bei der Umsetzung sich abspaltenden Rest bedeutet.
Als abspaltbare Reste X kommen Halogen atome, Hydroxyl-, Merkapto-, Amino-, Al- koxy- und A1kylmerkaptograppen sowie quartäre Ammoniumgruppen in Betracht.
Es wurde nun gefunden, dass man eben falls einen wertvollen Küpenfarbstofferhält, wenn man das im Hauptpatent beschriebene
EMI0001.0041
Pyrazinoanthrachinon <SEP> mit <SEP> 2,-Chlor-3-toluidin
<tb> umsetzt.
<tb>
Die <SEP> Umsetzung <SEP> kann <SEP> man <SEP> durch <SEP> Erhitzen

<tb>
Der <SEP> neue <SEP> Farbstoff <SEP> färbt <SEP> aus <SEP> orange brauner <SEP> Küpe <SEP> Baumwolle <SEP> in. <SEP> kräftig <SEP> gold orangen <SEP> Tönen, <SEP> die <SEP> vorzügliche <SEP> Echtheits eigenschaften <SEP> besitzen.
<tb>
<I>Beispiel <SEP> 1:</I>
<tb> 3,2! <SEP> Teile <SEP> Pz-Chloroxy-l.2-pyrazino anthmachinon <SEP> (erhältlich <SEP> aus <SEP> Pz-Dioxy=1 <SEP> . <SEP> 2 pyrazino-antbraehinon <SEP> durch <SEP> Erhitzen <SEP> mit

<tb> werden, <SEP> mit <SEP> 1,42 <SEP> Teilen <SEP> 2-Chlor-3-toluidin <SEP> in 40 Teilen Nitrobenzol so lange gekocht,
bis die @Salzsäureentwicklung beendet ist. Beim Erkalten des Reaktionsgemisches scheidet sich der Farbstoff in orangen Kristallen ab; durch Absaugen und Ausdämpfen wird er rein erhalten.
Er färbt aus orangebrauner Küpe Baum wolle kräftig goldorange.
Beispiel <I>2:</I> 10 Teile Pz-Dioxy-1.2-pyrazinoanth@ra- chinon werden mit 2 Teilen Zinkchlorid in 50 Teilen Nitrobenzol auf 1,80 bis<B>190'</B> C erhitzt, dann langsam 10 Teile 2-Chlor-3- toluidin eingetragen und so lange weiter er hitzt,
bis kein Dioxypyrazinoanthrachinon mehr nachzuweisen ist. Dann läBt man erkal ten, saugt ab und arbeitet wie in Beispiel 1 beschrieben auf. Man erhält denselben Farb stoff in sehr guter Ausbeute.
Beispiel <I>3:</I> 10 Teile des Pz-Oxy-amino -1.2-pyrazino- anthrachinons (erhältlich durch Einleitung von Ammoniak in eine auf<B>150'</B> C erhitzte Lösung von Pz-Chloroxy-1. 2-pyrazinoanthra- chinon in Nitrobenzol;
rotbraunes Pulver, das sich in Schwefelsäure mit brauner Farbe löst und ein gelbes Sulfat bildet), 10 Teile 2-Chlor-3-toluidin und 30 Teile Nitrobenzol erhitzt man etwa eine Stunde lang zum Sieden. Nach Erkalten saugt man den ausgeschie denen Farbstoff ab, wäscht ihn mit Alkohol und trocknet ihn.
Den Farbstoff erhält man auch, wenn man an Stelle des Pz-Oxy-amino-1.2-pyrazino- anthrachinons das Pz-Oxy-methylamino-1. 2- pyrazinoanthrachinon verwendet (herstellbar auf entsprechende Weise durch Verwendung von Methylamin an Stelle von Ammoniak;
gelbrote Nadeln, die in Schwefelsäure mit gelbroter Farbe löslich sind und ein gelbes Sulfat bilden), oder das Pz-Oxy-merkapto- 1 . 2-pyrazinoanthrachinon (herstellbar durch Umsetzen von Pz-Chloroxy-1.2-pyrazino- anthrachinon mit alkoholischem Natrium sulfid und Überführung des so erhaltenen Natriummerkaptids in das freie Merkaptan durch Behandeln mit Salzsäure;
rotbraunes Pulver, das sich in Alkohol mit rotvioletter Farbe löst) oder den daraus durch Methylieren mit Dimethylsulfat erhältlichen Thioäther oder das Pz-Oxy-äthoxy-1. 2-pyrazinoanthra- chinon (beispielsweise erhältlich durch Er hitzen von Pz-Chloroxy-1 . 2@-pyrazinoanthra- chinon mit alkoholischer Kaliumhydroxyd- lösung;
gelbe Nadeln aus Eisessig) oder das aus Pz-Chloroxy-1.2-pyrazinoanthrachinon durch gelindes Erwärmen mit Pyridin er hältliche Pyridiniumchlorid von der wahr scheinlichen Zusammensetzung

Process for the production of a vat dye. According to the main patent, a valuable vat dye is obtained if. one m-toluidine with a pyrazinoanthraquinone of the structure
EMI0001.0013
implements what. X one:
in the implementation means the remainder that is split off.
Halogen atoms, hydroxyl, mercapto, amino, alkoxy and alkyl mercapto groups and quaternary ammonium groups can be considered as the removable radicals X.
It has now been found that a valuable vat dye is also obtained by doing that described in the main patent
EMI0001.0041
Pyrazinoanthraquinone <SEP> with <SEP> 2, -chloro-3-toluidine
<tb> implements.
<tb>
The <SEP> implementation <SEP> can <SEP> man <SEP> by <SEP> heating
<tb>, the <SEP> <SEP> described above <SEP> in <SEP> over excess <SEP> 2-chloro-3rtoluidine <SEP> or <SEP> by <SEP> heating <SEP> the <SEP> calculated: <SEP> quantities <SEP> the <SEP> implementation participants <SEP> in <SEP> one. <SEP> suitable. Perform <SEP> solvent <SEP> @, <SEP> for <SEP> example <SEP> in
<tb> Presence <SEP> of <SEP> nitrobenzene. <SEP> Here <SEP> is <SEP> under
<tb> circumstances, the <SEP> addition <SEP> of a <SEP> condensation by means of <SEP> like <SEP> zinc chloride ,. <SEP> boric acid <SEP> or <SEP> one
<tb> Alkalibisulphates <SEP> bypassed.
<tb>
The <SEP> new <SEP> dye <SEP> colors <SEP> from <SEP> orange-brown <SEP> vat <SEP> cotton <SEP> in. <SEP> strong <SEP> gold-orange <SEP> tones, < SEP> which <SEP> have excellent <SEP> authenticity properties <SEP>.
<tb>
<I> Example <SEP> 1: </I>
<tb> 3.2! <SEP> parts <SEP> Pz-Chloroxy-1.2-pyrazino anthmachinon <SEP> (available <SEP> from <SEP> Pz-Dioxy = 1 <SEP>. <SEP> 2 pyrazino-antbraehinon <SEP> by < SEP> heating <SEP> with
<tb> Phosphorus oxychloride <SEP> in <SEP> nitrobenzene, <SEP> yellow-brown <SEP> needles <SEP> with <SEP> melting point <SEP> <B> 268 '</B> <SEP> C)
<tb>, <SEP> with <SEP> 1.42 <SEP> parts <SEP> 2-chloro-3-toluidine <SEP> in 40 parts nitrobenzene are boiled for so long
until the development of hydrochloric acid has ended. When the reaction mixture cools, the dye separates out in orange crystals; it is kept pure by suction and steaming.
He dyes tree wool from an orange-brown vat a strong golden orange.
Example <I> 2: </I> 10 parts of Pz-Dioxy-1.2-pyrazinoanth@raquinone are heated to 1.80 to 190 ° C with 2 parts of zinc chloride in 50 parts of nitrobenzene, then slowly added 10 parts of 2-chloro-3-toluidine and continued to heat
until no more dioxypyrazinoanthraquinone can be detected. Then it is allowed to cool, suctioned off and worked up as described in Example 1. The same dye is obtained in very good yield.
Example <I> 3: </I> 10 parts of Pz-oxy-amino -1.2-pyrazino-anthraquinone (obtainable by introducing ammonia into a heated to <B> 150 '</B> C solution of Pz-chloroxy- 1. 2-pyrazinoanthraquinone in nitrobenzene;
red-brown powder, which dissolves in sulfuric acid with a brown color and forms a yellow sulfate), 10 parts of 2-chloro-3-toluidine and 30 parts of nitrobenzene are heated to the boil for about an hour. After it has cooled down, suck off the discarded dye, wash it with alcohol and dry it.
The dye is also obtained if, instead of the Pz-oxy-amino-1,2-pyrazino-anthraquinone, the Pz-oxy-methylamino-1. 2-pyrazinoanthraquinone used (can be prepared in a corresponding manner by using methylamine instead of ammonia;
yellow-red needles, which are soluble in sulfuric acid with a yellow-red color and form a yellow sulfate), or the Pz-Oxy-merkapto- 1. 2-pyrazinoanthraquinone (can be produced by reacting Pz-chloroxy-1,2-pyrazinoanthraquinone with alcoholic sodium sulfide and converting the sodium mercaptide thus obtained into the free mercaptan by treatment with hydrochloric acid;
red-brown powder, which dissolves in alcohol with a red-violet color) or the thioether obtained from it by methylation with dimethyl sulfate or the Pz-oxy-ethoxy-1. 2-pyrazinoanthraquinone (obtainable, for example, by heating Pz-chloroxy-1. 2 @ -pyrazinoanthraquinone with alcoholic potassium hydroxide solution;
yellow needles from glacial acetic acid) or from Pz-chloroxy-1,2-pyrazinoanthraquinone by gentle heating with pyridine he obtainable pyridinium chloride of the probable composition
