Reaction Steps
A glass reactor equipped with a stirrer, reflux condenser, addition funnel, and a device for controlling temperature was charged with 550 grams (5.85 moles) of phenol and 2.75 grams (0.03 mole) of oxalic acid. This mixture was heated to 110° C., and 298.8 grams (3.68 moles) of 37% formalin was slowly added during approximately 60 minutes (3600 s). The reaction mixture was allowed to reflux during the formalin addition, and for about 60 minutes (3600 s) thereafter. A vacuum was then applied, and the excess phenol and water were removed by vacuum distillation at a final temperature of 180° C.
