In a process of producing polyethylene terephthalate by esterification of terephthalic acid with ethylene glycol and polycondensation, the vapors formed are rectified, the liquid phase is recirculated to the process, and the lower-boiling components are condensed. To obtain an almost completely stripped condensate, condensate is circulated and stripped the same with air, and the exhaust air is subjected to a catalytic oxidation.
