Description

  

  Verfahren zur Herstellung eines neuen Zwischenproduktes der Teerfarbenindustrie.    Es wurde gefunden,     d.ass    man ein neues  Zwischenprodukt, das primäre Kondensations  produkt von einem     Mol.        Cyanurchlorid    mit  einem     Mol.        1-Amino    - 3 -     nitrobenzol,    erhält,  wenn man auf ein     Mol.        Cyanurchlorid    ein  Hol.     1-Amino-3-nitrobenzol    einwirken lässt.  



  Diese Kondensation     wird    durch Zusam  menrühren der Komponenten in einem geeig  neten Verdünnungsmittel durchgeführt,     und     es wurde gefunden, dass Wasser als solches in  überraschender Weise sehr gut geeignet ist.  Das primäre Kondensationsprodukt .aus einem       Mol.        Cya.nurchlorid    mit     einem        112o1.        1-Amino-          3-nitrobenzol    bildet ein in Wasser unlösliches,  fast farbloses Pulver. Aus Aceton umgelöst,  schmilzt es bei 202'.

   Beim Übergiessen mit  10     %iger    Natronlauge wandelt es sich in .einen  voluminösen     orangegefärbten        Körper    um, ,der  sich in kaltem Wasser mit     grünlichgelber     Farbe löst. Es enthält noch zwei reaktions  fähige Chloratome und bildet ein wertvolles  Ausgangsmaterial zur Herstellung von Farb  stoffen.    <I>Beispiel:</I>  Eine feine Suspension von 18,6 Teilen       Cyanurchlorid    wird unter Rühren mit einer  Lösung von 17,4 Teilen     1-Amino-3-nitroben-          zöl    versetzt und so lange gerührt, bis das     1-          Amino-3-nitrobenzol    fast verschwunden ist.

    Der gebildete kristallinische     Niederschlag     wird dann filtriert und getrocknet.



  Process for the production of a new intermediate product in the tar color industry. It has been found that a new intermediate, the primary condensation product of one mole of cyanuric chloride with one mole of 1-amino-3-nitrobenzene, is obtained when one mole of cyanuric chloride is used. 1-Amino-3-nitrobenzene is allowed to act.



  This condensation is carried out by stirring the components together in a suitable diluent, and it has been found that water as such is surprisingly very suitable. The primary condensation product of one mole of cyano chloride with a 112o1. 1-Amino-3-nitrobenzene forms an almost colorless powder which is insoluble in water. Dissolved from acetone, it melts at 202 '.

   When 10% sodium hydroxide solution is poured over it, it changes into a voluminous orange-colored body, which dissolves in cold water with a greenish-yellow color. It still contains two reactive chlorine atoms and is a valuable starting material for the production of dyes. <I> Example: </I> A fine suspension of 18.6 parts of cyanuric chloride is mixed with a solution of 17.4 parts of 1-amino-3-nitrobenzöl while stirring and the mixture is stirred until the 1- amino- 3-nitrobenzene has almost disappeared.

    The crystalline precipitate formed is then filtered and dried.
