摘要：

The importance of oligomerization during the reaction between dimethyl terephthalate and ethylene glycol was analysed by using as the only observed variable the methanol withdrawn from the reactor. Data obtained under a wide range of experimental conditions were used. Models including oligomerization reactions were used to fit experimental data and their performance compared by means of the χ2 test with a model including only the ester interchange reaction. Contrary to what previous authors have reported, it is concluded that more observed variables are needed to elucidate the significance of oligomerization reactions. © 1990.
