Abstract: A process for preparing isosorbide ethoxylate di(meth)acrylate by transesterifying alkyl (meth)acrylate with isosorbide ethoxylate, comprising the steps of: (i) ethoxylating isosorbide to give isosorbide ethoxylate, (ii) reacting alkyl (meth)acrylate with isosorbide ethoxylate in the presence of potassium phosphate as catalyst and a stabilizer and in the presence of an azeotroping agent which forms an azeotrope with the alcohol bound in the alkyl (meth)acrylate, (iii) continuously distilling off the azeotrope of azeotroping agent and alcohol, wherein steps (ii) and (iii) are conducted simultaneously until the isosorbide ethoxylate has been essentially fully converted, (iv) removing the catalyst from the product mixture comprising isosorbide ethoxylate di(meth)acrylate, (v) distilling unconverted alkyl (meth)acrylate and azeotroping agent out of the product mixture.

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.

Abstract: The invention relates to a method for producing isosorbide dimethacrylate by the transesterification of alkyl(meth)acrylate with isosorbide, comprising the following steps: (i) permitting alkyl(meth)acrylate to react with isosorbide in the presence of a catalyst containing titanium (IV) or zirconium (IV) and of a stabilizer in the presence of an entrainer, forming an azeotrope with the alcohol bonded in the alkyl(meth)alcylate; (ii) continuously distilling off the azeotrope that consists of entrainer and alcohol, steps (i) and (ii) being carried out simultaneously until isosorbide is substantially completely converted; (iii) adding water to the product mixture obtained in steps (i) and (ii) and containing isosorbide dimethacrylate, and separating the hydrolysate from the catalyst containing titanium (IV) or zirconium (IV); (iv) distilling off non-converted alkyl(meth)acrylate and entrainer from the product mixture; and (v) distilling off water from the product mixture, wherein step (iv) can also be carried out before step (iii), and the steps (iv) and (v) can also be carried out in a distillation step.

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 obtained, a stream of the reaction suspension is drawn off, is conducted through a heat exchanger lying outside the reactor and is heated and the heated reaction suspension is returned to the reactor. 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 reactor.
