MODEL DISCRIMINATION FOR REACTIONS WITH A STOP-EFFECT

Several basic models presented in the literature for reactions with a stop-effect yield virtually the same results under steady state conditions. Such a situation takes place for dehydration of alcohols and the deamination of primary amines. It has been proved that a simple transient behaviour after a stop in the supply of the reactant will not make it possible to distinguish between the models. However, a considerable difference in the mean reaction mte under forced concentration oscillations between the models can be observed. The difference decreases with an increase in the cycling time.
