Abstract

A process for preparing a molding comprising zinc and a titanium-containing zeolitic material having framework type MWW, comprising (i) providing a molding comprising a titanium-containing zeolitic material having framework type MWW; (ii) preparing an aqueous suspension comprising a zinc source and the molding comprising a titanium-containing zeolitic material having framework type MWW prepared in (i); (iii) heating the aqueous suspension prepared in (ii) under autogenous pressure to a temperature of the liquid phase of the aqueous suspension in the range of from 100 to 200° C., obtaining an aqueous suspension comprising a molding comprising zinc and a titanium-containing zeolitic material having framework type MWW; (iv) separating the molding comprising zinc and a titanium-containing zeolitic material having framework type MWW from the liquid phase of the suspension obtained in (iii).
