Description

Verfahren zur Darstellung von Farbstoffen. Zusatz zum Patent 365902'" j. Durch das Hauptpatent 365902 und die Zusatzpatente 368168, 368169 und 368170 werden Verfahren zur,Darstellung von Farbstoffen geschützt, welche auf der Kondensation von in p-Stellung zum Azinstickstoff .durch Hvdroxvl substituierten Azinen mit 2 - 3-Dichlor-i # 4-chinonen oder ihren Substibubionsprodukten beruhen.Process for the representation of dyes. Addition to patent 365902 '"j. The main patent 365902 and the additional patents 368 1 68, 368169 and 368170 protect processes for the representation of dyes which are based on the condensation of azines with 2 - substituted in the p-position to the azine nitrogen. 3-dichloro-i # 4-quinones or their substitution products are based.

Es wurde nun gefunden, daß man die gleichen oder ähnliche Farbstoffe erhält, wenn man 2 - 3-Dichlor-i # q.-chinone idlurch 2-Chlori - q.-chinone oder ihre Sulibstitutionsprodukte ersetzt. Die Reaktion begünstigt man vorteilhaft durch Zusatz von Oxydationsmitteln oder Durchleiten von Luft.It has now been found that the same or similar dyes can be used obtained when 2 - 3-dichloro-i # q.-quinones idl by 2-chloro-q.-quinones or replaced their Sulibstitution products. The reaction is favorably favored by Adding oxidizing agents or passing air through.

Beispiel i.Example i.

5 Teile Eurhodol aus 2-Oxy-i - 4.-naphthochinon und i # 2-Diaminoberrrzol werden mit 4. Teilen 2-Chlor-i # 4-naphthochinon, 2 Teilen entwässertem Natriumacetat und ioo Teilen hTitrobenzol unter Rühren. und Durchleiten von Luft .eine Stunde auf 120 bis 130° erhitzt. Nach dem Erkalten wird der gebildete Farbstoff alagesatugt, der Rest wird durch Abblasen des Nitrobenzols gewonnen. Das gelbe Pulver des Farbstoffs löst sich in konz. Schwefelsäure bräunlich orangerot. Aus der orangefarbigen Küpe wird Baumwolle chlor-und seiifenecht gelb gefärbt.5 parts of Eurhodol from 2-Oxy-1-4-naphthoquinone and i # 2-Diaminoberrrzol with 4. parts of 2-chloro-i # 4-naphthoquinone, 2 parts of dehydrated sodium acetate and 100 parts of h-nitrobenzene with stirring. and passing air through .one hour heated to 120 to 130 °. After cooling, the dye formed is absorbed, the rest is obtained by blowing off the nitrobenzene. The yellow powder of the dye dissolves in conc. Sulfuric acid brownish orange-red. From the orange vat cotton is dyed yellow in a chlorine- and soap-proof manner.

Das Durchleiten der Luft durch das Reaktionsgemisch kann unterbleiben, wenn man 6 Teile subfirni-ertes Eisenchlorid dem Ansatz zufügt.The passage of air through the reaction mixture can be omitted, if you add 6 parts of subfined iron chloride to the batch.

B.eispi e1 2.B.eispi e1 2.

5 Teile des im Beispiel i verwendeten Eurhodols werden mit 2 Teilen 2,- 5=Dichlori - . -benizochinon, 2 Teilen entwässertem Natriu:macetat und 16o Teilen Nitrobenzol unter Rühren und Durchleiten von Luft eine .Stunde auf 12o° erhitzt. Nach Odem Erkalten wird abgesaugt. Der Farbstoff bildet ein olivegraues Pulver, das sich in konz. Schwefelsäure rot löst und aus der roten .Hydrosulfitküpe Baumwolle dunkelgrün anfärbt. Diese Färbung ,geht bei längerem Liegen an der Luft oder beim Behandeln mit Chlor in Braungelb über. Der Farbstoff ist anscheinend identisch mit demjenigen,des Beispiels 2 ,des Patents 368170. 5 parts of the Eurhodol used in Example i with 2 parts 2, - 5 = dichloro -. -benizoquinone, 2 parts of dehydrated sodium: macetate and 16o parts of nitrobenzene heated to 120 ° for one hour while stirring and passing air through. After the breath has cooled down, suction is performed. The dye forms an olive-gray powder, which is in conc. Sulfuric acid dissolves red and dyes cotton dark green from the red hydrosulfite vat. This color changes to brownish-yellow when lying in the air for a long time or when treated with chlorine. The dye appears to be identical to that of Example 2 of Patent 368170.
