摘要：

Products of pre-esterification of dimethyl terephthalate with ethylene glycol at various times carried out with two catalysts, i. e. , calcium acetate and a mixture of manganese and sodium acetates, were studied. Thin-layer chromatography was used to follow the fundamental reaction and determine the type and degree of oligomerization. it was established that the manganese-sodium acetate mixed catalyst is more efficient both with regard to pre-esterification and oligomerization.
