Zusatz zum Patente 175067 vom 6. April 1905.Addendum to patent 175067 of April 6, 1905.
Patentiert im Deutschen Reiche vom 31. Juli 1908 ab. Längste Dauer: 5. April 1920.Patented in the German Empire on July 31, 1908. Longest duration: April 5, 1920.
In dem Patent 175067 sowie in dem Zusatzpatent 211927 ist ein Verfahren beschrieben, nach dem 2 · 2' - Dimethyldianthrachinonyl oder dessen Derivate durch Erhitzen für sich oder bei der Behandlung mit wasserentziehenden Mitteln in neue 'Verbindungen übergeführt werden, welche die Eigenschaften von Küpenfarbstoffen besitzen (vgl. Patent 174494).In the patent 175067 and in the additional patent 211927 a method is described, after the 2 · 2 '- dimethyldianthraquinonyl or its derivatives by heating for itself or with after treatment with dehydrating agents are converted into new 'compounds, which have the properties of vat dyes (see patent 174494).
Es wurde nun gefunden, daß man dieses Verfahren in vorteilhafter Weise derart ausführen kann, daß man die genannten Verbindungen mit Wasser mit oder ohne Zusatz von Ammoniak oder Salzen erhitzt.It has now been found that this process can be carried out in an advantageous manner can that the compounds mentioned are heated with water with or without the addition of ammonia or salts.
Das Verfahren verläuft außerordentlich glatt und hat dabei den Vorteil größter Einfachheit.The process is extremely smooth and has the advantage of great simplicity.
Eine 5- bis ioprozentige wässerige Paste von 2 · 2' - Dimethyl -1 · 1' - dianthrachinonyl wird in einem geschlossenen Gefäß während 10 bis 12 Stunden auf 230 ° bis 250 ° erhitzt. Das Reaktionsprodukt ist identisch mit dem in den Beispielen 1 bis 3 des Hauptpatents beschriebenen Körper.A 5 to 10 percent aqueous paste of 2 · 2 '- dimethyl -1 · 1' - dianthraquinonyl is kept in a closed vessel during Heated to 230 ° to 250 ° for 10 to 12 hours. The reaction product is identical to that in Examples 1 to 3 of the main patent described body.
An Stelle von Wasser kann man auch wässeriges Ammoniak, Salzlösungen usw. verwenden, ferner kann das 2 · a'-Dimethyl-i · 1'-dianthraehinonyl durch seine Derivate ersetzt werden..Instead of water, you can also use aqueous ammonia, salt solutions, etc. furthermore, the 2 · a'-dimethyl-i · 1'-dianthraehinonyl be replaced by its derivatives ..
