  Process for the production of a green substantive dye of the anthraquinone series The subject of the present patent is a process for the production of a green substantive dye of the anthraquinone series, which consists in adding 1 mol of 7th-amino-4-W-amino) -phenylaminoanthra- cliinon-2,6-disulfonic acid and 1 mole of the 4-amino-1 diazotized by coupling,

  1'-azoben-zene-3,4'-disulfonic acid with 1-amino-3-methyl-benzene, subsequent condensation of the coupling product with a 4-nitrobenzene-1-carboxylic acid halide and reducing the nitro group to the amino group obtainable aminodisazo compound with 1 mol of a di - lialogenids, preferably dichloride,

      the fumaric acid condenses.



  <I> Example: </I> 5.4 parts of 1-amino-4 - (4'-amino) -phenyjaminoanthraclinone-2,6-disulfonic acid are dissolved in 400 parts of water in the form of its sodium salt and 6.95 parts of the also present in the form of the sodium salt, by coupling diazotized 4-amino-1,1'-azobenzene-3,4'-disulfonic acid with 1-amino-3-methylbenzene,

      subsequent condensation of the coupling product with a 4-nitrobenzene-1-carboxylic acid halide and reduction of the nitro group to the amino group obtainable aminodisazo compound. The solution is cooled to 0 to 4 and 11 parts by volume of a molar solution of fumaric acid dichloride in carbon tetrachloride are added dropwise to it from a dropping funnel over the course of 45 minutes, with thorough stirring. The resulting hydrogen chloride is 8 parts by volume 10% <RTI

   ID = "0001.0052"> Sodium hydroxide solution neutralized in such a way that the pH of the reaction mixture remains at 7 to 8. After the condensation has ended, the carbon tetrachloride is distilled off, 36 parts of sodium chloride are added to the mass, the reaction product which has precipitated is suction filtered off at 20 ° and it is dried. The new dye dyes cotton and fibers made of regenerated cellulose from an aqueous solution in yellow-green shades that are washfast and lightfast.
