The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Aluminum(III) sulfate xhydrate( cas:17927-65-0 ) is researched.Category: isothiazole.Papazian, H. A.; Pizzolato, P. J.; Orrell, R. R. published the article 《Thermal decomposition of aluminum sulfate and hafnium sulfate》 about this compound( cas:17927-65-0 ) in Thermochimica Acta. Keywords: sulfate aluminum hafnium thermal decomposition; kinetics decomposition aluminum hafnium sulfate. Let’s learn more about this compound (cas:17927-65-0).
The thermal decomposition of Al2(SO4)3.-nH2O and Hf(SO4)2.4H23 was studied in air by thermogravimetry and in vacuum by simultaneous thermogravimetry and evolved-gas analysis. No SO2 was detected by the mass spectrometer. The primary products of decomposition appear to be SO and O2 for both sulfates. For the Al salt, the Arrhenius relationship shows 2 activation energies, whereas for the Hf salt there is only 1 activation energy in vacuum and 2 activation energies in air. X-ray data show the solid products of the reactions to be η-Al2O3 and HfO2. The diffraction pattern for Hf(SO4)2.4H2O is presented.
After consulting a lot of data, we found that this compound(17927-65-0)Category: isothiazole can be used in many types of reactions. And in most cases, this compound has more advantages.
