4-Hydroxybenzaldehyde → Salicylaldehyde

Participants

Reaction Steps

The phenol aldehyde mixture is in a form combined with sodium. It is neutralized and acidified to a pH of 5. Thereupon the salicylaldehyde is recovered by the conventional carrier vapor distillation of the aqueous phases (following methanol recovery). A yield of 32% (3.9 g) of salicylaldehyde and of 27% (3.2 g) in p-hydroxybenzaldehyde relative to the initial phenol are obtained.
