Versuchsvorschrift

100 g of 1,6-dinitro-anthraquinone and 84 g of p-anisidine are stirred in 300 ml of nitrobenzene at 150° C until no further starting material is detectable in a sample. The mixture is now distilled to dryness in a Venuleth apparatus under a vacuum of 5 mm and the finely ground residue is thoroughly stirred with dilute sulphuric acid, filtered off, washed until neutral and dried. 125 g of 1-p-anisidino-6-nitro-anthraquinone are obtained.
