Procedure

50 parts of 1,5-dinitroanthraquinone are heated in 500 parts of 30% strength oleum for 3 hours at 50° C. 25 parts of boric acid are then added with cooling in the course of 20 minutes, the resulting reaction mixture is then cooled down to 15° to 20° C. and 7 parts of sulphur are added to it. After 6 hours' further stirring at 15° to 20° C. the reaction mixture is worked up as indicated. 25.8 parts of 1-hydroxy-4-amino-8-nitroanthraquinone are obtained.
