution; (v) calcining the recovered precursor to obtain zeolite material having a MWW framework structure and containing boron and titanium.

EFFECT: invention enables simple synthesis of zeolite MWW containing boron and titanium.
