, Zusatz zum Patente 192971 vom I.September 1906., Addendum to the patent 192971 of September 1, 1906.
Patentiert im Deutschen Reiche vom 20. April 1907 ab. Längste Dauer: 31. August 1921.Patented in the German Empire on April 20, 1907. Longest duration: August 31, 1921.
In dem Hauptpatent ist ein Verfahren zur Darstellung eines neuen Farbstoffs aus Gallocyanin beschrieben, welches darin besteht, daß man Gallocyaninbase oder ihre Alkalisalze in wässeriger Lösung oder Suspension erhitzt.In the main patent is a process for the preparation of a new dye from gallocyanin described, which consists in the fact that one Gallocyaninbase or its alkali salts heated in aqueous solution or suspension.
Es wurde nun gefunden, daß die Ausführung dieser Reaktion nicht auf die Anwendung von Wasser als Verdünnungsmittel ίο beschränkt ist, sondern sich auch in anderen geeigneten Medien, wie z. B. Alkoholen, Nitrobenzol usw., vollzieht.It has now been found that performing this reaction is not applicable to the application is limited by water as a diluent ίο, but also in others suitable media, such as B. alcohols, nitrobenzene, etc., takes place.
30 kg Gallocyaninbase werden in 200 1 Amylalkohol eingetragen und unter Rühren und Rückflußkühlung zum Sieden erhitzt, bis eine Probe sich in Salzsäure von 200 Be. rein blau löst. Die Reaktion erfordert etwa 6 Stunden. Nach dem Erkalten preßt man die abgeschiedene Farbstoff base ab und führt säe in das salzsaure Salz über.30 kg of Gallocyaninbase are introduced into 200 l of amyl alcohol and heated to boiling with stirring and reflux cooling until a sample is in hydrochloric acid of 20 0 Be. pure blue solves. The reaction takes about 6 hours. After cooling, the deposited dye base is pressed off and the seeds are transferred to the hydrochloric acid salt.
Verwendet man niedrig siedende Mittel, wie Methyl- oder Äthylalkohol, so ist es zweckmäßig, unter Druck bei über dem Siedepunkt des verwendeten Mittels liegenden Temperaturen zu arbeiten, um die Reaktionsdauer abzukürzen. If you use low-boiling agents such as methyl or ethyl alcohol, it is expedient, under pressure at above the boiling point of the agent used Temperatures to work to shorten the reaction time.
