Abstract: The present invention relates to a method for producing a diester of terephthalic acid by reacting terephthalic acid with at least one alcohol. In said method, terephthalic acid is suspended in the alcohol in a dispersion tank, the pre-suspension is conducted from the dispersion tank into a reactor and is reacted in the presence of an esterification catalyst. Reaction water is distilled off with the vapors in the form of an alcohol-water azeotrope, the vapors are at least partially condensed, the condensate is separated into an aqueous phase and an organic phase, the organic phase is dehydrated and the dehydrated organic phase is at least partially conducted into the dispersion tank.

Abstract: The present invention relates to a method for producing a diester of terephthalic acid by reacting terephthalic acid with at least one alcohol. In said method, terephthalic acid is suspended in the alcohol in a dispersion tank, the pre-suspension is conducted from the dispersion tank into a reactor and is reacted in the presence of an esterification catalyst, a reaction suspension is drawn off from a region lying between the upper region and the lower region of the reactor, a first stream of the reaction suspension is returned to the upper region of the reactor and a second stream of the reaction suspension is introduced into the lower region of the reactor, thus intermixing said reaction suspension. The stream that has been drawn off and/or the first stream is/are conducted through a heat exchanger lying outside the reactor and is/are heated. Reaction water is distilled off with the vapours in the form of an alcohol-water azeotrope, the vapours are at least partially condensed, the condensate is separated into an aqueous phase and an organic phase and the organic phase is at least partially returned to the reaction system.
