Abstract

331,537. Loveluck, R. J., Beckett, E. G., Thomas, J., and Scottish Dyes, Ltd. Dec. 28, 1928. Anthraquinone derivatives.-The products obtained by oxidizing an o-amino-#-sulphonic acid of anthraquinone with potassium persulphate in sulphuric acid are treated with a halogenating agent, for example sodium chlorate and hydrochloric acid, whereby the sulphonic acid group is replaced by halogen. Reduction of these halogenated derivatives by means of sodium hydrosulphide, or hydrogen sulphide and ammonia or neutral hydrosulphite yields the corresponding o-aminohalogen derivatives. By the persulphate oxidation 1-amino-2-sulpho-, and 2- amino-3-sulphoanthraquinone are converted to 1- nitroso-2-sulpho- and 2-nitro-3-sulpho-anthraquinone respectively, and the latter by the treatment with sodium chlorate and hydrochloric acid are converted to 1-nitroso-2-chlor- and 2-nitro-3- chloranthraquinone respectively. In example (1) 1-amino-2-sulphoanthraquinone is converted by the above processes to 1-nitroso-2-chloranthraquinone and the latter reduced with sodium hydrosulphide to 1-amino-2-chloranthraquinone; the product is purified by dissolving in strong sulphuric acid, diluting the solution when the sulphate precipitates out, filtering and decomposing the sulphate with water; (2) 2-amino-3- sulphoanthraquinone is converted by the above means to 2-nitro-3-chloranthraquinone and reduced with sodium hydrosulphide to 2-amino-3- chloranthraquinone. These products may also be purified as described in Specification 268,537.
