ARTICLE TITLE : A kinetics study in CSTR using simultaneous temperature scanning and composition modulation: The alkaline hydrolysis of ethyl acetate


ABSTRACT: This work presents a new technique for reaction kinetic studies of liquid phase reactions in a CSTR. By simultaneously varying the reaction temperature (temperature scanning - TS) and reactant feed concentration (composition modulation - CM) while recording the output concentration, the technique allows, through the least-square fitting of computer-generated model data to the experimental time-series, to obtain from a single experiment the reaction orders as well as both Arrhenius parameters. The alkaline hydrolysis of ethyl acetate was chosen to illustrate the technique, assuming a rate law in the form of a simple power law. The set of parameters that resulted in the minimum sum of squared errors was selected. These values were very close to those reported in literature. The technique saves much time and experimental resources.
