Description

  

      Verfahren    zur Herstellung eines neuen     Zwischenproduktes    der Teerfarbenindustrie.    Es -wurde gefunden,     da.ss,    man ein neues  Zwischenprodukt, das sekundäre Kondensa  tionsprodukt von einem     Mol.        Cyanurchlorid     mit zwei     Mol.    Anilin, erhält, wenn man auf  ein     Mol.        Cya.nurchlorid    zwei     Mol.    Anilin ein  wirken 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 sekundäre Kondensationsprodukt aus  einem     Mol.        Cyanurchlorid    mit zwei     Mol.    Ani  lin bildet ein in Wasser unlösliches, fast farb  loses Pulver. Aus     Aceton-Petroläther    umge  löst, schmilzt es bei 196     bis    197  . Es ent  hält noch ein reaktionsfähiges Chloratom und  stellt ein wertvolles Ausgangsmaterial zur  Herstellung von Farbstoffen dar.

      <I>Beispiel:</I>    Zu einer Suspension von 18,5 Teilen     Cya-          nurchlorid    in der 30fachen Menge Wasser  werden in der Kälte 9,3 Teile Anilin, in 20  Teilen Aceton gelöst, gegeben und so lange  gerührt, bis gerade 3,65 Teile Salzsäure frei    geworden sind. Das Reaktionsprodukt wird  filtriert und der Filterrückstand, in Aceton  gelöst, in eine auf 40' erwärmte Suspension  von 18,6 Teilen Anilin in 1000 Teilen Was  ser eingetragen. Sobald 3,65 Teile Salzsäure  frei geworden sind, wird filtriert und ge  trocknet.



      Process for the production of a new intermediate product in the tar color industry. It was found that a new intermediate product, the secondary condensation product of one mole of cyanuric chloride with two moles of aniline, is obtained if two moles of aniline are allowed to act on one mole of cyanuric chloride.



  This condensation is carried out by stirring the components together in a suitable diluent, and it has been found that water is surprisingly very suitable as such. The secondary condensation product of one mole of cyanuric chloride with two moles of aniline forms a water-insoluble, almost colorless powder. Dissolved from acetone petroleum ether, it melts at 196 to 197. It still contains a reactive chlorine atom and is a valuable starting material for the production of dyes.

      <I> Example: </I> To a suspension of 18.5 parts of cyanuric chloride in 30 times the amount of water, 9.3 parts of aniline, dissolved in 20 parts of acetone, are added and stirred until just 3 , 65 parts of hydrochloric acid have 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.
