Description

  

  Verfahren zur Herstellung eines     Küpenpräparates    aus einem     Cliinonwollkilpenfarbstoff     und     Ilalogenindigo.       In weiterer Ausarbeitung des Verfahrens  des Hauptpatentes     Nr.   <B>94851</B> wurde gefun  den,     dass    man ohne     Farbstoffverluste    ein  sehr gut lösliches     Küpenpräpaxat    aus     Di-          anilido-chinon-disulfid,    einem     brauDen        Woll-          küpenfarbstoff,

      welcher zum Beispiel nach'  der Vorschrift der deutschen Patentschrift       Nr.   <B>265195</B> oder nach dem Schweizer Patent       Nr.    59423 aus     Dianilido-dichlor-chinon    und  einem     Schwefelalkali    dargestellt werden  kann, erhält, indem man an Stelle von In  digo Halogenindigo verwendet.

   Man erhält  beim Eindampfen der Mischungen von     Ha-          logenindigoweissalkali    mit dem     Alka-Ii-Leuko-          salz    dieses     Chinonwollküpenfarbstoffes,    sei  es mit oder ohne Zusatz von verklebenden  Körpern, lockere,     leichtlöslielie        Küpenpräpa-          rate,

      welche in der Form von den     entspre-          ehenden        Indigoküpenpräparaten        haum    zu  unterscheiden sind und die gleiche     vorzüg-          lielle    Haltbarkeit besitzen wie die reinen       Indigo-K4enpräpa,ra,te,       <I>Beispiel:

  </I>  <B>250</B>     ko,        Monobrüm-Indigo        und   <B>100 kg</B>  der Farbstoffe aus     Dianilido-Dichlor-ellino-          nen    und     Schwefelnafrium,    hergestellt gemäss  der deutschen Patentschrift     Nr.   <B>265195</B> öder  deren     Zusätze*n,    werden in Form ihrer     Leuko-          verbindungen    in einer Mischung von<B>300 kg</B>       Natronlauo,e    40'     B#    und<B>300 kg</B> Wasser ge  löst.

   Nach Zugabe von<B>150</B> kg Melasse  <B>(50</B>     '/oig)    und<B>10 kg</B>     Hydrosulfit        techn.    wird  die Paste     bezw.    Flüssigkeit durch Vakuum  verdampfung zur Trockne und in lockere  feste Form gebracht. Das erhaltene, schau  mig lockere, schwarz glänzende     Küpenpro-          dukt    ist sehr gut haltbar     und    in Wasser  leicht zu einer gebrauchsfertigen     Küpe    lös  lich., welche auf Wolle rötlich schwarze Töne  erzeugt.

   Bei Anwendung derselben Menge  Halogenindigo und der doppelten Menge des  nach der     deutscheii        Patentechrift        Nr.   <B>265195</B>  erhältlichen     schwefel'haItigen        Chinonküpen-          fa,rbstoffes,    beziehungsweise dessen Leuko-           verbindungen    und entsprechender Änderung       der    Zusätze an     Natroulauge,    Melasse und       Hydrosulfit,    erhält man ein Produkt mit  ähnlichen Eigenschaften, das Wolle tief  schwarz färbt.



  Process for the production of a vat preparation from a Cliinonwollkilpen dye and Ilalogenindigo In a further elaboration of the process of the main patent no. <B> 94851 </B> it was found that a very soluble vat preparation made of dianilido-quinone disulfide, a brown wool vat dye, can be obtained without loss of dye.

      which, for example, can be prepared from dianilido-dichloro-quinone and an alkali-sulfur according to the specification of German patent specification no. <B> 265195 </B> or according to Swiss patent no. 59423 by replacing In digo Halogen indigo used.

   When evaporating the mixtures of halogen indigo white alkali with the Alka-II leuco salt of this quinone wool vat dye, be it with or without the addition of sticky bodies, loose, easily soluble vat preparations,

      which can be distinguished from the corresponding indigo vat preparations in terms of their shape and have the same excellent shelf life as the pure indigo k4en preparations, ra, te, <I> Example:

  </I> <B> 250 </B> ko, Monobrüm indigo and <B> 100 kg </B> of the dyestuffs from dianilido-dichloro-ellinene and sulfur-afrium, produced according to German patent specification no. <B> 265195 </B> or their additives * n, are dissolved in the form of their leuco compounds in a mixture of <B> 300 kg </B> soda lava, e 40 'B # and <B> 300 kg </B> water .

   After adding <B> 150 </B> kg molasses <B> (50 </B> '/ oig) and <B> 10 kg </B> hydrosulfite techn. is the paste respectively. Liquid is brought to dryness and loose solid form by vacuum evaporation. The fluffy, loose, shiny black vat product obtained has a very good shelf life and is easily soluble in water to form a ready-to-use vat, which produces reddish black tones on wool.

   When using the same amount of haloindigo and twice the amount of the sulfur-containing quinone vat, or its leuco compounds, obtainable according to German patent publication no. <B> 265195 </B>, or its leuco compounds and a corresponding change in the additions of sodium hydroxide, molasses and hydrosulfite , you get a product with similar properties that dyes wool deep black.
