Description

  

      Verfahren'    zur Herstellung eines neuen Zwischenproduktes der     Teerfarbenindustrie.       Es wurde gefunden, dass man ein neues  Zwischenprodukt der Teerfarbenindustrie, das       2-o-Tolylamino-4,        6-di-p-ogy-naphthyl-1,    3,     5-          triazin,    erhält, wenn man das Kondensations  produkt aus einem Molekül     Cyanurtrihalöge-          nid    und einem Molekül     o-Toluidin    auf     a-Naph-          thol    einwirken lässt.

   Das     2-o-Tolylamino-4,    6  di-p-ogy-naphthyl-1, 3,     5-triazin    bildet ein hell  gelbes Pulver und löst sich in     Ätzalkalien     mit gelber, in Schwefelsäure mit blauroter  Farbe. Es schmilzt, aus     Aceton-gylol    'umge  fällt, bei 195   unter vorheriger     Sinterung    von  190   an. Es ist ein wertvolles Zwischenpro  dukt zur Herstellung von     Farbstoffen.     



  <I>Beispiel:</I>  128 Teile des Kondensationsproduktes aus  einem Molekül     Cyanurchlorid    und einem Mo  lekül     o-Toluidin    werden zusammen mit 150  Teilen     a-Naphthol    in 1600 Teilen     Tetrachlor-          äthan    unter starkem Rühren eingetragen und  mit 125 Teilen Aluminiumchlorid versetzt.  Hierauf rührt man längere Zeit bei 140  ,  lässt abkühlen und trennt die zähflüssige Re  aktionsmasse vom Verdünnungsmittel durch    Abgiessen. Das Reaktionsprodukt wird nun  mit verdünnter Salzsäure ausgekocht, wobei es  zu einem orangeroten Pulver zerfällt, hierauf  filtriert, in verdünnter Natronlauge gelöst und  das neue     Triazin    durch Essigsäure ausgefällt.



      Process for the production of a new intermediate product in the tar color industry. It has been found that a new intermediate in the tar color industry, the 2-o-tolylamino-4, 6-di-p-ogy-naphthyl-1, 3, 5-triazine, is obtained when the condensation product is obtained from a molecule of cyanuric trihalogen - Nid and one molecule of o-toluidine can act on a-naphthol.

   The 2-o-tolylamino-4, 6-di-p-ogy-naphthyl-1, 3, 5-triazine forms a light yellow powder and dissolves in caustic alkalis with yellow, in sulfuric acid with blue-red color. It melts, from acetone-glycol 'the other way around, at 195 with previous sintering from 190 on. It is a valuable intermediate product in the manufacture of dyes.



  <I> Example: </I> 128 parts of the condensation product of one molecule of cyanuric chloride and one molecule of o-toluidine are introduced together with 150 parts of a-naphthol in 1600 parts of tetrachloroethane with vigorous stirring, and 125 parts of aluminum chloride are added. The mixture is then stirred for a long time at 140, allowed to cool and the viscous reaction mass is separated from the diluent by pouring off. The reaction product is now boiled with dilute hydrochloric acid, whereupon it disintegrates to an orange-red powder, then filtered, dissolved in dilute sodium hydroxide solution and the new triazine is precipitated with acetic acid.
