Description

  

  Verfahren zur Herstellung eines neuen Zwischenproduktes der Teerfarbenindustrie.    Es     wurde    gefunden,     cl.a.ssi    man ein neues       Zwischenprodukt,    das primäre     Kondensa-          ti.onsprodukt    von einem     Mol.        Cyanurchlorid     mit einem     Mol.        1,4-Chloranilin    erhält, wenn  man auf.     Cyanurchlorid    ein     Mol.        1,4-Chlor-          anilin        einwirken    lässt.  



  Diese Kondensation wird durch Zusam  menrühren der Komponenten in einem geeig  neten Verdünnungsmittel     dur.cllgeführt,    und  es     wurde    gefunden, dass Wasser als solches  in überraschender Weise sehr gut geeignet  ist. Das primäre     Kondensationsproduke    aus  einem     Mol.        Cyanurchlorid    mit einem     Mol.          1,4-Chloranilin    bildet. ein weisses Pulver, das  bei<B>190'</B> schmilzt. Es enthält noch zwei re  aktionsfähige Chloratome und stellt ein wert  volles Ausgangsmaterial zur Herstellung von       Farbstoffen    dar.  



       Beispiel:     7u einer Suspension von 18,5 Teilen     Cya-          nurchlorid    in der     20fachen    Menge Wasser  werden in der Kälte 12,7 Teile 1,4-Chlorani-         lin    in 20 Teilen Aceton gelöst, zugegeben und  so lange gerührt, bis 3,6 Teile     Salzsäure    frei  geworden sind. Das Reaktionsprodukt wird       filtriert    und der Filterrückstand aus Eisessig       kristallisiert.  



  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 condensate product of one mole of cyanuric chloride with one mole of 1,4-chloroaniline, is obtained when on. Cyanuric chloride allows one mole of 1,4-chloroaniline 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 forms from one mole of cyanuric chloride with one mole of 1,4-chloroaniline. a white powder that melts at <B> 190 '</B>. It still contains two reactive chlorine atoms and is a valuable starting material for the production of dyes.



       Example: 12.7 parts of 1,4-chloroaniline in 20 parts of acetone are dissolved in the cold in a suspension of 18.5 parts of cyanuric chloride in 20 times the amount of water, and the mixture is stirred until 3.6 parts Hydrochloric acid have become free. The reaction product is filtered and the filter residue is crystallized from glacial acetic acid.
