Abstract

Описывается способ непрерывной переэтерификации диметил- или диэтилтерефталата с этиленгликолем, пропиленгликолем или бутиленгликолем с присутствием катализатора переэтерификации, при котором смесь переэтерифицируемых исходных материалов подается в реактор, в котором она последовательно проходит через каналы или трубы реакции и при выходе с этой ступени подается соответственно на тарелку колонны. Там реакционная смесь подвергается массообмену и энергообмену вместе с протекающими ей навстречу испарениями последующих ступеней перед тем, как ее направят в каналы или трубы реакции следующей ступени и, в конце концов, заберут продукт переэтерификации из реактора.
