Is it possible to "undo" the ferric/phenolate complex?
Adding ferric chloride to phenols usually creates a precipitate.
Is there a simple way to "undo" the ferric/phenolate complex? It would be a nice way to purify phenols, or even separate different phenols.

you should be able to distill it

How about adding NaOH, filtering the FeOH2 (squeeze hard, or boil to form denser forms) and keep the soluble Na-phenolate?

Also a good idea...
Humm, maybe the precipitate I got in previous experiments with phenolates had a lot of FeOH2 in them since I added NaOH (carelessly) to phenols to
obtain the phenolate. Maybe the phenol/ferric complex does not usually precipitate like I thought. Separation may not be so simple without a
chromatography column.

Try adding a solution of EDTA, and wait a while. The colored complex should disappear. Then distill (or extract) the phenol out (it distills with
water). Good luck getting your phenol from the water, though.
