Investigation of the Kinetics and Mechanism of Decomposition of Ammonium Hydrogen Sulfate
Abstract:
The thermal decomposition of NH_4HSO_4 was studied by means of thermogravi-metry both at cosntant temperature and linearly increasing of temperature. Three-stage identification of the function depending on a mechanism was suggested. The experi-mental results and theoretical analysis showed that the thermal decomposition of NH_4HSO_4 is an one dimensional phase boundary reaction.
