Abstract
In this work we present theoretical and experimental studies of a laboratory scale continuous flow stirred tank reactor (CSTR) in which theiron-(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. © Copyright 2004 Elsevier Science B.V., Amsterdam. All rights reserved. [accessed 2014 March 31st]
