zeolitic material having a mww frame structure comprising boron and titanium, process for preparing such material, molding and use of a zeolitic material or molding

摘要

a process for the preparation of a zeolitic material having a mww frame structure comprising boron and titanium, the process comprising (i) providing an aqueous synthesis mixture comprising a silica source, a boron source, a titanium source and a mww modeling agent; (ii) heating the aqueous synthesis mixture to a temperature in the range from 160 to 190 ° C; (iii) subjecting the synthesis mixture (ii) to the hydrothermal synthesis conditions, obtaining in its mother liquor a precursor of the zeolitic material; (iv) separate the precursor from its mother liquor; (v) calcining the separated precursor into the zeolitic material having a frame structure mww comprising boron and titanium.
