  Verfahren zur Herstellung eines neuen Zwischenproduktes der     Teerfaruenludustrie.       Es wurde gefunden, dass man ein neues  Zwischenprodukt, das sekundäre Kondensa  tionsprodukt von einem     Mol.        Cyanurchlorid     mit einem     Mol.    Anilin und einem     Mol.1-Amino-          4-clilorbenzol,    erhält, wenn man auf ein     Alol.          Cyanurchlorid    in beliebiger Reihenfolge ein       Mol.    Anilin- und ein     Mo).        1-Amino-4-chlor-          benzal    einwirken lässt.  



  Diese     Kondensation    wird durch     Zus.am-          inenrühren    der Komponenten in einem geeig  neten Verdünnungsmittel durchgeführt, und  es     wurde    gefunden,     da.ss    Wasser als     solches    in       überraschender    Weise sehr gut geeignet ist.

    Das sekundäre Kondensationsprodukt aus  einem     Mol.        Cyanurchlorid    mit einem     Mol.     Anilin und einem     Ivfol.        1-Amino-4-chlorben-          zol    bildet, ,aus Aceton umkristallisiert, ein fast       farbloses,        kristallinisiches    Pulver vom     Fp.     <B>190'.</B> Es enthält noch ein reaktionsfähiges  Chloratom und stellt ein wertvolles Ausgangs  material zur Herstellung von     Farbstoffen,dar.     <I>Beispiel:

  </I>  Zu einer Suspension von 18,5 Teilen     Cya-          nurclilorid    in der 30fachen Menge Wasser  werden in der Kälte 17,7 Teile     1-Amino-4-          chlorbenzol,    in 20 Teilen Aceton gelöst, gege  ben und so lange gerührt, bis gerade 3,65    Teile Salzsäure frei geworden sind. Das     Re-          aldionsprcdukt    wird filtriert und der Filter  rückstand, in Aceton gelöst, in eine ,auf 40    erwärmte     Suspension    von 18,6 Teilen Anilin  in 1000 Teilen     Nasser    eingetragen. .Sobald  3,65 Teile Salzsäure frei geworden sind, wird  filtriert und getrocknet.



  Process for the production of a new intermediate product for the tar fruity industry. It has been found that a new intermediate product, the secondary condensation product of one mole of cyanuric chloride with one mole of aniline and one mole of 1-amino-4-clilobenzene, is obtained if one uses an Alol. Cyanuric chloride in any order, one mole. Aniline and one Mo). Lets 1-amino-4-chlorobenzal take effect.



  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 secondary condensation product of one mole of cyanuric chloride with one mole of aniline and one Ivfol. 1-Amino-4-chlorobenzene, when recrystallized from acetone, forms an almost colorless, crystalline powder with a melting point of <B> 190 '. </B> It still contains a reactive chlorine atom and is a valuable starting material for the production of Dyes. <I> example:

  </I> 17.7 parts of 1-amino-4-chlorobenzene, dissolved in 20 parts of acetone, are added to a suspension of 18.5 parts of cyanurucliloride in 30 times the amount of water and stirred until 3.65 parts of hydrochloric acid have just been released. The reaction product is filtered and the filter residue, dissolved in acetone, is added to a suspension, heated to 40, of 18.6 parts of aniline in 1000 parts of water. As soon as 3.65 parts of hydrochloric acid have become free, it is filtered and dried.
