| 摘要 |
The invention relates to a process for the preparation of 2-(hydroxyalkyl)acrylic compounds having the formula <IMAGE> wherein X represents a -CN group, a -COOR3 group, a -COR4 group or a -CONR4R5 group wherein R3 is an alkyl group containing 1-4 C atoms and R4 and R5 independently represent an H atom or R3, and wherein R1 and R2 independently represent an H atom or an alkyl group with 1-4 C atoms or an (hetero) aryl group, or R1 and R2 together represent a cyclic compound with 5-12 C atoms by contacting an acrylic compound H2C=CH-X with a carbonyl compound of the formula <IMAGE> wherein X, R1 and R2 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. |
