A Study on the transesterification reaction between diethanolamine and dimethylphthalate

The transesterification reaction between diethanolamine and dimethylphthalate was kinetically investigated in the presence of various metal acetate catalysts at $130^{\circ}C$. The reaction was followed by the measurement of distilled methanol from the reaction vessel. The transesterification was found to obey first-order kinetics with respect to the concentration of diethanolamine and dimethylphthalate and catalyst, respectively. The reactivities has highest value where the electronegativity and instability constand (Kij) values for the metal acetate catalysts are about 1.6.
