Description

  

  Verfahren zur     Darstellung    eines Farbstoffes der     Anthrachinonr        eihe.       Es wurde gefunden, dass man durch Kon  densation von     1-Amino-4-halogenanthrachinon-          2-sulfosäuren    oder deren     Substitutionsproduk-          ten    mit solchen     monoacylierten        Arylendiami-          nen        bezw.    deren     Substitutionsprodukten,    in  welchen die     Acylgruppe    der allgemeinen  Formel       R=(CH        =CH)

  y-C4     entspricht, neue Kondensationsprodukte er  hält, welche sowohl als Wollfarbstoffe brauch  bar sind, insbesondere aber die Eigenschaft  besitzen, vegetabilische Fasern, wie zum Bei  spiel Baumwolle, Viskose und dergleichen,  direkt in kräftigen und echten Tönen anzu  färben. In obiger Formel bedeuten R einen       unsubstituierten    oder substituierten aromati  schen Rest, x eine der Zahlen 1 oder 2.  



  Dieselben     Farbstoffe    sind auch erhältlich,  wenn man ein     unsubatituiertes    oder substi-         tuiertes        Arylendiamin    halbseitig mit einer  7     -Amino-4-halogena.nthrachinon    - 2 -     sulfosäure     oder einem     Substitutionsprodukt    derselben  umsetzt, und dann die nicht in Reaktion ge  tretene     Aminogruppe    des     Arylendiamins    mit  einer Säure der oben angegebenen Formel       bezw.    einem reaktionsfähigen Derivat dersel  ben     acyliert.     



  Gegenstand vorliegenden Patentes ist ein  Verfahren zur Herstellung eines     Farbstoffes     der     Antbrachinonreihe,    dadurch gekennzeich  net, dass man     1-Amino-4-bromanthrachinon-          2-sulfosäure    mit     p-Amino-cinnamalacetanilid     kondensiert.  



  <I>Beispiel:</I>  10 Gewichtsteile     1-Amino-4-bromanthra-          chinon-2-sulfosäure    werden mit 5 Gewichts  teilen     p-Amino-cinnamalacetanilid        derFormel     
EMI0001.0037     
      8 Gewichtsteilen     Natriumbicarbonat,    0,5 Ge  wichtsteilen     Kupferchlorür    und einem Gemisch  von 100 Gewichtsteilen Wasser und 50 Ge  wichtsteilen Alkohol etwa 2 Stunden zum  Sieden erhitzt.

   Beim     Abküblen    scheidet sich  der neue Farbstoff in Form     bronceglänzender     Nadeln ab; die sich in Wasser mit klarer,  grüner     Farbe    lösen und Baumwolle aus dem       Glaubersalzbad    in kräftigen, grünen Tönen  von hervorragender Lichtechtheit anfärben.



  Process for the preparation of a dye of the anthraquinone series. It has been found that condensation of 1-amino-4-halogenanthraquinone-2-sulfonic acids or their substitution products with such monoacylated arylenediamines or. their substitution products, in which the acyl group of the general formula R = (CH = CH)

  y-C4 corresponds to new condensation products, which are usable both as wool dyes, but in particular have the property to dye vegetable fibers, such as cotton, viscose and the like, directly in strong and genuine tones. In the above formula, R is an unsubstituted or substituted aromatic radical, and x is one of the numbers 1 or 2.



  The same dyes are also available if one reacts an unsubstituted or substituted arylenediamine on one side with a 7-amino-4-halogena.nthraquinone - 2 - sulfonic acid or a substitution product of the same, and then the amino group of the arylenediamine which has not reacted with one Acid of the formula given above respectively. acylated a reactive derivative dersel ben.



  The present patent relates to a process for the preparation of a dye of the antbrachinone series, characterized in that 1-amino-4-bromoanthraquinone-2-sulfonic acid is condensed with p-amino-cinnamalacetanilide.



  <I> Example: </I> 10 parts by weight of 1-amino-4-bromoanthraquinone-2-sulfonic acid are combined with 5 parts by weight of p-amino-cinnamalacetanilide of the formula
EMI0001.0037
      8 parts by weight of sodium bicarbonate, 0.5 parts by weight of copper chloride and a mixture of 100 parts by weight of water and 50 parts by weight of alcohol heated to boiling for about 2 hours.

   When it cools down, the new dye is deposited in the form of shiny bronze needles; which dissolve in water with a clear, green color and dye cotton from the Glauber's salt bath in strong, green shades of excellent lightfastness.
