  A method for preparing a metal salt of a hydroxy-substituted aromatic compound is described. The method comprises contacting in an aqueous medium at least one hydroxy-substituted aromatic compound with a base comprising a metal cation to provide a mixture comprising water and a metal salt of said hydroxy-substituted aromatic compound. The aqueous metal salt is then contacted with a substantially water-immiscible solvent at a temperature greater than the boiling point of water at the prevailing pressure to provide a slurry comprising the metal salt of the hydroxy-substituted aromatic compound and a vapor stream comprising the water-immiscible solvent and water. The components of the vapor stream are separated using a vapor handling system comprising a partial reflux condenser to provide a water-rich component and a water immiscible solvent-rich component.
