<p>A vinyl compound with hydroxy group of the general formula (1) <CHEM> wherein R is a hydrogen atom or an organic residue, X is a -CN group, a -COR0 group or a -COOR0 group and R0 is a hydrogen atom or an organic residue, is prepared by reacting a vinyl compound of the general formula (2) <CHEM> wherein X is a -CN group, a -COR0 group or a -COOR0 group and R0 is a hydrogen atom or an organic residue, is reacted 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 reaction. This method offers a higher reaction rate and a shorter reaction time compared with conventional methods. Moreover, the method enables an industrial preparation of the vinyl compound with hydroxy group in high yield and selectivity at low cost. In this method, since the aqueous phase is formed upon the completion of the reaction, the organic phase including the vinyl compound with hydroxy group and the aqueous phase including the tertiary amine compound can be easily separated.</p> |
