FIELD: technological processes.
SUBSTANCE: invention is related to method for production of polyester with application of tubular reactor of etherification, both in new and existing (renovated) plants. Method is described for production of polyester with application of tubular reactor. Method includes etherification of liquid reagent in tubular reactor with production and further initiation of liquid reaction mixture and side gaseous product via part of tubular reactor with addition of oligomer.
EFFECT: production of polyester with conversion from 51,9% to 94,2%.
