실험 절차

Aniline (25 g; 1.39 moles of aniline per mole of p-isopropenyl-o-cresol) was added to 50 g of a mixture of o-cresol and p-isopropenyl-o-cresol (1:1 mole ratio) obtained by the alkali cleavage of 2,2-bis(4'-hydroxy-3'-methylphenyl)-propane. The mixture was stirred at 170° C., and 1.5 g of the catalyst solution prepared in Example 1 (0.0029 mole of catalyst per mole of p-isopropenyl-o-cresol) was added. The reaction was performed for 3 hours. Gas-chromatographic analysis of the resulting reaction mixture showed that 42.7 g (yield 91%) of 2-(4'-hydroxy-3'-methylphenyl)-2-(4'-aminophenyl)-propane having a melting point of 152.5 to 153.5° C. was formed.
