Description

  

  Verfahren zur Herstellung eines neuen     Wollfarbstoffes    der     Anthrachinonreihe.       Gegenstand der     -urliegenden    Erfindung  ist ein Verfahren zur Herstellung eines neuen  Wollfarbstoffes der     Anthrachinonreihe.    Das  selbe ist dadurch gekennzeichnet, dass man  das     Di-a-anthrachinonamid    des     2:2'-Dinitro-          4:

  4'-dicarboxydiphenyldisulfids    durch Behan  deln mit einem Reduktionsmittel in     3-Amino-          4    -     thiopherrol    -1-     carbonsäure-a-anthrachinon-          amid    überführt und dieses Produkt mit einer  Halogenessigsäure umsetzt. Der     Farbstoff    hat  die Formel  
EMI0001.0014     
    und färbt auf Wolle orangegelbe Töne, wel  che nach Behandlung mit verdünnter Schwefel  säure rein gelb und waschecht sind.  



       Beispiel:     22 Teile     2:2'-Dinitro-4:4'-dioarboxydi-          phenyldisulfid,    15 Teile     Thionylchlorid    und    200 Teile Nitrobenzol werden 20 Stunden  unter Umrühren und     Rückfluss    auf 100 bis  <B>1100</B> C erwärmt. Nach dieser Zeit hat sich  das gebildete Säurechlorid zu einer klaren  Lösung im Nitrobenzol aufgelöst. 22 Teile       a-Aminoanthrachinon    werden nun zugesetzt  und das Gemisch wird     2'/2    Stunden bei       130-1350    C umgerührt. Es entwickelt sich       Chlorwasserstoffsäure    und das Gemisch wird  dicker.

   Nach Abkühlung auf 40 o C wird die  gelbe,     krystallinische    Masse     abfiltriert    und  sukzessive mit     Nitrobenzol    und Alkohol ge  waschen.  



  Die so erhaltene Verbindung wird     1/2    Stunde  bei 30   C mit 2000 Teilen Wasser, 200     Tei-          len        33        %        Ätznatronlösung        und        120        Teilen          Natriumhydrosulfit    behandelt, wobei eine  klare Lösung entsteht. Hierauf werden  80 Teile     Natriumchloracetat    zugesetzt und  wird eine Stunde bei 60-70o C weiter um  gerührt.

   Sodann werden genügend Wasser  stoffperoxyd, um die Leuko-Anthrachinonver-           bindung    zu oxydieren, und Salz zugesetzt,  um das     Natriumsalz    des gebildeten     Tiogly-          colates    zu fällen. Die Fällung wird filtriert  und mit Salzwasser gewaschen. Das Produkt  ist ein orangegelbes Pulver, das in warmem  Wasser zu einer klar gelben Lösung löslich  ist.  



  Es kann nach der britischen Patentschrift  Nr. 377740 -auf Fasern angewandt werden.  Wolle wird orangegelb gefärbt, welcher  Ton sich nach Behandlung mit verdünnter  Schwefelsäure in ein reines Gelb umwandelt  und ausserordentlich waschecht ist.



  Process for the production of a new wool dye of the anthraquinone series. The present invention relates to a process for the preparation of a new wool dye of the anthraquinone series. The same is characterized in that the di-a-anthraquinonamide of 2: 2'-dinitro-4:

  4'-dicarboxydiphenyl disulfide is converted into 3-amino-4-thiopherrol -1-carboxylic acid-a-anthraquinone amide by treating with a reducing agent and this product is reacted with a haloacetic acid. The dye has the formula
EMI0001.0014
    and dyes orange-yellow shades on wool, which after treatment with dilute sulfuric acid are pure yellow and washable.



       Example: 22 parts of 2: 2'-dinitro-4: 4'-dioarboxydiphenyl disulfide, 15 parts of thionyl chloride and 200 parts of nitrobenzene are heated to 100 to 1100 ° C. for 20 hours with stirring and reflux. After this time, the acid chloride formed has dissolved to a clear solution in nitrobenzene. 22 parts of α-aminoanthraquinone are now added and the mixture is stirred at 130-1350 ° C. for 2½ hours. Hydrochloric acid develops and the mixture thickens.

   After cooling to 40 o C, the yellow, crystalline mass is filtered off and washed successively with nitrobenzene and alcohol.



  The compound obtained in this way is treated for 1/2 hour at 30 ° C. with 2000 parts of water, 200 parts of 33% caustic soda solution and 120 parts of sodium hydrosulfite, a clear solution being formed. 80 parts of sodium chloroacetate are then added and the mixture is stirred at 60-70 ° C. for a further hour.

   Sufficient hydrogen peroxide is then added to oxidize the leuco-anthraquinone compound, and salt is added to precipitate the sodium salt of the tioglycolate formed. The precipitate is filtered and washed with salt water. The product is an orange-yellow powder that dissolves in warm water to form a clear yellow solution.



  It can be applied to fibers according to British Patent No. 377740. Wool is dyed orange-yellow, which tone turns into a pure yellow after treatment with dilute sulfuric acid and is extremely washable.
