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.
