실험 절차

It must be described as extremely suprising that the reaction of 1-amino-4-bromo-anthraquinone-2-sulphonic acid with ammonia in water under the reaction conditions employed, under pressure, should take place so uniformly and smoothly to give 1,4-diamino-anthraquinone-2-sulphonic acid, without the formation of significant amounts of 1-amino-4-hydroxy-anthraquinone-2-sulphonic acid, as reported in German Patent Specification No. 1,142,174.
