Abstract
Synthetic zeolite ZSM5 and its copperforms containing ethylenediamine (en) have beeninvestigated by X-ray powder diffractometry, NMR andX-ray photoelectron spectroscopies, CHN, EDS andthermal analyses. Copper cations exchanged into thechannels of synthetic zeolite ZSM5 formed coordinationcomplexes with ethylenediamene. By different modes ofpreparation we obtained three Cu-en-ZSM5 zeoliticproducts with different composition, colour and otherproperties. The content of the ethylenediamine in thezeolitic products was 1.5–6 wt.% (dependent ofthe mode of preparation).
