Description

  

      Zusatzpatent    zum Hauptpatent     Nie    247444.    Verfahren zur Herstellung eines     Küpenfarbstoffes.       Es wurde gefunden, dass ein wertvoller       Küpenfarbstoff    hergestellt werden kann,  wenn man das in alkalischem Medium er  balten.e     Kondensationsprodukt    aus     1-(Bzl-          henzanthronylamino)    - 5 -     aminoanthra.chinon     Mit einem Mittel behandelt, das den Rest der  
EMI0001.0009     
  
     Der.     neue    Farbstoff ist ein     olives        Pul-          v:

  @r,    das sich in Schwefelsäure grün löst und       :ois        rotstichig    blauer     Küpe    Baumwolle oder       Wllwolle    in     gelbstichig    oliven Tönen färbt:.  



       Das    dem vorliegenden Verfahren als Aus  gangsprodukt dienende     alkalische    Konden  sationsprodukt aus:     1-(Bzl-Benzanthronyl-          amino)-5-aminoanthrachinon    kann in     beka-nn-          terWeise    erhalten werden, z. B. unter Ver  wendung von alkoholischen     ÄtzallLa:lilösun-          gen    bzw. Schmelzen     (vergl.    französische     Pa-          ientschriften        Nr.697231    und     ä96583).     



  Als Mittel, die den Rest der obigen For  mel abgeben, kommen     vorzugsweise        reak-          iionsfähige,    funktionelle Derivate der     2,4-          Diehlorbenzoesäure,    z.     Bi.,    die     Säurehaloi-          genide    und     insbes,ondere    das Säurechlorid,  in Betracht.  



  Die Behandlung kann in an sich bekann  ter     ZVeise    z. B. durch Erhitzen in     indiffe-          rentün,    vorzugsweise hochsiedenden Lösungs  mitteln wie Nitrobenzol, Naphthalin und       Diehlorbenzol    vorgenommen werden.  



       Beispiel:     ?0 Teile     a.lkal.    Kondensationsprodukt aus  1- (Bzl-Benzanthronylamino)-5-aminoanthra-         chinon    werden in 250 Teilen     Nitrobenzol    mit  30 Teilen     2,4-Dichlorbenzoylchlorid    erwärmt  und 21     Stunden    rückfliessend gekocht. Nach  Erkalten wird abgesaugt; der Rückstand wird  zuerst mit Nitrobenzol, dann mit Chlorben  zol, hierauf mit Alkohol     und    schliesslich mit  Wasser     gewaschen    und nach Erreichung  einer neutralen Reaktion getrocknet.



      Additional patent to the main patent Nie 247444. Process for the production of a vat dye. It has been found that a valuable vat dye can be produced if the condensation product of 1- (benzanthronylamino) -5-aminoanthraquinone is treated with an agent that treats the rest of the
EMI0001.0009
  
     Of the. new dye is an olive powder:

  @r, which dissolves green in sulfuric acid and: ois reddish-tinged blue vat dyes cotton or wool in yellow-tinged olive tones :.



       The alkaline condensation product from: 1- (Bzl-benzanthronyl-amino) -5-aminoanthraquinone, which serves as the starting product for the present process, can be obtained in a known manner, e.g. B. using alcoholic caustic solutions or melts (see French patent publications No. 697231 and 96583).



  The agents that release the remainder of the formula above are preferably reactive, functional derivatives of 2,4-dichlorobenzoic acid, eg. Bi., The acid halides and especially the acid chloride, into consideration.



  The treatment can be carried out in ZVeise known per se z. B. be made by heating in indifferent, preferably high-boiling solvents such as nitrobenzene, naphthalene and diehlorbenzene.



       Example:? 0 parts a.lcal. Condensation product of 1- (Bzl-benzanthronylamino) -5-aminoanthraquinone are heated in 250 parts of nitrobenzene with 30 parts of 2,4-dichlorobenzoyl chloride and refluxed for 21 hours. After cooling down, suction is performed; the residue is washed first with nitrobenzene, then with chlorobenzene, then with alcohol and finally with water and dried after a neutral reaction has been achieved.
