 Dieser bis jetzt noch nicht beschriebene Körper ist in kaltem Wasser sehr wenig, in heissem leichter löslich und kristallisiert aus diesem Lösungsmittel in Form feiner   Nädelchen. Wie   zu erwarten, besitzt er basische sowohl wie saure Eigenschaften und wird daher sowohl durch Säuren wie Alkalien gelöst. Er zeigt alle charakteristischen Reaktionen des 2.   6-Dioxy-

 This body, which has not yet been described, is very little soluble in cold water, more easily soluble in hot water and crystallizes from this solvent in the form of fine needles. As expected, it has both basic and acidic properties and is therefore dissolved by both acids and alkalis. It shows all the characteristic reactions of the 2. 6-dioxy-
