ABSTRACT:
A method for efficiently recovering a hydroxyaromatic compound from aqueous extract streams of diaryl carbonate reaction mixtures, comprises contacting the aqueous extracts with a suitable solvent, preferably diphenyl carbonate or anisole. The aqueous stream may then be further recycled or reclaimed, and the hydroxyaromatic compound isolated from the solvent for disposal or further use.
