Thermochemical properties of copper forms of zeolite ZSM5 containing dimethylethylenediamine
Original language description
Synthetic zeolite ZSM5 and its copper forms containing N,N-dimethylethylenediamine (dmen) have been investigated by CHN, energy dispersive spectroscopy (EDS) analysis, X-ray powder diffractometry, X-ray photoelectron spectroscopy and continuous waves hydrogen nuclear magnetic resonance (CW H-1 NMR) spectroscopy. Thermal properties have been studied by methods of thermal analysis-TG, DTA and DTG in the temperature range 20-1000 degrees C in air atmosphere. Mass spectroscopy method was used for the studyof the released gas products of thermal decomposition. The results of thermal analyses of two zeolitic samples Cu-ZSM5 and Cu(dmen)(x)ZSM5 (x depends on the mode of preparation) demonstrated their different thermal properties. The main part of the decomposition process of the samples Cu(dmen)(x)ZSM5 occurs at considerably higher temperatures than the boiling point of dimethylethylenediamine, proving strong bond and irreversibility of dmen-zeolite interaction.

Czech description
Syntetický zeolit ZSM5 a jeho Cu-formy obsahující N,N-dimethylethylenediamin (dmen) byli studovány metodami CHN, EDS, práškovou difraktometrií, fotoelektronovou a CW H NMR spektroskopií. Termální vlastnosti byly studovány metodami TG DTA a DTG v teplotním oboru 20-1000 oC a složení uvolňovaných plynů bylo monitorováno hmotnostní spektroskopií.
