摘要： A process has been invented for the preparation of 1,5-dichloroanthraquinone which comprises reacting 1,5-dichloroanthraquinone with chlorine in the presence of at least 50% by weight of liquid phthalic anhydride, relative to the weight of 1,5-dinitroanthraquinone employed. The 1,5-dichloroanthraquinone is known to be a valuable starting material for the preparation of various dyestuffs.

摘要： A process has been developed for the mononitration of anthraquinone to 1-nitroanthraquinone with nitric acid/sulphuric acid mixtures wherein anthraquinone is nitrated in a nitric acid/sulphuric acid mixture, in which the weight ratio of nitric acid to sulphuric acid is about 1:1 to about 2:1, in which the weight ratio of sulphuric acid to anthraquinone is about 0.5:1 to about 1:1 and in which the weight ratio of sulphuric acid to water is about 2.5:1 to about 5.5:1, the weight ratios relating to the sum of the materials employed, at temperatures in the range from about 45.degree. to 70.degree. C. until the anthraquinone content is less than 3% by weight, relative to the sum of the anthraquinone compounds.
