Description

  

  Verfahren     zier    Darstellung eines orange färbenden     liüpenfarbstofes    der       Antlia.ntlironr        eihe.       Es wurde gefunden,     dass    man den im  Hauptpatent Nr.     124528    erhaltenen     Küpen-          farbstoff    der     Anthanthronreihe    auch     erhäl+,     wenn man Chlor ohne Zusatz eines Verdün  nungsmittels auf     Anthanthron    bei Tempe  raturen unter 100   einwirken lässt.  



  Die Reaktion kann durch Zusatz eines       ;r(-eigneten        Katalysators    (Jod, Chlorjod oder       hienchlorid)    beschleunigt werden.  



  Trocken ist der so erhaltene     Küpenfarb-          ^ioff    ein orange gefärbtes Pulver, das sich  in konzentrierter Schwefelsäure mit grüner  Farbe löst. Er bildet mit alkalischem     Hv@ro-          sulfit    eine violette     Küpe,    aus der die       pflanzlichen    Fasern in gleichen Tönen an  gefärbt werden, die beim Verhängen oder  keifen in ein leuchtendes Gelborange von  hervorragenden Echtheitseigenschaften über-    <I>Beispiel:

  </I>  Über fein gepulvertes     Anthanthron,    dem  eine geringe Menge fein gepulvertes Jod  oder Eisenchlorid zugesetzt ist, wird unter       öfterem    Durchmischen Chlorgas bei gewöhn  licher Temperatur geleitet, bis eine 2 Atomen  Chlor entsprechende Gewichtszunahme statt  gefunden hat. Der zugesetzte Katalysator  wird auf die übliche Weise, zum Beispiel  durch gelindes Erwärmen im Vakuum oder  durch Behandeln mit einem geeigneten Lö  sungsmittel entfernt. Der so erhaltene chlo  rierte Farbstoff entspricht der wahrschein  lichen Formel:  
EMI0001.0023     
      Gelindes Erwärmen, etwa auf dem Was  serbade, beschleunigt den Prozess der Chlor-,       aufnahme.  



  Process ornamental representation of an orange-colored liuene dye of the Antlia.ntliron series. It has been found that the vat dye of the anthanthrone series obtained in main patent no. 124528 can also be obtained if chlorine is allowed to act on anthanthrone at temperatures below 100 without the addition of a diluent.



  The reaction can be accelerated by adding a suitable catalyst (iodine, chlorinated iodine or hiene chloride).



  When dry, the vat color obtained in this way is an orange colored powder which dissolves in concentrated sulfuric acid with a green color. With alkaline Hv @ rosulfite it forms a violet vat, from which the vegetable fibers are colored in the same tones, which when hanging or nipping into a bright yellow-orange with excellent fastness properties- <I> Example:

  </I> Over finely powdered anthanthrone, to which a small amount of finely powdered iodine or iron chloride has been added, chlorine gas is passed with frequent mixing at the usual temperature until a weight increase corresponding to 2 atoms of chlorine has taken place. The added catalyst is removed in the usual way, for example by gentle heating in vacuo or by treatment with a suitable solvent. The chlorinated dye obtained in this way corresponds to the probable formula:
EMI0001.0023
      Gentle warming, for example on a water bath, accelerates the process of chlorine absorption.

PATENTANSPRUCH: Verfahren zur Darstellung eines orange färbenden K'üpenfarbstoffes der Anthan- thronreihe, dadurch gekennzeichnet, dass man Chlor auf Anthanthron bei Temperaturen unter<B>100'</B> einwirken lässt. Trocken ist der so erhaltene Iiüpenfarb- stoff ein orange gefärbtes Pulver, das sich in konzentrierter Schwefelsäure mit grüner Farbe löst. PATENT CLAIM: Process for the preparation of an orange-colored vat dye of the anthanthrone series, characterized in that chlorine is allowed to act on anthanthrone at temperatures below <B> 100 '</B>. When dry, the pulp dye obtained in this way is an orange powder which dissolves in concentrated sulfuric acid with a green color. Er bildet mit alkalischem Hydro- sulfit eine violette Iiüpe, aus der die pflanzlichen Fasern in gleichen Tönen an gefärbt werden, die beim Verhängen oder Seifen in ein leuchtendes Gelborange von hervorragenden Echtheitseigenschaften über geben. UNTERANSPRUCH: Verfahren nach Patentanspruch, dadurch gekennzeichnet, da:ss man der Reaktions masse einen Katalysator zusetzt. Together with alkaline hydrosulphite it forms a violet lip from which the vegetable fibers are colored in the same tones, which when hung or soaped turn into a bright yellow-orange with excellent fastness properties. SUBCLAIM: Process according to claim, characterized in that: a catalyst is added to the reaction mass.
