Abstract:
A process comprising hydrothermally synthesizing a titanium-containing zeolitic material having framework type MWW in the presence of an MWW template compound, obtaining a mother liquor comprising water, a first portion of the MWW template compound and a titanium-containing zeolitic material having framework type MWW comprising a second portion of the MWW template compound, separating the first portion of the MWW template compound from the mother liquor and recycling the first portion of the MWW template compound into a hydrothermal synthesis of a titanium-containing zeolitic material having framework type MWW.
