    摘要: The invention relates to a method and a device for producing polyesters such as for example polyethylene terephthalate, polypropylene terephthalate and polybutylene terephthalate from precondensates. According to said method, vapors comprising precondensate components that are distributed therein in the form of an aerosol are guided through a polycondensation reactor in which precondensate components condense on the reactor wall and on a separator in an exit chamber of the reactor. The condensates are guided to the unstirred discharge sump and the upper layers of the discharge sump are continuously recirculated into the stirred reactor area thereby subjecting them to reconversion and additional polycondensation.

    摘要: In the continuous production of polyesters, the esterification/transesterification of dicarboxylic acids or esters of the dicarboxylic acids with diols is performed in at least one reaction stage, the prepolycondensation of the esterification/transesterification product is performed under a vacuum in a reaction stage consisting of a vertical tube, and the polycondensation of the prepolycondensation product is performed in at least one reaction stage. To be able to perform the prepolycondensation in a reaction stage, while at the same time increasing the viscosity of the prepolycondensation product and decreasing the process temperatures, the esterification/transesterification product flowing into the prepolycondensation reactor successively traverses in a free movement under limited heating first at least one first reaction zone formed of an annular channel, is then introduced into the radially outer ring duct of at least one second reaction zone formed of an annular channel divided into a plurality of concentric ring ducts, thereafter is successively passed through the ring ducts to the outlet, and is then introduced into a stirred third reaction zone located at the bottom of the vertical tube.

    摘要: In a method for the continuous pre-polycondensation of esterification/transesterification products the stream freely passes from top to bottom in a vertical reaction apparatus through a plurality of attached, heatable, sloped open-above bases, through product overflow channels connected with each other. In order to be able to set a determined, efficient as possible product level in the channels, the esterification/transesterification products are fed though closed, annular-type, concentric annular channels or through parallel channels, wherein a partial quantity of the product stream flowing in the channel is discharged at the product overflows and the remaining product stream is passed via drainage openings.
