ABSTRACT:
A process and an apparatus for the production of high molecular weight linear polyester is proposed, in which a pumpable material is produced in particular terephthalic acid and an alkaline diol which is esterified in a two or multi-stage reactor arrangement and is subsequently condensed in vacuo in at least one vacuum reactor. The waste heat of the esterification reactor arrangement is used for producing the vacuum in the vacuum reactors. The water for condensing the steam is also obtained from the process steam.
