    Abstract: The invention relates to a method for producing Heonon(meth)acrylate via the transesterification of alkyl(meth)acrylate with Heonon, comprising the following steps: (i) permitting alkyl(meth)acrylate to react with Heonon in the presence of a catalyst containing titanium (IV) or zirconium (IV) and a stabiliser in the presence of an entrainer, forming an azeotrope with the alcohol bonded in the alkyl(meth)alcylate; (ii) continuous distilling off of the azeotrope from the entrainer and alcohol, wherein steps (i) and (ii) are carried out simultaneously, until heonon is substantially completely converted; (iii) adding water to the product mixture obtained in steps (i) and (ii) and containing heonon(meth)acrylate, and separating the hydrolysate from the catalyst containing titanium (IV) or zirconium (IV) by means of filtration; (iv) distilling off of non-converted alkyl(meth)acrylate and entrainer from the product mixture; (v) distilling off of 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, characterised in that the steps (i) and (ii) are carried out in the presence of an inorganic or organic acid.

    Abstract translation: 本发明涉及一种通过（甲基）丙烯酸烷基酯与Heonon的酯基转移作用生产（甲基）丙烯酸蒽醌的方法，其包括以下步骤：（i）允许（甲基）丙烯酸烷基酯与Heonon在含有 在夹带剂存在下与钛（IV）或锆（IV）和稳定剂接触，与在（甲基）丙烯酸烷基酯中键合的醇形成共沸物; （ii）从共沸剂和醇中连续蒸馏共沸物，其中步骤（i）和（ii）同时进行，直到heonon基本完全转化; （iii）向步骤（i）和（ii）中获得的产物混合物中加入水并且包含（甲基）丙烯酸壬烯酯，并且通过过滤将水解产物与含钛（IV）或锆（IV）的催化剂分离; （iv）从产物混合物中蒸馏掉未转化的（甲基）丙烯酸烷基酯和夹带剂; （v）从产物混合物中蒸馏除去水，其中步骤（iv）也可以在步骤（iii）之前进行，步骤（iv）和（v）也可以在蒸馏步骤中进行，其特征在于 步骤（i）和（ii）在无机酸或有机酸存在下进行。

    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.
