4-Aminophenol → Phenolindophenol

참여 물질

반응 단계

0.01 mole (1.09 g) of paraaminophenol is dissolved in 100 cm3 of a 0.1 N NaOH solution. A second solution of 0.01 mole (1.23 g) of 5-amino-2-methyl phenol in 100 cm3 of a 0.1N NaOH solution is also prepared. The two solutions are then mixed and air is bubbled in the resulting mixture for about 5 hours at ambient temperature. The reaction medium is then acidified with sufficient HCl to pH 5 to produce 1.2 g of said indophenol which is then filtered off and which, after recrystallization from a dimethylformamide-water mixture, melts at 215°.
