Versuchsvorschrift

The same procedure as in Example 1 was repeated except that 10.0 g of 1,4-naphthoquinone was added to 200 g of a mixed acid consisting of 83 percent by weight of sulfuric acid, 4 percent by weight of nitric acid and 13 percent by weight of water with maintaining a temperature of 5° to 10°C, to obtain 8.9 g of brown-colored crude 5-nitro-1,4-naphthoquinone of a melting point of 140°C. The D.V.S. of the reaction mixture after reaction was 6.1. The crude product was purified to obtain the similar results with Example 1.
