ABSTRACT:
The invention relates to a process for the preparation of 2-(hydroxyalkyl)acrylic compounds having the formula ##STR1## wherein X represents a --CN group, a --COOR.sub.3 group, a --COR.sub.4 group or a --CONR.sub.4 R.sub.5 group wherein R.sub.3 is an alkyl group containing 1-4 C atoms and R.sub.4 and R.sub.5 independently represent an H atom or R.sub.3, and
wherein R.sub.1 and R.sub.2 independently represent an H atom or an alkyl group with 1-4 C atoms or an (hetero) aryl group, or R.sub.1 and R.sub.2 together represent a cyclic compound with 5-12 C atoms
by contacting an acrylic compound H.sub.2 C.dbd.CH--X with a carbonyl compound of the formula ##STR2## wherein X, R.sub.1 and R.sub.2 denote the same as in the above, this being effected in the liquid phase in the presence of a tertiary amine, characterized in that the reaction is carried out at a pressure in excess of 500 bar in excess of 500 bar, advantageously 1,500-18,000 bar.
