Abstract

L'invention se rapporte au génie chimique. Elle concerne un procède continu d'estérification directe d'acide téréphtalique par de l'éthylèneglycol, suivi d'une polymérisation sous basse pression dans un appareil de prépolymérisation 30 et dans un appareil de polymérisation finale 46, dans lequel les vapeurs provenant des appareils de polymérisation sont condensées dans des condenseurs à pulverisation 52, 66 pour recueillir du glycol liquide que l'on recycle au réacteur d'estérification 24. Un fonctionnement efficace des condenseurs à des pressions de moins de 60 mm de Hg est obtenu par addition (en 70) d'éthylèneglycol pratiquement anhydre pour réduire la teneur en eau du condensat utilisé dans les pulverisateurs. Utilisation dans la production de poly(téréphtalate d'éthylène) filable à l'état fondu en fils textiles.
