Description
Verfahren zur Herstellung eines Rüpenfarbstofes. Es wurde gefunden, dass ein Küpenfarb- stoff hergestellt werden kann, wenn man 1 Mol Thianthrendicarbonsäure oder eines ihrer funktionellen, Derivate, die ,die Carbogyl- gruppen bezw. Carbogylderivatgruppen an denselben Stellen im Thianthrenmolekül ent hält,
die die Bromatome im Dibromthianthren einnehmen, dass durch Bromieren von Thi- anthren in Nitrobenzol erhalten. wird, mit <B>2</B> Mol 1-Aminoanthrachinon umsetzt.
Der neue Farbstoff isit ein gelbes Pulver, ,das mit viodettb@rauner Farbe verküpt und Baumwolle in echten, gelben Tönen. färbt.
Zur Durchführung der Umsetzung kann die Thianthrendicarbansäure oder vorzugs weise eines ihrer reaktionsfähigen Derivate, beispielsweise das Säurechlorid, verwendet werden. Die Umsetzung erfolgt vorzugsweise in einem indifferenten Verteilungs- oder Lösungsmittel, insbesondere solchen von höherem Siedepunkt, wie Chlorbenzol, Nitro- benzo,1 oder Dichlorbenzol,
und bei erhöhter Temperatur, in An- oder Abwesenheit säure- bindendex sowie katalytisch wirkender Mittel. Die nachdem vorliegenden Verfahren als Ausgangsstoff verwendete Thianthrendicar- bonsäure kann,
in folgender Weise erhalten werden 216 Teile Thianthren werden. in 800 Tei len Nitrobenzol verteilt. Man<B>'MM</B> bei Zim- mertemperatur langsam eine Mischung von 336 Teilen Brom und 100 Teilen Nitrobenzol zutropfen. Nach mehrtägigem. Ruhren. bei Zimmertemperatur hat .die Bromwasserstoff- entwicklung nachgelassen.
Man saugt scharf ab, wäscht gründlich mit Alkohol nach und trocknet. Das so erhaltene Produkt ist ein weisses Pulver, das sich in. konzentrierter Schwefelsäure mit blauer Farbe löst. Der Analyse nach liegt ein Dibromthian@thren vor.
30 Teile des im vorhergehenden Absatz beschriebenen Dibramthianthrens werden zu sammen mit 16 Teilen Cuprooyanid in 100 Teilen wasserfreiem Pyridin verteilt und im. Autosklaven 6 Stunden lang auf 250-255 erhitzt.
Nach dem Erkalten wird filtriert, der Rückstand mit Alkohol ausgewaschen, dann mit 30 % iger Salpetersäure kurze Zeit bei Zimmertemperatur verrührt, filtriert, ge waschen und getrocknet. Man erhält ein bräunliches, kristallines Pulver. Der Analyse nach liebt ein Thianthrendinitril vor.
23,4 Teile des im vorhergehenden AI:!satz beschriebenen Thia.nthrendinitrils werden zu sammen mit 10 Teilen Ätzkali in 6f_1(1 Teilen 96 % igem Alkohol verteilt und im Auto klaven 12 Stunden lang auf 180-185" erhitzt. Hierauf destilliert man den Alkohol möglichst vollständig ab, löst den Rückstand in Wasser, kocht mit etwas Tierkohle auf und filtriert..
Die klare Lösung wird hierauf zum Sieden erhitzt und bis zur congosauren Reaktion mit Salzsäure versetzt. Die so gefällte Thia.nthren- dicarbonsäure wird filtriert, mit Wasser ge waschen und getrocknet. Man erhält ein gelb lichweisses, sehr sehwerlösliches Pulver, das sich in konzentrierter Schwefelsäure mit roter Farbe löst.
<I>Beispiel,:</I> 3 Teile fein gepulverte Thia.nthrendicar- bonsäuie (siehe oben) werden in 200 Teilen o-Dichlorbenzol verteilt und nach Zufügen von 15 Teilen Thionylchlorid so lange auf 1411-18(-)" erwärmt, bis die Umwandlung in das ThianthiTndiiearbonsäuredichlorid restlo vollzogen ist.
1tfan destilliert das überschüs sige Thionylchlorid ab, fügt eine siedende Lösung von 4,5 Teilen l.-Aminoanthraehinon in ltio@ Teilen Pichlorbenzol hinzu und erhitzt. 1 Stunde zum Sieden. Nach dem Erkalten rird filtriert, zuerst mit Dichlorbenzol, dann finit Alkohol gewaschen und getrocknet.
Process for the preparation of a beet dye. It has been found that a vat dye can be produced if 1 mol of thianthrene dicarboxylic acid or one of its functional derivatives, the, the carbogyl groups, respectively. Contains carbogyl derivative groups at the same positions in the thianthrene molecule,
which the bromine atoms in dibromothianthrene occupy, obtained by brominating thianthene in nitrobenzene. is reacted with <B> 2 </B> moles of 1-aminoanthraquinone.
The new dye is a yellow powder, which viodettb @ rauner color and cotton in real, yellow tones. colors.
To carry out the reaction, thianthrendicarbanic acid or preferably one of its reactive derivatives, for example the acid chloride, can be used. The reaction is preferably carried out in an inert partitioning agent or solvent, in particular those with a higher boiling point, such as chlorobenzene, nitrobenzene, 1 or dichlorobenzene,
and at elevated temperature, in the presence or absence of acid-binding agents as well as catalytically active agents. The thianthrendicarboxylic acid used as starting material according to the present process can
216 parts of thianthrene will be obtained in the following manner. distributed in 800 parts of nitrobenzene. A mixture of 336 parts of bromine and 100 parts of nitrobenzene is slowly added dropwise at room temperature. After several days. Stir. The evolution of hydrogen bromide has decreased at room temperature.
One sucks off sharply, rinsed thoroughly with alcohol and dried. The product thus obtained is a white powder which dissolves in concentrated sulfuric acid with a blue color. According to the analysis, there is a dibromothian @ thren.
30 parts of the dibramthianthrene described in the preceding paragraph are distributed together with 16 parts of cuprooyanide in 100 parts of anhydrous pyridine and im. Car slaves heated to 250-255 for 6 hours.
After cooling, it is filtered, the residue is washed out with alcohol, then stirred for a short time with 30% nitric acid at room temperature, filtered, washed and dried. A brownish, crystalline powder is obtained. According to the analysis, a thianthrendinitrile prefers.
23.4 parts of the thia.nthrendinitrile described in the preceding AI:! Sentence are distributed together with 10 parts of caustic potash in 6f_1 (1 part of 96% alcohol and heated to 180-185 "for 12 hours in the car. This is then distilled Alcohol as completely as possible, dissolve the residue in water, boil with a little animal charcoal and filter ..
The clear solution is then heated to the boil and hydrochloric acid is added until the congo acid reaction occurs. The thia.nthrene dicarboxylic acid precipitated in this way is filtered, washed with water and dried. A yellow light-white, very visually soluble powder is obtained which dissolves in concentrated sulfuric acid with a red color.
<I> Example: </I> 3 parts of finely powdered Thia.nthrendicar- bonsäuie (see above) are distributed in 200 parts of o-dichlorobenzene and, after adding 15 parts of thionyl chloride, heated to 1411-18 (-) " until the conversion into the thianti thiocyanate dichloride is complete.
1tfan the excess thionyl chloride is distilled off, a boiling solution of 4.5 parts of 1.-aminoanthraehinone in 1tio @ parts of pichlorobenzene is added and the mixture is heated. 1 hour to simmer. After cooling, it is filtered, washed first with dichlorobenzene, then finitely alcohol and dried.
