 auf dem Wasserbade am   Rücknusskühler   erhitzt, und dann im Verlauf von 3-4 Stunden Zinkstaub in kleinen Mengen   zugefügt,   bis die anfänglich blaue Farbe der   alkoholischen   Lösung in gelbgrün übergegangen ist, und eine Probe sich in   konzentrierter Schwefelsäure   nicht mehr rotviolett, sondern rein grün löst. Dazu werden etwa 4 Teile Zinkstanb gebraucht. Nach dem Erkalten wird der in grünlich gelben Nadeln ausgeschiedene Farbstoff abfiltriert und getrocknet. In den Mutterlaugen lässt sich leicht Anilin nachweisen. Der Farbstoff ist in reinem Wasser leicht löslich, zunächst farblos, dann rasch blau werdend. In schwach angesäuertem Wasser bleibt die Lösung farblos, resp. schwach gelblich.

   Mit Chrombeize auf Baumwolle gedruckt, wird durch Dämpfen ein kräftiges reines Blau erhalten. 



   Beispiel II. 10 Teile eines anilidierten Gallocyanins werden mit 150 Teilen Alkohol   angeschwemmt   und nach Zusatz von 1 Teil Zinkstaub und 1 Teil Salzsäure zum schwachen Sieden erwärmt. Dann werden abwechslungsweise 3 Teile Zinkstaub und 24 Teile Salzsäure zugegeben, bis eine Probe in konzentrierter Schwefelsäure sich rein grün löst. Nach dem Erkalten wird der abgeschiedene Farbstoff von der Mutterlauge getrennt. 



   In obigen Beispielen kann der zur Verwendung gelangende Alkohol durch Wasser oder t'in anderes geeignetos Lösungsmittel ersetzt werden, und an Stelle der Gallocyaninarylide können selbstverständlich auch deren Sulfoderivate verwendet werden.

 Heated in the water bath on the re-nut cooler, and then zinc dust was added in small amounts over the course of 3-4 hours until the initially blue color of the alcoholic solution has turned yellow-green and a sample no longer dissolves red-violet, but pure green in concentrated sulfuric acid . About 4 parts of zinc rod are needed for this. After cooling, the dye which has separated out in greenish yellow needles is filtered off and dried. Aniline can easily be detected in the mother liquors. The dye is easily soluble in pure water, initially colorless, then quickly turning blue. In weakly acidified water, the solution remains colorless, respectively. pale yellowish.

   Printed on cotton with chrome stain, steaming creates a strong, pure blue.



   Example II. 10 parts of anilidized gallocyanine are washed ashore with 150 parts of alcohol and, after the addition of 1 part of zinc dust and 1 part of hydrochloric acid, are heated to a gentle boil. Then 3 parts of zinc dust and 24 parts of hydrochloric acid are added alternately until a sample dissolves in concentrated sulfuric acid in a pure green color. After cooling, the deposited dye is separated from the mother liquor.



   In the above examples, the alcohol used can be replaced by water or another suitable solvent, and of course their sulfoderivatives can also be used instead of the gallocyaninarylides.
