실험 절차

A 4-necked 3-L flask, equipped with a mechanical stirrer, a nitrogen inlet, and thermometer, is charged with 83% sulfuric acid (640 g). To this sulfuric acid, phenol (354 g) is added at 20° C. Chloral (200 g) in an additional funnel is added dropwise to the phenolic stirring mixture. The reaction temperature is maintained below 30° C. After the addition, the mixture is allowed to stir at room temperature for 18 hours, before water (640 g) is added. The resulting mixture is filtered and washed with more water to afford 1,1,1-trichloro-2,2-bis(4-hydroxyphenyl)ethane (423 g) as white solids.
