Description

  

  Verfahren zur     Herstellung    eines neuen Zwischenproduktes der Teerfarbenindustrie.    Es     wurde    gefunden,     d@ass    man ein neues       Zwischenpro:clhkt,    das     primäre        Kondensations-          prodult    von einem     Mol.        Cyanurchlorid    mit  einem     Mol.        1,8-Aminonaphthol-3,6-disulfo-          säure,    erhält,

   wenn man auf ein     Mül.        Cya-          nurchlorid    ein     Mol.        1,8-Am.nonaphthol-3,6-          disulf        osäure        einwirken        lässt.     



  Diese Kondensation wird durch Zusam  menrühren der Komponenten in     einem    geeig  neten Verdünnungsmittel     durchgeführt,    und  es wurde gefunden,     dass,    Tals solches Wasser in  überraschender Weise sehr .gut     geeignet    ist.  Das primäre Kondensationsprodukt aus einem       Mol.        Cyanurchlorid    mit einem     Mol.        1,8-          Amin.ona@phthol-3,6-disulfosäure    bildet ein in  Wasser leicht lösliches,     kristallinisches,    fast  farbloses Pulver.

   Es enthält noch zwei reak  tionsfähige Chloratome und stellt ein wert  volles     Ausgangsmaterial    zur Herstellung von  Farbstoffen dar.  



       Beispiel:     Eine     feine    Suspension von 18,5 Teilen       Cyanurchlorid    in 500     Teilen    Wasser     wird     unter     Rühren    vorsichtig und bei niedriger       Temperatur        mit    einer Lösung von 31,9 Teilen       1,8-Aminonaphthol-3,6-disulfosäure    und 13,3  Teilen 30     %iger        Natronlauge    in 150 Teilen    Wasser versetzt.

       Sobald    .das     Cyanurchlorid          verschwunden        ist,    wird das als heller     Nieder-          schlagausgefallene    primäre Kondensations  produkt von einem     Mol.        Cyanurchlorid        und     einem     Mol.        1,8-Aminonaphthol-3,6-disulfo-          säure    filtriert und getrocknet.



  Process for the production of a new intermediate product in the tar color industry. It was found that a new intermediate product, the primary condensation product of one mole of cyanuric chloride with one mole of 1,8-aminonaphthol-3,6-disulfonic acid, is obtained,

   when you go to a trash. Cyanuric chloride allows one mole of 1,8-Am.nonaphthol-3,6-disulfonic acid to act.



  This condensation is carried out by stirring the components together in a suitable diluent, and it has been found that, surprisingly, such water is very suitable. The primary condensation product of one mole of cyanuric chloride with one mole of 1,8-amin.ona @ phthol-3,6-disulfonic acid forms a crystalline, almost colorless powder that is easily soluble in water.

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



       Example: A fine suspension of 18.5 parts of cyanuric chloride in 500 parts of water is carefully stirred and at low temperature with a solution of 31.9 parts of 1,8-aminonaphthol-3,6-disulfonic acid and 13.3 parts of 30% strength Sodium hydroxide solution was added to 150 parts of water.

       As soon as the cyanuric chloride has disappeared, the primary condensation product of one mole of cyanuric chloride and one mole of 1,8-aminonaphthol-3,6-disulfonic acid, which has precipitated out as a pale precipitate, is filtered and dried.
