Description

  

  Verfahren zur Herstellung eines neuen Zwischenproduktes der Teerfarbenindustrie.    Es wurde gefunden, dass man ein neues  Zwischenprodukt der     Teerfarbeni3.tdustrie,    das  2-(2 ,     5-Dichlor)-phenylamino-4    .     6-di-p-ogy-          naphthyl-l.    3.     5-triazin,    erhält, wenn man das  Kondensationsprodukt aus einem Molekül       Cyanurtrihalogenid    und einem Molekül 2 .     5-          Dichloranilin    auf     a-Naphthol    einwirken lässt.

    Das     2-(2.5-Dichlor)-phenylamino-4.6-di-p-          oxy-naphthyl-l.    3.     5-triazin    bildet ein hell  gelbes Pulver und löst sich in     Itzalkalien     mit gelber, in Schwefelsäure mit blauroter  Farbe. Es schmilzt, aus     Aceton-Xylol    um  gefällt, bei 155 bis<B>160'.</B> Es ist ein wert  volles Zwischenprodukt zur Herstellung von  Farbstoffen.  



       Beispiel:     <B>1.28</B> Teile des     Kondensationsproduktes     aus einem Molekül     Cyanurchlorid    und einem  Molekül     2.5-Dichloranilin    (Schmelzpunkt  120') werden zusammen mit     150    Teilen       a-Naphthol    in 1600 Teilen     Tetraclhloräthan     unter starkem Rühren eingetragen und mit  125 Teilen     Aluminiumchlorid    versetzt.

   Hier  auf rührt man längere Zeit bei 140', lässt  abkühlen und trennt die zähflüssige Reak-         tionsmasse    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 Essig  säure ausgefällt.



  Process for the production of a new intermediate product in the tar color industry. It has been found that a new intermediate product in the tar paint industry, 2- (2,5-dichloro) -phenylamino-4. 6-di-p-ogy-naphthyl-l. 3. 5-triazine, obtained when the condensation product of one molecule of cyanuric trihalide and one molecule of 2. 5- allows dichloroaniline to act on a-naphthol.

    2- (2.5-dichloro) -phenylamino-4,6-di-p-oxy-naphthyl-l. 3. 5-triazine forms a light yellow powder and dissolves in alkali with yellow, in sulfuric acid with blue-red color. When precipitated from acetone-xylene, it melts at 155 to <B> 160 '. </B> It is a valuable intermediate for the production of dyes.



       Example: 1.28 parts of the condensation product of one molecule of cyanuric chloride and one molecule of 2,5-dichloroaniline (melting point 120 ') 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 .

   Here the mixture is 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; where it disintegrates to an orange-red powder, then filtered, dissolved in dilute sodium hydroxide solution and the new triazine is precipitated by acetic acid.
