Reaction Steps
85 g of 1-nitro-anthraquinone, redissolved in nitrobenzene and reprecipitated (88.2% pure), is heated to 180° C. with 145 ml of water in a 0.7 l stirred autoclave. A solution of 14.6 g of NH4Cl in 240 ml of 25% strength NH3 solution is pumped in over a period of 5 minutes. The mixture is allowed to react for a further hour and cooled and the product is filtered off. After drying, 75.4 g of 86.8% pure 1-amino-anthraquinone=97.4% of theory are obtained.
