        Kinetics of esterification of propionic acid with n-amyl alcohol in the presence of cation exchange resins

        Beyhan Erdem,Mustafa Cebe 한국화학공학회 2006 Korean Journal of Chemical Engineering Vol.23 No.6

        of n-amyl alcohol with propionic acid catalyzed by macroporous (Amberlyst-15) and micro-When these catalysts were used as commercially available, Amberlyst-15 was observed to be the most effective catalystwith respect to rate constants, but after drying it became the less effective one. The reaction rate increased with increasein catalyst concentration and reaction temperature. Stirrer speed and different mesh sizes had virtually no effect on therate under the experimental conditions. The effect of divinylbenzene content was examined for the microporous resinDowex 50 W, and the results showed that the propionic acid conversion decreased as the divinylbenzene content wasincreased. The rate data were correlated with a second-order homogeneous reaction model. The apparent activationenergies, reaction enthalpies and entropy values were calculated for each catalyst. Reaction monitoring is simple and% 2.54.
