Description
Zusatzpatent zum Hauptpatent Nr. 221927. Verfahren zur Herstellung eines primären Disazofarbstoffes. Vorliegendes Patent bezieht sich auf ein Verfahren zur Herstellung eines primären Disazofarbstoffes, dadurch gekennzeichnet, dass man :die Diazoverbindung von 1-Amino- 2,4-dichlorbenzol in saurem Medium mit 1- Amino-:8-oxynaphthalin-3,6-:disulfonsäureund den so erhaltenen Monoazofarbstoff in alka: lischem Medium mit :
der Diazoverbindung aus 1-Amino-4-N-eyclohexyl-caprinyl-amino- benzol vereinigt.
Der so erhaltene Disazofarbstoff ist ein dunkles Pulver, :das sich in Wasser mit blauer, in konzentrierter .Schwefelsäure mit rotstichig schwarzer Farbe löst, und färbt Wolle aus saurem Bade in schwarzen Tönen. Die Färbungen besitzen sehr gute Wasch-, Walk-, Schweiss-, Seewasser-, Dekatur- und Lichtechtheit.
Beispiel: Eine aus 16,2 Teilen 1-Amino-2,4-diohlor- Benzol hergestellte Diazolösung lässt man in eine mineralsaure Lösung von 3,1,9 Teilen 1- Amino-:8-oxynaphthaIin-3, 6-:disulfonsäurelau- fen. Nach beendeter Bildung des Monoazo- fa.rbstoffes wird dieser abgeschieden und mit überschüssigem Natriumcarbonat wieder in Lösung gebracht.
In diese Lösung lässt man eine aus 34,4 Teilen 1-Amino-4-N-:cyclohexyl- caprinyl - amino#benzol hergestellte Dia.zo- lösung fliessen. Der Disazofarbs;to:ff wird ab geschieden, gewaschen und getrocknet.
Additional patent to main patent No. 221927. Process for the production of a primary disazo dye. The present patent relates to a process for the preparation of a primary disazo dye, characterized in that: the diazo compound of 1-amino-2,4-dichlorobenzene in an acidic medium with 1-amino-: 8-oxynaphthalene-3,6-: disulfonic acid and the monoazo dye thus obtained in alkaline medium with:
the diazo compound from 1-amino-4-N-cyclohexyl-caprinyl-aminobenzene combined.
The disazo dye obtained in this way is a dark powder, which dissolves in water with a blue color, in concentrated sulfuric acid with a reddish black color, and dyes wool from an acid bath in black tones. The dyeings have very good wash, fulling, perspiration, seawater, decatur and lightfastness.
Example: A diazo solution prepared from 16.2 parts of 1-amino-2,4-diochlorobenzene is allowed to pour into a mineral acid solution of 3.1.9 parts of 1- amino-: 8-oxynaphthaIin-3, 6-: disulfonic acid lau- fen. When the formation of the monoazo dye has ended, it is separated out and redissolved with excess sodium carbonate.
A dia.zo solution prepared from 34.4 parts of 1-amino-4-N-: cyclohexyl-caprinyl-amino-benzene is allowed to flow into this solution. The disazofarbs; to: ff is separated, washed and dried.
