Conditions

Temperature
50 °C

Procedure

1,000 g of anthraquinone and 500 ml of hydrogen fluoride (90 percent strength) are initially introduced into a 4 liter Venuleth vessel and stirred for 15 minutes. A mixture of 500 ml of hydrogen fluoride (90 percent strength) and 240 ml of nitric acid (98 percent strength) is added at room temperature over the course of 5 minutes. The bath temperature of the Venuleth vessel is then raised to 50°C and the mixture is stirred at this temperature for 4 hours. Working up takes place as in Example 6. 1,200 g of nitro-anthraquinone of the following composition are obtained:
