Description

  

  Verfahren zur Herstellung eines neuen Zwischenproduktes der Teerfarbenindustrie.    Es wurde gefunden, dass man ein neues       Zwischenprodukt    der     Teerfarbenindustrie,     das     2-Chlor-4-o-tolylamino-6-p-oxy-naphthyl-          1,    3,     5-triazin,    erhält, wenn man     ein    Molekül  des Kondensationsproduktes aus einem Mole  kül     Cyanurchlorid    und einem     Molekül-o-          Toluidin    auf ein Molekül     a-Naphthol,

      gege  benenfalls in     Gegenwart    von     Kondensations-          mitteln    und von     Verdünnungsmitteln    einwir  ken lässt. Das     2-Chlor-4-o-tolylamino-6-p-          oxy-naphthyl-1,    3,     5-triazin    bildet als Chlor  wasserstoffverbindung ein     gelboranges    Pul  ver; es löst sieh in     Itzalkalien    mit gelber, in       konzentrierter    Schwefelsäure mit oranger  Farbe. Es ist ein wertvolles Zwischenpro  dukt zur Herstellung von     Farbstoffen.     



  <I>Beispiel: .</I>  



  In 1600 Teilen     Tetrachloräthau    werden  unter     Eiskühlung    51,2 Teile des Kondensa  tionsproduktes aus einem Molekül     Cyanur-          chlorid    und einem Molekül     o-Toluidin    zu  sammen mit 29 Teilen     a-Naphthol    und 51  Teilen Aluminiumchlorid eingetragen. Man  rührt längere Zeit, wobei man die Tempera-         tur    allmählich bis<B>15'</B> steigen lässt, bläst das  Verdünnungsmittel mit     Wasserdampf    aus  und trocknet den Rückstand.

   Dieser wird in  Aceton gelöst, die so     erhaltene    Lösung schei  det beim Einleiten von     Chlorwasserstoffgas     die     Doppelverbindung    des     2-Chlor-4-o-tolyl-          amino-6-p-oxy-nap,hthyl    - 1, 3, 5 -     triazins    in  Form eines gelborangen Pulvers aus.



  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-chloro-4-o-tolylamino-6-p-oxy-naphthyl-1, 3, 5-triazine, is obtained if one molecule of the condensation product is obtained from one mole kül cyanuric chloride and one molecule of o-toluidine to one molecule of a-naphthol,

      if necessary, can act in the presence of condensation agents and diluents. The 2-chloro-4-o-tolylamino-6-p-oxy-naphthyl-1, 3, 5-triazine forms a yellow-orange powder as a hydrogen chloride compound; It dissolves in alkali with yellow, in concentrated sulfuric acid with orange color. It is a valuable intermediate product in the manufacture of dyes.



  <I> Example:. </I>



  In 1600 parts of tetrachloroethane 51.2 parts of the condensation product of one molecule of cyanuric chloride and one molecule of o-toluidine are entered together with 29 parts of a-naphthol and 51 parts of aluminum chloride while cooling with ice. The mixture is stirred for a long time, the temperature being allowed to rise gradually to <B> 15 '</B>, the diluent is blown out with steam and the residue is dried.

   This is dissolved in acetone, the solution obtained in this way separates the double compound of 2-chloro-4-o-tolylamino-6-p-oxy-nap, ethyl-1, 3, 5-triazine in the form when hydrogen chloride gas is introduced a yellow-orange powder.
