Synthetic zeolite ZSM5 and its copper forms containing ethylenediamine (en)
have been investigated by X-ray powder diffractometry, NMR and X-ray photo
electron spectroscopies, CHN, EDS and thermal analyses. Copper cations exch
anged into the channels of synthetic zeolite ZSM5 formed coordination compl
exes with ethylenediamene. By different modes of preparation we obtained th
ree Cu-en-ZSM5 zeolitic products with different composition, colour and oth
er properties. The content of the ethylenediamine in the zeolitic products
was 1.5-6 wt.% (dependent of the mode of preparation).
