Abstract

The invention relates to a method and to a corresponding device for multi-stage vacuum generation during the production of polyesters or copolyesters by esterifying dicarboxylic acids and diols or by transesterifying dicarboxylic acid esters and diols in a number or reaction stages. The method is characterized by the following steps: 1. The vapors (1) are drawn from a final reactor and directly into a first jet nozzle (2) inside of which they are condensed; 2. The condensed vapors (1), together with a supplied propellant gas (3), form a vapor/operating steam mixture and are guided in a first injection condenser (4) in parallel flow with the injected diol (5); 3. The vapor/operating steam mixture is largely compressed by the injected diol (5) and on the walls of the first injection compressor (4) that are wetted by diol; 4. The polymers discharged from the first injection compressor (4) with the exiting diol (5) are separated out.
