Description

  

  Verfahren zur Herstellung eines neuen Zwischenproduktes.    Es wurde gefunden, dass man ein neues  Zwischenprodukt, das sekundäre Kondensa  tionsprodukt von einem Mol. Cyanurchlorid  mit einem Mol. 1. 8-Aminonaphthol-3 .     6-di-          sulfosäure    und einem Mol. Dimethylamin,  erhält, wenn man auf ein Mol.     Cyanur-          chlorid    in beliebiger Reihenfolge ein Mol.  1.8-A.minonaphthol-3.6-disulfosäure und ein  Mol. Dimethylamin 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-disulfosäure    und einem  Hol. Dimethylamin bildet ein in Wasser  leicht lösliches, farbloses, kristallinisches  Pulver. Es enthält noch ein reaktionsfähiges  Chloratom und stellt ein wertvolles Aus  gangsmaterial zur Herstellung von Farb  stoffen dar.

      Beispiel:  31,9 Teile     1.8-Aminonaphthol-3.6-di-          sulfosäure    werden in 500 Teilen Wasser  unter Zusatz von 13,3 Teilen 30 %iger     Na-          tranlauge    gelöst, mit 18,5 Teilen     Cyanur-          chlorid    versetzt und gerührt, bis die Kom  ponenten verschwunden sind. Die so erhal  tene saure Lösung wird sehr vorsichtig fast  genau neutralisiert und hierauf nach Zusatz  von 30 Teilen kristallisiertem Natriumacetat  mit einer Lösung von 7,9 Teilen     Dimethyl-          aminchlorhydrat    versetzt. Man rührt, bis das  Dimethylamin beinahe verschwunden ist,  salzt aus, filtriert und trocknet.



  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 cyanuric chloride with one mole of 1. 8-aminonaphthol-3. 6-disulfonic acid and one mole of dimethylamine are obtained when one mole of 1.8-aminonaphthol-3.6-disulfonic acid and one mole of dimethylamine are allowed to act on one mole of cyanuric chloride in any order.



  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 hol. Dimethylamine forms a colorless, crystalline powder that is easily soluble in water. It still contains a reactive chlorine atom and is a valuable starting material for the production of dyes.

      Example: 31.9 parts of 1,8-aminonaphthol-3,6-disulfonic 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 com components have disappeared. The acidic solution obtained in this way is very carefully neutralized almost exactly and then, after adding 30 parts of crystallized sodium acetate, a solution of 7.9 parts of dimethylamine chlorohydrate is added. The mixture is stirred until the dimethylamine has almost disappeared, salted out, filtered and dried.
