      Additional patent to main patent No. 244053. Process for the production of a trisazo carbate. The subject of the present additional patent is a process for the production of a trisazo dye, characterized in that the dianotated disazo dye of the formula.

    
EMI0001.0007
    is combined with the learning triazine condensation product of 1 mol of cyanuric chloride, 1 mol of 2-amino-5-oxynaphthalene-7-sulfonic acid, 1 mol of 1-aminobenzene-3-sulfonic acid and 1 mol of 1-aminobenzene in an alkaline solution.



  The new dye forms a dark powder that dyes cotton in a weakly alkaline bath in the presence of copper sulfate and tartrate of sodium in washfast gray tones.



  <I> Example: </I> 15.3 parts by weight of 1-amino-3-carboxy-4-oxybenzene are diazotized in the customary manner and, in the presence of sodium acetate, with 22.3 parts by weight of 1-naphthyla .min-7-sulphonic acid, which was dissolved as the sodium salt in 200 parts by weight of water, kup pelt at 0.

   The monoazo dye which separates out is then brought into solution with aqueous sodium hydroxide solution, 6.9 parts by weight of sodium nitrite in 25% aqueous solution are added and the mixture is concentrated to a mixture of 200 parts by weight of ice water and 50 parts by weight . Allowed hydrochloric acid to run in.

   When the dianotation, which is carried out at 0-5, is complete, the diazo compound deposited by means of sodium chloride is filtered off with suction and treated with a further 22.3 parts by weight of 1-naphthylamine-7-sulfonic acid, which is dissolved as the sodium salt in 200% by weight. Parts of water were dissolved, combined.

   During the coupling, 20 parts by weight of sodium acetate are sprinkled in and the product is separated out after some time with common salt. It is brought into solution with a little sodium hydroxide solution, with 6,

  9 parts by weight of sodium nitrite in 25% solution are added and this mixture with a mixture of 200 parts by weight of ice water and 50 parts by weight of conc. Hydrochloric acid further dianotized at 1.5. The deposited diazo compound is then mixed with 58 parts by weight of the ternary prepared in a known manner,

  Ren triazine condensation product from 1st mole of cyanuric chloride, 1 mole of 2-amino-5-oxynaphthalene-7-sulfonic acid, 1 mole of 1-aminobenzene-3-sulfonic acid and 1 mole of 1-aminobenzene combined in sol-alkaline solution. After the coupling has ended, the dye is deposited and dried.
