This product was made at Leverkusen Plant as follows:

In anenamelled, agitated reaction kettle are placed 2000 liters of nitrobenzene and then are added

190 kilograms 1-amino-5benzoylamino anthraquinone.   240 kilograms 1-benzoylamino-4-chloro anthraquinone.       50 kilograms magnesium oxide.       145 kilograms sodium acetate (kesselsaltz)

This mixture is then agitated and heated to 205-210⁰ in about 5 hours and then cooled back to 180⁰ at which temperature 3.8 kilograms of copper powder are added.

At the end of three hours the condensation is finished and the melt is blown to a Venuleth and there the nitrobenzene is distilled off. The removal of inorganic salts is carried out by boiling the crude, dry ground product in dilute hydrochloric acid 2% in 8000 liters of water in a 10,000 liter brick lined extraction tank after which the crude is filtered off on a brick lined nutsch, washed with hot water, and dried.

Yield = 361 kilograms of plant product dry = 98% of theory.
