An apparatus as described in Example 1 was charged with diphenyl ether (0.1 mol), phenol (0.1 mol) and sulfuric acid (0.5 g). The reagents were heated to 80° C. and stirring started. Formaldehyde (13 mL, 0.17 mol) was added dropwise resulting in the rapid formation of a solid product. After the addition was complete, the mixture was heated under reflux for 1 hour. The resulting product was a solid, insoluble mass.
