Description

  

  Verfahren zur Darstellung eines     Farbstoffes.       Es wurde gefunden, dass man zu einem  gelben     Küpenfarbstoff    von vorzüglichen  Echtheitseigenschaften gelangt,     wenn    man  das     Naphtsulta.m-3    . 4 -     phenazin,    das man  durch Kondensation von     Oxynaphtsultam-          ehinon    und 1     .2-Diamino-4-methylbenzol    er  halten kann, mit     2.3-Dichlor-1.4-naphto-          cliinon    in Gegenwart eines säurebindenden  Mittels erhitzt.  



  <I>Beispiel:</I>  3,2 Teile des     Naphtsultam-3    .     4-phena.zins,     das durch Kondensation von     Oxynaphtsultam-          chinon    und 1 .     2-Diamino-4-methylbenzol    dar  gestellt werden kann, 2,3 Teile 2 .     3-Dichlor-          1.4-na@phtochinon,    2 Teile entwässertes Na  triumacetat und 80 Teile Nitrobenzol werden       zwei    Stunden auf 140 bis<B>150'</B> erhitzt. Nach  dem Erkalten wird der kristallinische abge  schiedene Farbstoff abgesaugt. Er färbt die         tierische    oder pflanzliche Faser, z. B.

   Baum  wolle, aus der     Hydrosulfitküpe    in klaren,       grünstichig-gelben,    chlor- und seifenechten  Tönen.



  Process for the preparation of a dye. It has been found that a yellow vat dye with excellent fastness properties is obtained if the Naphtsulta.m-3. 4-phenazine, which can be obtained by condensation of oxynaphtsultameinone and 1,2-diamino-4-methylbenzene, heated with 2,3-dichloro-1,4-naphthocliinone in the presence of an acid-binding agent.



  <I> Example: </I> 3.2 parts of naphtsultam-3. 4-phena.zins, which is formed by the condensation of oxynaphtsultamquinone and 1. 2-diamino-4-methylbenzene can be made, 2.3 parts of 2. 3-dichloro 1.4-na@phtochinon, 2 parts of dehydrated sodium acetate and 80 parts of nitrobenzene are heated to 140 to 150 'for two hours. After cooling, the crystalline abge separated dye is filtered off with suction. It colors the animal or vegetable fiber, e.g. B.

   Cotton from the hydrosulfite vat in clear, greenish-yellow, chlorine- and soap-proof tones.
