Identification of Mechanism Function and Investigation on the Kinetics of Thermal Decomposition of MnC2O4

Abstract

Abstract: The thermal decomposition of MnC₂O₄was studied by means of thermogravimetry both at the constant temperature and linearly increasing temperature. Three-stage identification of the function depending on the mechanism is suggested. The experimental results and theoretical analysis show that the thermal decomposition of MnC₂O₄is dominated by an A₃mechanism. The activation energy E=103. 95 kj/mol, the frequency factor A=4. 448×10⁸min^-1. Its kinetic compensation effect is: lgA=0. 09661E-1. 2856.

Key words: Manganese oxalate, Kinetics, Thermogravimetry
