Preparing MFI structural type zeolite, useful e.g. as catalyst support, adsorbent or separation agent, comprises mixing source of tetravalent element and quaternary amine compound in aqueous medium and hydrothermal treatment of mixture

摘要

Preparation of MFI structural type zeolite comprises: mixing at least one source of at least one tetravalent element X and at least one quaternary amine compound (I), in an aqueous medium; and hydrothermal treatment of the obtained mixture until the MFI structural type zeolite is formed. Preparation of MFI structural type zeolite comprises: mixing at least one source of at least one tetravalent element X and at least one quaternary amine compound of formula (I), in an aqueous medium; and hydrothermal treatment of the obtained mixture until the MFI structural type zeolite is formed. n : number of methylene group comprising 4 or 5; R 1>, R 2>alkyl group of formula (C aH 2a+1); and a : 2-7.
