Description
Verfahren zur Herstellung eines neuen Farbstoffes. Es wurde gefunden, dass ein neuer Farb stoff entsteht, wenn man 1-Amino-4-nitro- # a nthrachinan diazotiert, hierauf mit 1.-Phe- nyl-3-methyl-5-pyrazolon kuppelt and das so erhaltene Produkt mit Reduktionsmitteln behandelt.
Der neue Farbstoff bildet ein dunkel violettes Pulver, das sich in konzentrierter I ehwefelsäure mit gelbbrauner und in Toluol mit violettroter Farbe löst. Er färbt die Aceta,tseide in reinen rötlielivioletten Tö nen an.
<I>Beispiel:</I> <B>13,5</B> Teile 1-Amino-4-nitroanthrachinoTt werden in der zehnfaehen Menge Schwefel säure gelöst, bei<B>10</B> bis 20<B>'</B> mit<B>3,6</B> Teilen Natriumnitrit versetzt und 48 Stunden bei Zimmertemperatur gerührt.
Die so erhaltene Lö,%,ung wird auf 400 Teile Eis ausgetragen, der kristallin ab- cileselliedene Diazokörper abgesaugt und mit einer zirka, 40 '/oigen Schwefelsäure ge waschen. Der Diazakörper wird hierauf in <B>8,00</B> Teilen Eiswasser gelöst, von eventuellen unlöslichen Anteilen abfiltriert und mit einer Lösung von<B>6</B> Teilen 1-Plienyl-3-methyl- 5-pyrazolo-n in 200 Teilen Wasser,<B>100</B> Tei len Eis und 20 Teilen Natriumearbonat ver einigt.
Nach mehrstündigem Rühren -wird abgesaugt und neutral gewaschen. Der so hergestellte Nitroazokörper bildet getrocknet ein rotbraunes Pulver, das sieh in konzen trierter Sehwefelsäure orange, in Tolual braunorange, löst.
Die feuchte Paste des Nitrokörpers wird nun mit 200 Teilen Wasser verrührt und mit<B>15</B> Teilen Natriumsulfliydrat während einer halben bis einer Stunde bei<B>60'</B> nicht übersteigender Temperatur behandelt. Hier auf wird abgesaugt, neutral gewaschen und gegebenenfalls in bekannter Weise ver- pastet. <B>-</B>
Process for the production of a new dye. It has been found that a new dye is produced when 1-amino-4-nitro- # a nthraquinane is diazotized, then coupled with 1.-phenyl-3-methyl-5-pyrazolone and the product thus obtained with reducing agents treated.
The new dye forms a dark purple powder which dissolves in concentrated sulfuric acid with a yellow-brown color and in toluene with a purple-red color. He colors the Aceta, silk in pure reddish violet tones.
<I> Example: </I> <B> 13.5 </B> parts of 1-amino-4-nitroanthraquinone are dissolved in ten times the amount of sulfuric acid, at <B> 10 </B> to 20 <B> '</B> mixed with <B> 3.6 </B> parts of sodium nitrite and stirred for 48 hours at room temperature.
The solution obtained in this way is poured onto 400 parts of ice, and the crystalline ab- cileselliedene diazo body is filtered off with suction and washed with about 40% sulfuric acid. The diazo body is then dissolved in <B> 8.00 </B> parts of ice water, any insoluble constituents are filtered off and treated with a solution of <B> 6 </B> parts of 1-plienyl-3-methyl-5-pyrazolo- n in 200 parts of water, <B> 100 </B> parts of ice and 20 parts of sodium carbonate combined.
After several hours of stirring, it is filtered off with suction and washed neutral. The nitroazo body produced in this way forms a red-brown powder when dried, which dissolves orange in concentrated sulfuric acid and brown-orange in tolual.
The moist paste of the nitro body is then stirred with 200 parts of water and treated with <B> 15 </B> parts of sodium sulfide hydrate for half an hour to one hour at a temperature not exceeding 60 °. Here it is suctioned off, washed neutral and, if necessary, pasted in a known manner. <B> - </B>
