    Abstract: A process for preparing solketal acrylate by transesterifying ethyl acrylate with solketal, comprising the steps of: (i) reacting ethyl acrylate with solketal in the presence of a catalyst comprising titanium(IV) or zirconium(IV) and a stabilizer in the presence of ethyl acrylate as azeotropic agent which forms an azeotrope with ethanol, (ii) continuously distilling off and condensing an azeotrope containing ethyl acrylate and ethanol by means of a distillation column operated under reflux conditions, wherein steps (i) and (ii) are conducted simultaneously until a solketal conversion of ≥ 95% is reached, characterized in that step (ii) is carried out by diluting the condensed azeotrope with additional ethyl acrylate and using this mixture as a reflux to the distillation column.
