Kinetic Parameters Determination Using Reaction Calorimetry： Study of Sodium Benzoate Synthesis
Kinetic Parameters Determination Using Reaction Calorimetry： Study of Sodium Benzoate Synthesis
摘要
A modified systematic approach to determination of the kinetics of well known reaction from calorimetric data is addressed in this study. Because the application of calorimetry does not depend upon knowledge of concentration profiles, it has the advantage over other real-time analyses. Estimated kinetic parameters were compared with the ones obtained with Fourier Transform Infrared Spectroscopy （FTIR）. The chosen reaction was ethyl benzoate saponification performed in homogeneous reaction medium, although it is known as heterogeneous reaction. Thus, the rate expression was developed where no mass transfer is considered. The reaction was carried out in a MettlerTM RCI reaction calorimeter.
