Description
Verfahren zur Herstellung eines Anthrachinonabkömmlings. Es wurde gefunden, dass ein wertvoller Anthrachinonabkömmling hergestellt werden kann, wenn man ein in 2-Stellung einen aus tauschbaren Substituenten enthaltendes 1 Amino-4-anilido-anthra.chinon mit Mitteln behandelt, die den austauschbaren Substi- tuenten durch eine Merkaptogruppe zu erset zen imstande sind, und hierauf mit Mitteln, die die f-Oxyäthylgrup,pe einzuführen im stande sind.
Der neue= Anthrachinonabkömmling, der 1- Amino - 4 - anilido - anthrachinon -i 2-(ss-ogy- #tthyl)-thioäther, ist ein dunkelblaues Pulver, das sich in konzentrierter Schwefelsäure mit schmutzig violetter und in Aceton mit blauer Farbe löst und Acetatkunstseide in kräftigen und lichtechten blauen Tönen färbt. Der neue Stoff kann auch als Zwischenprodukt Ver wendung finden.
Die als Ausgangsstoffe verwendeten 1- Amino-4-a.nili:do-a.nthra.chinone können als austauschbaren Substituenten in 2-Stellung beispielsweise ein Halogenatom, insbesondere ein Bromatom, oder eine Sulfonsäuregruppe enthalten. Als Mittel, die den austauschbaren Substituenten durch eine Merkaptogruppe zu ersetzen imstande sind, kommen beispiels weise Schwefelalkalien in Betracht, und zur Einführung der ss-Ogyäthylgruppe ist bei spielsweise Äthylenchlorhydrin brauchbar.
Die Durchführung der Reaktion kann in an sich bekannter Weise zum Beispiel in alkolIolischem. wänserigem oder gemischt a1- koholisch-wässerigem Medium, offen oder unter Druck vorgenommen werden.
<I>Beispiel:</I> <B>100</B> g 1-Amino-4-anilido-2-bromanthrachi- non werden. zusammen mit 300 cm3 Methyl alkohol, 75 cm' Wasser, 0,75 g Soda, 200 cms Natriumsulfhydratlösung mit einem Gehalt an 24,6 Vol.- % + 3,6 % Nass, 100 em3 40- vol.- %iger Natronlauge und 50 g Schwefel 5 Stunden in einem Eisenautoklaven auf 90 erhitzt.
Man destilliert den Alkohol ab, spült mit 400 cm3 1%iger Sodalösung nach, fällt das Merkaptan mit 200 g Kochsalz aus, kühlt wenn nötig auf 10 bis 15 und filtriert. Das Filtrat ist nur .schwach gefärbt, aber nicht mehr blau. Man wäscht mit 800 cm' einer Lösung von 20'% Kochsalz und 1 Soda frei von S-Ionen (Probe mit Bleiacetat).
Hierauf wird das Merkaptan sofort in <B>1000</B> cm3 1%iger Sodalösung mit 22 cm3 Äthylenchlorhydrin erwärmt, bis die Lösung farblos. wird (bei etwa 70 ), worauf man fil triert und mit Wasser kalt auswäscht.
Process for the preparation of an anthraquinone derivative. It has been found that a valuable anthraquinone derivative can be produced if a 1-amino-4-anilido-anthraquinone containing one of exchangeable substituents in the 2-position is treated with agents which replace the exchangeable substituent with a mercapto group are able, and then with means that the f-Oxyäthylgrup, PE are able to introduce.
The new = anthraquinone derivative, the 1- amino - 4 - anilido - anthraquinone -i 2- (ss-ogy- #tthyl) -thioether, is a dark blue powder that dissolves in concentrated sulfuric acid with a dirty purple color and in acetone with a blue color and acetate artificial silk in strong and lightfast blue tones. The new substance can also be used as an intermediate product.
The 1-amino-4-a.nili: do-a.nthra.chinones used as starting materials can contain, for example, a halogen atom, in particular a bromine atom, or a sulfonic acid group as exchangeable substituents in the 2-position. As means that are able to replace the exchangeable substituent by a mercapto group, for example, alkaline sulfur come into consideration, and for example, ethylene chlorohydrin can be used to introduce the ß-Ogyäthylgruppe.
The reaction can be carried out in a manner known per se, for example in alcoholic. aqueous or mixed alcoholic-aqueous medium, open or under pressure.
<I> Example: </I> <B> 100 </B> g of 1-amino-4-anilido-2-bromoanthraquinone. together with 300 cm3 of methyl alcohol, 75 cm of water, 0.75 g of soda, 200 cms of sodium sulfhydrate solution with a content of 24.6% by volume + 3.6% wet, 100 em3 of 40% by volume sodium hydroxide solution and 50 g of sulfur heated to 90 in an iron autoclave for 5 hours.
The alcohol is distilled off, rinsed with 400 cm3 of 1% soda solution, the mercaptan is precipitated with 200 g of table salt, cooled to 10 to 15 if necessary and filtered. The filtrate is only slightly colored, but no longer blue. It is washed with 800 cm 'of a solution of 20% common salt and 1 soda free of S ions (sample with lead acetate).
The mercaptan is then immediately heated in <B> 1000 </B> cm3 1% soda solution with 22 cm3 ethylene chlorohydrin until the solution is colorless. (at about 70), whereupon you filter and wash with cold water.
