실험 절차

A distillation flask equipped with a Vigreux column was charged with 70.0 g. (0.31 mole) of bisphenol A [2,2-bis(p-hydroxyphenyl)propane] and 0.2 g. of sodium hydroxide. The bisphenol A was pyrolyzed under reduced pressure at a bath temperature of 200° to 270° C. Over a period of about 50 minutes and under 10 mm. of pressure (mercury) a distillate of 68.1 g. of a mixture of phenol and isopropenylphenol was obtained.
