Description

  

  Leichtlösliches, stabiles     Nüpenfarbstoffpräparat.       In weiterer Ausbildung der     Erfindung     nach Hauptpatent Nr. 114285, leichtlösliche,  stabile     Küpenfarbstoffpräparate    betreffend,  wurde gefunden, dass man auch dann leicht       verküpbare,    stabile Präparate erhält, wenn  man die Farbstoffe mit verteilend     wirkenden          sulfosauren    Salzen behandelt, hierauf von  diesen zum Beispiel durch Waschen trennt  und dann mit Alkali und     Hydrosulfit    mischt.

    Auch hier kann die Behandlung mit den  verteilend wirkender) Salzen durch Eindamp  fen     bezw.    Trocknen der Mischung von Farb  stoffen mit Lösungen der     sulfosauren    Salze  erfolgen, wobei auch hier vorteilhaft freies  Alkali hinzugefügt werden kann, wobei dann  nach erfolgter Auswaschung von neuem die  für die     Verküpung    erforderliche     Alkalimenge     zugesetzt wird.  



  Die gemäss dem vorliegenden Verfahren  erhaltenen festen Präparate haben gegenüber  denjenigen des' Hauptpatentes den Vorteil,  an Farbstoff höher     prozentig    zu sein; auch  kann die Auswahl der     Dispersionsmittel    ohne    Rücksicht auf deren etwaige unerwünschte  Wirkung in der     Küpe    erfolgen.    <I>Beispiel:</I>    20 kg     Di-(-p-chloi-anilido)-benzochinon.    in  Form von 50     o/oiger    Paste werden in 50 lt  Wasser gut verteilt und mit 2 kg Monopol  seife und 3 kg Natronlauge von 40       B6    ver  mischt. Diese Mischung wird eine Zeitlang  auf etwa 60   gehalten, darauf der Farbstoff  abgesaugt.

   Das nach dein Trocknen erhal  tene lockere Pulver wird schliesslich mit  7 kg     Ätznatron    und 7 kg     Hydrosulfitpulver     innig vermischt.



  Easily soluble, stable pomace dye preparation. In a further development of the invention according to main patent no. 114285, relating to easily soluble, stable vat dye preparations, it was found that stable preparations that are easily vatted are also obtained if the dyes are treated with dispersing sulfonic acid salts and then separated from them, for example by washing and then mixes with alkali and hydrosulfite.

    Here, too, the treatment with the distributing salts can be or by evaporation. Drying of the mixture of dyestuffs with solutions of the sulfonic acid salts takes place, in which case free alkali can also advantageously be added, in which case the amount of alkali required for vatting is then added again after washing out.



  The solid preparations obtained according to the present process have the advantage over those of the main patent that they contain a higher percentage of dye; the selection of the dispersants can also be made regardless of their possible undesirable effects in the vat. <I> Example: </I> 20 kg di - (- p-chloi-anilido) -benzoquinone. in the form of 50% paste are well distributed in 50 liters of water and mixed with 2 kg of monopoly soap and 3 kg of 40 B6 sodium hydroxide solution. This mixture is kept at about 60 for a while, then the dye is suctioned off.

   The loose powder obtained after drying is finally intimately mixed with 7 kg of caustic soda and 7 kg of hydrosulfite powder.
