Description

  

      Verfahren    zur Herstellung eines neuen Zwischenproduktes.    Es wurde gefunden, dass man ein neues  Zwischenprodukt, das sekundäre     Kondensa-          tionsprodukt    von einem     Mol.        Cya.nurchlorid     mit einem     1M1.        1.8-Aminonaphthol-3.6-di-          sulfosäure    und einem     Mol.        1-Aminoben7,ol-2-          oxy-5-sulfo-3-karbonsäure,    erhält, wenn man  auf ein hol.

       Cyanurchlorid    in beliebiger Rei  henfolge ein     Mol.        1.8-Aminonaphthol-3.6-          disulfosäure    und ein     Mol.        1-Amino-2-oxy-5-          sulfo-3-l:arbonsäure    einwirken lässt.  



  Diese Kondensation wird durch     Zusam-          menrühren    der Komponenten in einem geeig  neten     Verdünnungsmittel    durchgeführt, und  es wurde gefunden, dass als solches Wasser  in überraschender Weise sehr gut geeignet  ist.

   Das sekundäre     Kondensationsprodukt    aus  einem     Mol.        Cyanurchlorid,    einem     Mol.        1.8-          Aminonaphthol-3.6-disulfosä,ure    und einem       Mol.    1-     Amiobeii7ol-2-oxy-5-sulfo-3-karboiz-          säure    bildet ein in Wasser leicht lösliches,  farbloses, kristallinischer Pulver. Es enthält  noch ein reaktionsfähiges Chloratom und  stellt ein wertvolles     Ausgangsmaterial    zur  Herstellung von Farbstoffen dar.

           13eisiel:     31,9 Teile     1.8-Aminonaphthol-3.6-di-          sulfosäure    werden in 500 Teilen Wasser un  ter Zusatz von     13,3    Teilen 30      ioiger    Natron  lauge gelöst, mit<B>18,5</B> Teilen     Cyanurchlorid          versetzt    und gerührt, bis die     Komponenten     verschwunden sind. Die so erhaltene saure  Lösung wird sehr vorsichtig fast genau neu  tralisiert und hierauf mit einer Lösung aus  24 Teilen     1.8-Aminonaphthol-3.6-disulfo-          säure    in 200 Teilen Wasser und 26,6 Teilen  30     %iger    Natronlauge versetzt.

   Man rührt,  bis die     1-Aminobenzol-2-oxy-5-sulfo-3-kar-          bonsäure    fast verschwunden ist, und isoliert  das sekundäre Kondensationsprodukt aus  einem     Mol.        Cyanurchlorid,    einem     Mol.    1.8  A.minonaphthol-3 -     6-disulfosäure    und einem       Mol.        1-Amino        enzol-2-oxy-,5-sulifo-3-karbon-          säure    durch     Aussalzen.  



      Process for the production of a new intermediate product. It has been found that a new intermediate, the secondary condensation product of one mole of Cya.nurchlorid with a 1M1. 1,8-aminonaphthol-3,6-disulfonic acid and one mole of 1-aminoben7, ol-2-oxy-5-sulfo-3-carboxylic acid, is obtained when one is on a hol.

       Cyanuric chloride in any order one mole of 1.8-aminonaphthol-3.6-disulfonic acid and one mole of 1-amino-2-oxy-5-sulfo-3-l: carboxylic acid can act.



  This condensation is carried out by stirring the components together in a suitable diluent, and it has been found that, surprisingly, water is very suitable as such.

   The secondary condensation product of one mole of cyanuric chloride, one mole of 1.8-aminonaphthol-3,6-disulfonic acid and one mole of 1-aminonaphthol-2-oxy-5-sulfo-3-carboic acid forms a colorless acid which is readily soluble in water , crystalline powder. It still contains a reactive chlorine atom and is a valuable starting material for the production of dyes.

           13eisiel: 31.9 parts of 1,8-aminonaphthol-3,6-disulphonic acid are dissolved in 500 parts of water with the addition of 13.3 parts of 30% sodium hydroxide solution, mixed with 18.5 parts of cyanuric chloride and stirred until the components are gone. The acidic solution thus obtained is very carefully neutralized almost exactly and a solution of 24 parts of 1,8-aminonaphthol-3,6-disulfonic acid in 200 parts of water and 26.6 parts of 30% sodium hydroxide solution is then added.

   The mixture is stirred until the 1-aminobenzene-2-oxy-5-sulfo-3-carboxylic acid has almost disappeared, and the secondary condensation product is isolated from one mole of cyanuric chloride and one mole of 1.8 A.minonaphthol-3-6-disulfonic acid and one mole of 1-amino enzene-2-oxy, 5-sulpho-3-carbonic acid by salting out.
