Description

Verfahren zur Herstellung von leicht löslichen Küpenfarbstoffpräparaten. Zusatz zum Patent 427 997. In weiterer Ausarbeitung des Verfahrens des Hauptpatents wurde gefunden, däß man auch dann leicht verküpbare Präparate erhält, wenn man die verteilend wirkenden sulfosauren Salze nicht in den Präparaten beläßt, sondern nach Behandlung der Farbstoffe mit ihnen dieselben wieder auswäscht. Auch hier kann die Behandlung mit den verteilend wirkenden Salzen durch Eindampfen bzw. Trocknen der Mischung von Farbstoffen 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.Process for the production of easily soluble vat dye preparations. Addition to patent 427 997. In further elaboration of the process of the main patent it was found that preparations which can easily be linked are obtained even if the dispersing sulfonic acid salts are not left in the preparations, but after Treating the dyes with them washes them out again. Here, too, the Treatment with the distributing salts by evaporating or drying the Mixing of dyes with solutions of the sulfonic acid salts is carried out, whereby also here it is advantageous to add free alkali, and then after The amount of alkali required for vatting is added again to the washout will.

Das vorliegende Verfahren besitzt vor dem des Hauptpatents den Vorteil, daß feste Küpenpräparate erhalten werden, die infolge des Fehlens der sulfosauren Salze höherprozentig sind als diejenigen des Hauptpatents. Auch ist es insofern von Vorteil, claß die sulfosauren Salze entfernt werden können, weil damit die Auswahl der Dispersionsmittel ohne Rücksicht auf deren etwaige unerwünschte Wirkung in der Küpe erfolgen kann, in welcher sie nicht mehr anwesend sind. Beispiel.The present process has the advantage over that of the main patent, that solid vat preparations are obtained, which due to the lack of sulfosauren Salts have a higher percentage than those of the main patent. It is also to that extent It is an advantage that the sulfonic acid salts can be removed, because this allows selection the dispersant regardless of their possible undesirable effect in the Can take place in which they are no longer present. Example.

2o 1.:g Di-(p-chloraniliclo-)benzochinon in Form von 5oprozentiger Paste werden in 5o 1 Wasser gut verteilt und mit 2 kg Monopolseife und 3 kg Natronlauge von 4.o° Be veltniseht. Diese Mischung wird eine Zeitlang auf etwa 6o° gehalten, darauf der Farbstoff abgesaugt. Das nach dem Trocknen erhaltene lockere Pulver wird schließlich mit 7 kg Ätznatron und 7 kg Hvdrosulfitpulver innig vermischt.2o 1.:g di- (p-chloraniliclo-) benzoquinone in the form of 5% Paste are well distributed in 5o 1 water and mixed with 2 kg monopole soap and 3 kg sodium hydroxide solution from 4.o ° Be veltniseht. This mixture is kept at about 60 ° for a while, then sucked off the dye. The loose powder obtained after drying is finally mixed intimately with 7 kg of caustic soda and 7 kg of Hvdrosulfitpulver.
