Description
Verfahren zur Herstellung eines ehromierbaren Azofarbstoffes. Gegenstand vorliegenden Patentes ist ein Verfahren zur Herstellung eines chromier- baren Azofarbstoffes. Das Verfahren ist da durch gekennzeichnet, dass dianotiertes 6-Ni- t.ro-2-amino-4-methyl-l-oxy-benzol mit 4-Me- thyl-l-oxy-naphthalin-8-sulfonsäure in alkali schem Medium vereinigt. wird. Der Chrom komplex des neuen Farbstoffes stellt ein grau schwarzes Pulver dar, das Wolle aus ameisen saurem Bade in klaren, grünstickig grauen Tönen von hervorragender Egalität färbt.
Die Färbungen besitzen eine vorzügliche Abendfarbe.
<I>Beispiel:</I> 16,8 Teile 6-Nitro-2-amino-4-methyl-l-oxy- benzol werden dianotiert und die Acidität mit Natriumbicarbonat auf kongoviolette Reak tion eingestellt. Die Diazoverbindung giesst man in eine Lösung von 27,3 Teilen 4-methyl- 1.-oxy-naphthalin-8-sulfonsaurem Natrium in 400 Teilen Wasser, 10 Teilen wasserfreiem Natriumcarbonat und 26 Teilen Pyridin. Nach wenigen Stunden ist die Farbstoff bildung beendet. Man erwärmt auf 60 , saugt den schön kristallin ausgefallenen Farbstoff ab.
Der Chromkomplex des Farbstoffes kann. erhalten werden, indem man obigen Farbstoff in 1000 Teilen Wasser verrührt, 240 Teile einer Lösung von chromsalicylsaurem Ammo nium, entsprechend 9,1 Teilen Chromoxyd zugibt und dann während 25 Stunden zum Sieden erhitzt. Man gibt 40 Teile Kochsalz zu, filtriert noch heiss die Chromkomplexver- bindung ab und trocknet sie. Man erhält so ein Lyrausehwarzes Pulver.
Process for the production of an honorable azo dye. The subject of the present patent is a process for the production of a chromable azo dye. The process is characterized in that dianotated 6-nitro-2-amino-4-methyl-1-oxy-benzene with 4-methyl-1-oxy-naphthalene-8-sulfonic acid in an alkaline medium united. becomes. The chrome complex of the new dye is a gray-black powder that dyes wool from an acidic bath in clear, greenish-gray tones of excellent levelness.
The colorations have an excellent evening color.
<I> Example: </I> 16.8 parts of 6-nitro-2-amino-4-methyl-1-oxybenzene are dianotized and the acidity is adjusted to a congoviolet reaction with sodium bicarbonate. The diazo compound is poured into a solution of 27.3 parts of 4-methyl-1.-oxy-naphthalene-8-sulfonic acid sodium in 400 parts of water, 10 parts of anhydrous sodium carbonate and 26 parts of pyridine. After a few hours, the dye formation has ended. The mixture is heated to 60 and the dyestuff which has precipitated out in a beautiful crystalline manner is filtered off with suction.
The chromium complex of the dye can. be obtained by stirring the above dye in 1000 parts of water, 240 parts of a solution of chromsalicylic acid ammonium, corresponding to 9.1 parts of chromium oxide and then heated to the boil for 25 hours. 40 parts of common salt are added, the chromium complex compound is filtered off while it is still hot and it is dried. A lyre-black powder is obtained in this way.
