Abstract

Device and method of realization therein for the preparation of polyesters; in batch, by polycondensation, characterized in that it comprises an envelope comprising means for the introduction of the reagents and means for extracting the polyester obtained with said envelope: - a lower zone provided with means for the introduction of a gas phase, - an upper zone provided with means for the evacuation of a vapor phase, - an intermediate zone between said zones comprising at least one vertical tube heated externally and communicating the lower and upper zones and at least one vertical duct communicating the upper and lower zones, introducing the gas phase in such a way as to allow the circulation of liquid that contains the gas inside the tubes, while circulating through the conduit a liquid that practically does not contain gas.
