Description

  

  Verfahren zur Herstellung eines neuen     Zwischenproduktes    der     Teerfarbenindustrie.       Es wurde gefunden, dass man ein neues  Zwischenprodukt, .das     primäre        Kondensations-          pxo:dukt    von     einem        Mol.        Cyanurchlowid    mit  einem     Mol.        1,4-Phenylendiamin-3-sulfosäure     .erhält, wenn     :m.an.auf    ein     Mol.        Cyanurchlorid     ein     Mol.        1,4-Phenylendiamin-3-sulfosäure    ein  wirken 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     primäre        Kandensati.onsprodukt    aus     einem.          Mol.        Cyanurchlorid,    mit einem     M:ol.        1,4-Ph-e-          nylendiamän-3-sul.fosäure    bildet ein in Was  ser leicht     lösliches,    fast farbloses, kristallini  sches Pulver.

   Es enthält     noch    zwei reaktions  fähige Chloratome und stellt ein wertvolles  Ausgangsmaterial zur Herstellung von Farb  stoTfen dar.  



       Beispiel:     Eine feine     Suspension    von 18,5 Teilen       Cyanurchlorid    in 500 Teilen     Wasser        wird     unter Rühren     vo,rsiehtig    und bei niedriger  Temperatur mit einer Lösung von 1.8,8 Tei  len     1,4-Phenylendiamin-3-sulfosäure    und 5,3    Teilen Soda in 100 Teilen     ZVasser    versetzt.

    Sobald -das     Cyanurchlorid        verschwunden    ist,       wird,das        als    heller Niederschlag :ausgefallene       primäre        Kondensationsprodukt    von     einem          Mol.        Cyanurchlorid    und einem     Mol.        1,4-Phe-          nylendiamin-2-sulfosäure    filtriert und ge  trocknet.



  Process for the production of a new intermediate product in the tar color industry. It has been found that a new intermediate product, the primary condensation product, is obtained from one mole of cyanuric chloride with one mole of 1,4-phenylenediamine-3-sulfonic acid if: with one mole of cyanuric chloride one mole of 1,4-phenylenediamine-3-sulfonic 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 primary product of Kandensati. From one. Mol. Cyanuric chloride, with one m: ol. 1,4-Ph-enylenediamene-3-sulphonic acid forms an almost colorless, crystalline powder that is easily soluble in water.

   It still contains two reactive chlorine atoms and is a valuable starting material for the manufacture of dyes.



       Example: A fine suspension of 18.5 parts of cyanuric chloride in 500 parts of water is stirred carefully and at low temperature with a solution of 1.8.8 parts of 1,4-phenylenediamine-3-sulfonic acid and 5.3 parts of soda in 100 parts of ZVasser added.

    As soon as the cyanuric chloride has disappeared, the primary condensation product of one mole of cyanuric chloride and one mole of 1,4-phenylenediamine-2-sulfonic acid which has precipitated out as a pale precipitate is filtered and dried.
