Reaction Conditions

Reaction Steps

Ten grams of aniline was added to a mixture consisting of 13.0 g of phenol, 3.4 g of p-isopropenyl phenol monomer, 8.5 g of a linear dimer of p-isopropenyl phenol, 1.1 g of a linear trimer of p-isopropenyl phenol and 0.8 g of a linear tetramer and higher polymers of p-isopropenyl phenol (1.05 mole of aniline per mole of the p-isopropenyl phenol monomeric unit). The mixture was stirred at 180° C. Then, 0.2 g of 10% hydrochloric acid (0.0053 mole per mole of the p-isopropenyl phenol monomeric unit) was added, and the reaction was performed for 2 hours. Gas-chromatographic analysis of the reaction mixture showed that 0.38 g of bisphenol A and 21.8 g (yield 93%) of 2-(4'-hydroxyphenyl)-2-(4'-aminophenyl)-propane were formed.
