Procedure

50 G of a crude 1-nitroanthraquinone manufactured according to Example 1 are treated, in accordance with German Offenlegungsschrift (German Published Specification) 2,206,960, with 30 g of sodium sulphite in 400 ml of water. After filtration, washing and drying, 34.6 g of 1-nitroanthraquinone of the composition indicated in Table A are obtained (= 63% of theory, relative to anthraquinone employed).
