PROCESS FOR PREPARING TITANIUM-CONTAINING ZEOLITIC MATERIAL HAVING MWW FRAMEWORK STRUCTURE Russian patent published in 2018 - IPC C01B39/04 C01B39/06 

FIELD: biochemistry.

SUBSTANCE: invention relates to the synthesis of zeolitic materials. Disclosed is a method for producing a titanium-containing zeolite material having a MWW framework structure. Method includes: (i) providing a zeolitic material having MWW framework structure comprising SiO₂ and B₂O₃, (ii) incorporating titanium into the zeolitic material provided in (i) comprising (ii.1) preparing an aqueous synthesis mixture containing the zeolitic material provided in (i), an MWW template compound and a titanium source, (ii.2) hydrothermally synthesizing a titanium-containing zeolitic material having a MWW framework structure from the aqueous synthesis mixture prepared in (ii.1), obtaining a mother liquor comprising the titanium-containing zeolitic material having a MWW framework structure; (iii) spray-drying the mother liquor obtained from (ii.2) comprising the titanium-containing zeolitic material having a MWW framework structure.

EFFECT: method is proposed for the production of a titanium-containing zeolitic material having a MWW framework structure.
