zeolites with mfi structure on the basis of kieselsaeure and titanium and procedures to their synthesis.

摘要

The present invention relates to a zeolite of MFI structure, based on silicon oxide and titanium oxide and to the process for the manufacture of this compound. …??The zeolite of the invention has the formula:… (Si96-xTix)O192… in which x is between 0.1 and 6. …??It is obtained by crystallisation in an aqueous medium and in the presence of fluoride anion of a reaction mixture containing a source of titanium oxide and a source of silicon oxide. …??The zeolite of the invention is especially useful as a catalyst for the conversion of organic compounds.
