Title: Method of preparing crystalline aluminosilicate zeolites
IPC: B01J20/18
Filed: 1980-12-23
Abstract: The preparation of crystalline aluminosilicate zeolites exhibiting the X- ray diffraction patterns characteristic of ZSM-5 zeolites is effected using conventional synthetic procedures but replacing the usual tetrapropylammonium ion source by a source of ethylenediamine which is relatively inexpensive compared with organic compounds containing tetrapropylammonium ions. Thus ZSM-5 zeolites can be produced by:   (a) preparing a mixture of water, a source of ethylene-diamine, and sources of alkali metal oxide, aluminum or gallium oxide, and silicon or germanium oxide;   (b) allowing crystals of said zeolite to form in said mixture; and   (c) recovering said crystals of zeolite.   The ZSM-5 zeolites produced in this manner can be used in catalysts for hydrocarbon conversion processes.
