55 °C

Into a 250-millimiter 3-necked round-bottomed flask was charged a mixture of 11.6 grams (0.20 mole) of acetone, 75 grams (0.80 mole) of phenol, 22 grams (0.20 mole) of chlorotrimethyl silane, and 0.10 gram of butanethiol. The resulting mixture was stirred mechanically and heated at 55° C. under a nitrogen atmosphere for 3 hours. On completion of the reaction, the reaction mixture was cooled to room temperature and filtered. The solid product resulting was slurried up in chlorobenzene, filtered and washed twice with chlorobenzene. Purification by recrystallization from methanol and water afforded bisphenol A with a purity of 99.5 percent in a 83 percent yield.
