Abstract: The invention relates to a method for producing isosorbide ethoxylate dimethacrylate by the transesterification of alkyl(meth)acrylate with isosorbide ethoxylate, comprising the following steps: (i) ethoxylating isosorbide to isosorbide ethoxylate; (ii) permitting alkyl(meth)acrylate to react with isosorbide ethoxylate in the presence of potassium phosphate as a catalyst and of a stabilizer and in the presence of an entrainer, forming an azeotrope with the alcohol bonded in the alkyl(meth)alcylate; (iii) continuously distilling off the azeotrope that consists of entrainer and alcohol, steps (ii) and (iii) being carried out simultaneously until isosorbide ethoxylate is substantially completely converted; (iv) separating the catalyst from the isosorbide ethoxylate dimethacrylate-containing product mixture; and (v) distilling off non-converted alkyl(meth)acrylate and entrainer from the product mixture.

Abstract: The invention relates to 3-hydroxypropionic acid esters, obtained by conversion of ethylene oxide with carbon monoxide in the presence of a cobalt catalyst, wherein poly-3-hydroxypropionate is obtained; and transesterification of the poly-3-hydroxypropionate with an alcohol in the presence of a transeseterification catalyst, wherein the 3-hydroxypropionic acid esters are obtained. The transesterification catalyst is a compound of the formula MLx, wherein M stands for a metal of the 2nd, 3rd, or 4th main group or the 3rd to 8th secondary group of the periodic system of the elements, L stands for a ligand, which directly bonds to an M via a C, an O, a P, an S and/or an N atom, and x is a whole number from 2 to 6.
