Abstract

The reaction between ammonium sulphate with aluminium oxide was studied. It was confirmed by X-ray diffraction and chemical analysis that three intermediate reaction products, (NH4)3Al(SO4)3, NH4Al(SO4)2 and Al2(SO4)3, are formed. The thermal decompositions of these three compounds were carried out. It has been shown that the same rate law is valid for them. The activation energies for (NH4)3Al(SO4)3, NH4Al(SO4)2 and Al2(SO4)3 are 95.9, 177.9 and 291.0 kj/mol, respectively.

Zusammenfassung

Die Reaktion von Ammoniumsulfat mit Aluminiumoxid wurde untersucht. Durch Röntgendiffraktion und chemische Analyse wurde bestätigt, daß drei Zwischenprodukte (NH4)3Al(SO4)3, NH4Al(SO4)2 und Al2(SO4)3 gebildet werden. Die thermische Zersetzung der drei Verbindungen wurde durchgeführt. Es wurde gezeigt, daß für alle drei dasselbe Geschwindigkeitsgesetz Gültigkeit hat. Die Aktivierungsenergien für (NH4)3Al(SO4)3, NH4Al(SO4)2 und Al2(SO4)3 sind 95.9, 177.9 und 291.0 kJ/Mol.

Резюме

Изучена реакция межд у сульфатом аммония и окисью алюминия. С пом ощью рентгено-диффракцио нного анализа и химич еского анализа подтвержден о образование трех промежуточных п родуктов реакции: (NH4)3Al(SO4)3, NH4Al(SO4)2 и Al2(SO4)3. Проведено термическое разложе ние этих трех соедине ний, и установлено, что для с облюдается один и тот же закон ско рости. Значения энерг ии активации соединени й (NH4)3Al(SO4)3, NH4Al(SO4)2 и Al2(SO4)3, соответстве нно, равны 95.9; 177.9 и 291.0 кдж. моль−1.
