Process for the preparation of hydroxybenzaldehydes by hydrocarbonylation |
| abstract |
The present invention relates to a process for the preparation of hydroxybenzaldehydes by hydrocarbonylation of the corresponding halophenols.n n n More specifically, it is a process for the preparation of hydroxybenzaldehydes by reacting a halophenol with a carbon monoxide / hydrogen mixture, in the presence of a tertiary amine, of a catalyst based on a noble metal and of a phosphine.n n n The process notably makes it possible to prepare vanillin from 4-bromo-2-methoxy-phenol. |
