Extracting Kinetic Information Using Power Measurements From Isothermal Calorimeters.

In this study, we demonstrate that both the heat of reaction and kinetic constants of a single chemical reaction can be estimated from a temporal power measurement derived from an isothermal reaction calorimeter. Appropriate mathematical models are developed to extract kinetic information. Both the...

Sumario:In this study, we demonstrate that both the heat of reaction and kinetic constants of a single chemical reaction can be estimated from a temporal power measurement derived from an isothermal reaction calorimeter. Appropriate mathematical models are developed to extract kinetic information. Both the batch and semi-batch mode of operation are considered. The derived equations are applied to the hydrolysis reaction of acetic anhydride so as to estimate enthalpy of reaction, kinetic constants and activation energy. The values estimated compare well with those already reported in the literature.
