Abstract

1480200 Dinitroanthraquinones NIPPON KAYAKU KK 20 May 1975 [24 May 1974 (2)] 21635/75 Heading C2C [Also in Division C4] A mixture of 1,6- and 1,7-dinitroanthraquinones (containing the 1,5- and 1,8-dinitro compounds as impurities) is obtained by nitrating anthraquinone with nitric acid, cooling to precipitate 1,5- and 1,8-dinitroanthraquinone, filtering to remove the 1,5- and 1,8-dinitro compounds, stirring and cooling the filtrate and adding water thereto to precipitate the product.
