Method for producing diesters of terephthalic acid with a dehydration of recirculated alcohol

A process for preparing a terephthalic diester which comprises reacting terephthalic acid with at least one alcohol, wherein

• a) suspending terephthalic acid in the alcohol in a dispersing tank to obtain a preliminary suspension,
• b) passing the preliminary suspension from the dispersing tank into a reactor and converted in the presence of an esterification catalyst,
• c) distilling off water of reaction together with the vapor as alcohol-water azeotrope, the vapor is at least partly condensed, the condensate is separated into an aqueous phase and an organic phase, the organic phase is dewatered and the dewatered organic phase is passed at least partly into the dispersing tank, and the alcohol is selected from the group consisting of linear C8 to C14 monools, branched C8 to C14 monools, cyclic C8 to C14 monools and aromatic monools and
• d) producing the terephthalic diester.
