실험 절차

0.01 mole (1.09 g) of para-amino-phenol and 0.01 mole (1.68 g) of 2-methyl-5-amino-6-nitro phenol are dissolved in 15 cc of ammonia (22° Be) to which have been added 15 cc of water. To this resulting solution maintained at a temperature of about 0° C., there is added, with agitation, 0.02 mole (4.6 g) of ammonium persulfate in 20 cc of water. The agitation is maintained for 30 minutes, after which the indophenol which has precipitated in the form of its ammonium salt is filtered. The thus recovered crude product is treated with water to which has been added acetic acid to obtain the indophenol in its free form. After filtering the indophenol, washing it with water and drying it under a vacuum, there is obtained a product which melts with decomposition above 260° C.
