Abstract

A process for the preparation of a titanium-containing zeolitic material having an MWW framework structure, the process comprising (i) providing a zeolitic material having an MWW framework structure comprising SiO2 and B2O3, (ii) incorporating titanium into the zeolitic material provided in (i) comprising (ii.I) 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 an MWW framework structure from the aqueous synthesis mixture prepared in (ii.1), obtaining a mother liquor comprising the titanium-containing zeolitic material having an MWW framework structure; (iii) spray-drying the mother liquor obtained from (ii.2) comprising the titanium-containing zeolitic material having an MWW framework structure.
