ABSTRACT:
An aromatic compound is hydroxylated by reacting the aromatic compound in an aqueous solvent with a triiodide salt to form a reaction mixture containing the corresponding iodoaromatic compound. The mixture is reacted, without separating the iodoaromatic compound, with a hydroxylating agent to form the corresponding hydroxy aromatic compound. The iodide salt, formed as a by-product of the reaction, is then separated for reuse in the process.
