Abstract

1,214,256. Method of preparation of anthraquinone 1,5-disulphonic acid or alkali metal salts. VYZKUMNY USTAV ORGANICKYCH SYNTEZ RYBITVI PARDUBICE. 4 Sept., 1969, No. 43747/69. Heading C2C. Anthraquinone 1,5-disulphonic acid is prepared by heating anthraquinone 1,8-disulphonic acid or an alkali metal salt thereof with anhydrous sulphuric acid in the presence of a mercuric salt as catalyst, e.g. mercury sulphate. The corresponding alkali metal salt may be obtained by diluting the reaction product and adding an alkali metal salt.
