Kinetics of isothermal decomposition of copper (II)‎ and cobalt salts of itaconic acid

الملخص EN

Differential thermal analysis-thermogravimetric techniques were used to study the thermal decomposition of the copper (II) and cobalt salts of itaconic acid.

The kinetics of the isothermal decomposition were studied in air over the temperature ranges 60-120ºC, 200-310ºC and 250-370ºC for the three decomposition steps of dehydration, and decomposition to oxide (in two steps).

Kinetic analysis of the isothermal data were discussed according to various theoretical kinetic models of heterogeneous reactions.

The results showed that the phase boundary (R3) and the first order (F1) models give the best fit data.

The isothermal activation parameters calculated according to (R3) were compared and discussed with those obtained under non-isothermal techniques.
