Zusatz zum Patent JU 46252 vom 13. Januar i<Addition to patent JU 46252 from January 13th i <
Patentirt im Deutschen Reiche vom 20. Dezember 1888 ab. Längste Dauer: 12. Januar 1903.Patented in the German Empire on December 20, 1888. Longest duration: January 12, 1903.
In dem Haupt - Patent Nr. 46252 ist ein neues Verfahren zur Darstellung von gelben, orangerothen bis braunen ,Farbstoffen beschrieben, darin bestehend, dafs man oxydable Substanzen auf p-Nitrotoluolsulfosäure und Alkalien in der Wärme einwirken läfst.In the main patent no. 46252 a new method for the representation of yellow, orange-red to brown, dyes are described, consisting in the fact that one can oxidize substances to act on p-nitrotoluenesulfonic acid and alkalis in the heat.
Im Haupt-Patent ist eine Anzahl von oxydablen Körpern aufgezählt, welche bei Ausführung des obigen Verfahrens besonders geeignet erscheinen. In Folgendem werden noch einige solcher Substanzen genannt, welche, in das im Haupt-Patent charakterisirte Verfahren substituirt, einen gleichen oder ähnlichen Effect wie die dort namhaft gemachten Substanzen hervorbringen: Lävulinsäure, xanthogensaure Salze, Amidophenol, Oxydiphenylamine und deren Homologen, Oxyphenylnäphtylamine, Kohlehydrate, z. B. Stärke, Dextrin, Zucker.The main patent enumerates a number of oxidizable bodies which are particularly suitable when carrying out the above method appear. In the following some such substances are mentioned which, in the process characterized in the main patent substitutes an identical or similar effect how the substances named there produce: levulinic acid, xanthogenic acid Salts, amidophenol, oxydiphenylamines and their homologues, oxyphenylnaphthylamines, Carbohydrates, e.g. B. starch, dextrin, sugar.
1. 30 kg p-nitrotoluolsulfosaures Natron werden mit 160 1 Wasser, 60 kg Lauge von 400B. und 15 kg Lävulinsäure bis zur beendeten Farbstoffbildung gekocht. Der Farbstoff wird mit Kochsalz und Essigsäure abgeschieden. Er färbt orange.1. 30 kg of p-nitrotoluolsulfosaures soda are boiled with 160 1 of water, 60 kg of liquor 40 0 B. and 15 kg of levulinic acid to the finished dye formation. The dye is deposited with common salt and acetic acid. It turns orange.
2. 40 kg p-nitrotoluolsulfosaures Natron werden mit 150 1 Wasser, 50 kg Lauge von 400 B. und 20 kg xanthogensaurem Kali gekocht. Der. Farbstoff wird wie im vorhergehenden Beispiel abgeschieden und färbt orange.2. 40 kg of p-nitrotoluolsulfosaures soda are mixed with 150 1 of water, 50 kg of liquor 40 0 B. 20 kg xanthogensaurem Kali cooked. Of the. Dye is deposited as in the previous example and turns orange.
3. 50 kg p-nitrotoluolsulfosaures Natron werden mit 150 1 Wasser, 15 kg m-Oxydiphenylamin und 50 kg Lauge (400 B.) mehrere Stunden gekocht, bis die Farbstoff bildung beendet ist. . Man setzt alsdann 15 kg Salmiak zu, kocht auf, salzt aus, filtrirt und trocknet. Der Farbstoff färbt braun.3. 50 kg of p-nitrotoluolsulfosaures soda are mixed with 150 1 of water, 15 kg of m-Oxydiphenylamin 50 kg liquor (40 0 B.) cooked for several hours, until the dye completed education. . 15 kg of ammonia are then added, the mixture is boiled, salted out, filtered and dried. The dye turns brown.
Statt m-Oxydiphenylamin lassen sich in ähnlicher Weise entsprechende Mengen ρ-Oxy-' diphenylamin, Oxyphenyltolylamin oder Oxyphenylnaphtylamin verwenden.Instead of m-oxydiphenylamine can be used in a similar Corresponding amounts of ρ-oxy- 'diphenylamine, oxyphenyltolylamine or oxyphenylnaphtylamine use.
4. 25 kg p-nitrotoluolsulfosaures Natron werden mit 100 1 Wasser, 5 kg Amidophenol und 25 kg Lauge von 400 B. längere Zeit gekocht. Der Farbstoff wird in üblicher Weise abgeschieden; er färbt braun.4. 25 kg p-nitrotoluolsulfosaures soda are boiled with 100 1 water 5 kg and 25 kg liquor amidophenol 40 0 B. longer time. The dye is deposited in the usual way; it turns brown.
5. 50 kg p-nitrotoluolsulfosaures Natron, 6001 Wasser, 50 kg Lauge von 400 B., 30 kg Dextrin werden längere Zeit unter zeitweisem Ersatz des verdampfenden Wassers zusammen gekocht. Wenn die Farbintensität nicht mehr zunimmt, neutralisirt man mit Essigsäure, salzt aus, filtrirt, prefst und trocknet. Der resultirende Farbstoff färbt gelborange.5. Add 50 kg of p-nitrotoluolsulfosaures soda, water 6001, 50 kg of liquor 40 0 B., 30 kg dextrin are cooked for longer periods under occasional replacement of the evaporating water together. When the intensity of the color no longer increases, neutralize with acetic acid, salt out, filter, prefix and dry. The resulting dye turns yellow-orange.
Eben solche gelborange färbende Farbstoffe werden erhalten, wenn in obigem Recept anstatt 30 kg Dextrin und 50 kg Lauge einmal 30" kg Fruchtzucker, 50 kg Lauge und zum anderen 50 kg Stärke und 60 kg Lauge zur Verwendung kommen.Such yellow-orange coloring agents are obtained if in the above recipe instead 30 kg of dextrin and 50 kg of lye, once 30 "kg of fructose, 50 kg of lye and, on the other hand, 50 kg of starch and 60 kg of lye Use come.
