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 ML x , 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.

Claim (Index 23):
The method according to  claim 22 , wherein the dehydration of the 3-hydroxypropionic acid ester is conducted in the gas phase.
