에스테르 交換反應에 對한 醋酸鹽 觸媒의 影響에 關한 硏究
孫秉淸,金德夏 弘益大學校 1982 弘大論叢 Vol.14 No.2
The transesterification reaction between dimethylphthalate and ethyleneglycol was kinetically investigated in the presence of various metal acetate catalysts at 185℃ The reaction was followed by the measurement of distilled methanol from the reaction vessel. The transesterification was found to obey thiry-order kinetics with respect to dime thylphthalate and ethyleneglycol and catalyst. From the examination of relationship between rate constants and reciprocal absolute temerature, the activation evergy has been calculate as 25.90 Kcal with cobalt acetate catalyst. The highest reactivities were found for the metal acetate catalysts with the electron egativity values between 1.4 and 1.7.
