 zukommt, ist in Ammoniak und Soda unlöslich, löslich in Natronlauge besonders beim Entwärmen mit grünblaue Farbe. Die Lösung in Schwefelsäure ist gelb und wird durch Borsäure blau und zeigt nun ein Spektrum, welches dem der Ausgangsstoffe sehr ähnlich ist. In Pastenform oder in Form ihres Natronsalzes färbt die neue Verbindung   chromierte   Wolle in echten blauen Tönen. 



   In gleicher Weise werden aus den anderen nach dem Patent Nr. 108683 erhältlichen Verbindungen die Sulfogruppe abgespalten.

 EMI1.2
 is insoluble in ammonia and soda, soluble in caustic soda, especially when it is cooled, with a green-blue color. The solution in sulfuric acid is yellow and becomes blue with boric acid and now shows a spectrum that is very similar to that of the starting materials. In paste form or in the form of its sodium salt, the new compound dyes chromed wool in real blue tones.



   In the same way, the sulfo group is split off from the other compounds obtainable according to patent no. 108683.
