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 and the organic phase is conducted over a column in which at least part of the vapors is conducted in a counter-current to the organic phase, and the organic phase is collected in the lower region of the column and is at least partially conducted into the dispersion tank.

Abstract: The invention relates to a method for producing carboxylic acid esters by reacting carboxylic acids and/or carboxylic acid anhydrides with at least one alcohol, selected from alkanoles with at least 5 carbon atoms, cycloalkanoles and alkoxyalkanoles, in the presence of an acid esterification catalyst. The invention also relates to the use of the thus obtained carboxylic acid ester as a plasticizer or in a plasticiser composition for thermoplastic polymers and elastomers.

Abstract: A process for preparing isosorbide di(meth)acrylate by transesterifying alkyl (meth)acrylate with isosorbide, comprising the steps of: (i) reacting alkyl (meth)acrylate with isosorbide in the presence of a catalyst comprising titanium(IV) or zirconium(IV) and a stabilizer in the presence of an azeotroping agent which forms an azeotrope with the alcohol bound in the alkyl (meth)acrylate, (ii) continuously distilling off the azeotrope of azeotroping agent and alcohol, wherein steps (i) and (ii) are conducted simultaneously until the isosorbide has been essentially fully converted, (iii) adding water to the product mixture which comprises isosorbide (meth)acrylate and is obtained in steps (i) and (ii) and removing the hydrolyzate of the catalyst comprising titanium(IV) or zirconium(IV), (iv) distilling unconverted alkyl (meth)acrylate and azeotroping agent out of the product mixture, (v) distilling off water from the product mixture, wherein step (iv) can also be conducted before step (iii) and steps (iv) and (v) can also be conducted in one distillation step.
