Abstract: A process for preparing acrylic acid from ethylene oxide and carbon monoxide, in which ethylene oxide is carbonylated in an aprotic solvent with carbon monoxide in the presence of a cobalt catalyst system to give poly-3-hydroxypropionate, the cobalt content in the poly-3-hydroxypropionate formed is reduced with the aid of water and/or an aqueous solution as a precipitation and/or wash liquid, and the poly-3-hydroxypropionate is subsequently split by thermolysis to give acrylic acid.

Abstract: 3-Hydroxypropionic acid esters are obtained by reacting 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 transesterification catalyst, wherein the 3-hydroxypropionic acid ester is obtained. The transesterification catalyst is a compound of the formula MLx, where M is a metal of main groups 2, 3 or 4 or transition groups 3 to 8 of the Periodic Table of the Elements, L is a ligand which is bonded directly to M via a C, an O, a P, an S and/or an N atom, and x is an integer from 2 to 6.
