反応手順
A solution of 5.0 grams (0.011 mole) of 1,2-bis(3,5-di-t-butyl-4-hydroxyphenyl)ethane dissolved in 30 milliliters of tetralin containing 0.2 gram (0.0012 mole) of p-toluensulfonic acid was heated to reflux for a total of 3 hours. The reaction mixture was cooled and poured into 50 milliliters of water. The precipitated solid was collected by suction filtration and recrystallized from ethanol to yield 2.3 grams (97 percent) of bisphenol E, melting point 199°-200° C.
