Název v původním jazyce

Thermal Decomposition of Aluminium Chloride Hexahydrate

Popis výsledku v původním jazyce

The decomposition rate of aluminum chloride hexahydrate (AlCl3.6H2O) was measured as weight loss at ambient pressure and elevated temperatures up to 270oC. Such incomplete, thermal decomposition produces a porous and reactive basic aluminum chloride [Al2O3.2HCl.2H2O or Al2(OH)4Cl2.H2O] which dissolves in water to give poly(aluminum chloride) used as an efficient flocculation agent. A slowly rising-temperature method and very small sample masses, which minimize heat and mass transfer intrusions, were employed to determine intrinsic reaction rates. A fractional order kinetic equation of Arrhenius type was proposed for the decomposition and tested also against the results amassed by experiment in a constant temperature mode. This correlation allows the estimation of the reaction rate as a function of temperature and the extent of decomposition. It can readily be employed in modeling and simulation of the decomposition process.
