Abstract

510,936. Aminoanthraquinones. SOC. RHODIACETA. Dec. 2, 1938, No. 35180. Convention date, Dec. 24, 1937. [Class 2 (iii)] 1. 4. 5. 8 - Tetraminoanthraquinone is prepared by reacting 1.4.5.8-tetrachloranthraquinone with p-toluenesulphonamide and hydrolysing the condensation product thus obtained. In an example, anthraquinone is treated with chlorine in sulphuric acid containing a little iodine to give 1.4.5.8.-tetrachloranthraquinone, which is reacted with p-toluenesulphonamide in nitrobenzene in presence of copper powder, copper acetate and potassium carbonate to give a product which is hydrolysed by sulphuric acid to give the sulphate of 1.4.5.8-tetraminoanthraquinone. The free base may be dried in the pure state or mixed with a dispersing agent and dried.
