ABSTRACT:
A vinyl compound having a hydroxy group of the formula (1) ##STR1## wherein R is a hydrogen atom or an organic residue, X is a --CN group, a --COR.sub.0 group or a --COOR.sub.0 group and R.sub.0 is a hydrogen atom or an organic residue, is prepared by reacting a vinyl compound of the formula (2) ##STR2## wherein X is a --CN group, a --COR.sub.0 group or a --COOR.sub.0 group and R.sub.0 is a hydrogen atom or an organic residue, with an aldehyde series compound in the presence of a tertiary amine compound, and water in a sufficient amount for forming an aqueous phase upon the completion of the reaction. In this method, since the aqueous phase is formed upon the completion of the reaction, the organic phase including the vinyl compound having a hydroxy group and the aqueous phase including the tertiary amine compound can be easily separated.
