An oscillating liquid–gas reaction with periodic evaporation: nonlinear analysis and experimental results

In this work we present theoretical and experimental studies of a laboratory scale continuous flow stirred tank reactor (CSTR) in which the iron-(III)-nitrate catalyzed oxidation of ethanol with hydrogen peroxide to ethanal and acetic acid takes place. This reaction displays temperature and concentr...

Description
Summary:In this work we present theoretical and experimental studies of a laboratory scale continuous flow stirred tank reactor (CSTR) in which the iron-(III)-nitrate catalyzed oxidation of ethanol with hydrogen peroxide to ethanal and acetic acid takes place. This reaction displays temperature and concentration oscillations when it is performed in a CSTR. A liquid-phase model is known in the literature derived from a more detailed mechanism. This model predicts the location of stationary solutions and bifurcations well, but the calculated reactor temperatures are high above the boiling point of the reaction mixture under certain conditions. Therefore, two different gas/liquid models were developed and compared with the experimental results.
