ABSTRACT:
Vanillin is difficult to separate from second organic chemicals produced therewith such as parahydroxybenzaldehyde by conventional distillation or rectification because of the proximity of their boiling points. Vanillin can now be readily separated from such second organic chemicals by azeotropic distillation using as an effective azeotropic distillation agent, dibenzyl ether.
