A 250-mL 3-neck flask equipped with a mechanical stirrer and an addition port was charged with diphenyl ether (34 gm, 0.2 mol), acetic acid (35 mL) containing sulfuric acid (5 mL), and aqueous formaldehyde (37% solution, 46 mL, 0.61 mol). The flask was placed in a 100° C. oil bath and rapid mixing was started. After the reaction between the diphenyl ether and formaldehyde had proceeded for 24 hours phenol (40 mL, 0.46 mol) was added in uniform portions over a 15-minute period.
