    IPC: C09J4/00

    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.
