Description
<B>Zusatzpatent</B> zum Hauptpatent Nr. 199465. Es wurde gefunden, @daB ein Farbstoff -der Anthrachinonreihe hergestellt werden kann, wenn,
man 1 Mol 1-Methylamiuo-4 halogen- anthraehinon auf 1 Mol 3-Aminopyren ein wirken lässt und in das erhaltene Produkt durch Behandlung mit einem sulfonierenden Mittel eine Sulfonsäuregruppe einführt.
Der erhaltene Farbstoff bildet ein elive- grünes Pulver, das sich in konzentrierter ,Schwefelsäure mit blauer Farbe löst und tie- rische Faser, wie z. B. Wolle, aus saurem Bade in kräftigen, sehr echten oli"vegTünen Tönen färbt.
Die Umsetzung wird zweckmässig in wäs- seriger oder alkoholisch wässervger Lösung unter Zusatz säurebindender Mittel, wie Na triumbikarbonat oder Natronlauge, und eines Katalysators, wie Kupferbronze oder eines Kupfersalzes, unter Erwärmen vorgenommen.
<I>Beispiel:</I> <B>7,6</B> Teile -1-Methylamino-4-bromanthra- chinan, 5,6 Teile 3-Aminopyren, hergestellt durch Mononitrieren und Reduzieren von Pyren, 4,6 Teile entwässertes Natriumacetat und 1 Teil Kupferacetat werden in 100 Tei len Amylalkohol während<B>10</B> Stunden bei einer Temperatur von 140 bis<B>150'</B> gerührt. Nach .dem Erkalten wird filtriert,
mit Alko hol ausgewaschen und der Rückstand zur Entfernung von Kupferverbindungen mit verdünnter Salosäure ausgekocht. Das Um setzungsprodukt bildet nach dem Auskochen mit Alkohol ein dunkelgefärbtes, schwarz grünes Pulver.
Eis wird mit 60 Teilen Sohwefeleäuremo@nohydrat 16 Stunden bei 50 bis 5,5 gerühmt, hierauf in Eias eingetragen, filtriert und ausgewaschen. Der Filterrück- stand wird dann in. verdünnter ;
Sadalösuug gelöst, von Verunreinigungen filtriert und das Filtrat mit Kochsalz versetzt, wobei: sich der Farbstoff abscheidet. Hierauf wird wie der filtriert, ausgewaschen und getrocknet.
<B> Additional patent </B> to main patent no. 199465. It has been found that a dye of the anthraquinone series can be produced if,
1 mole of 1-methylamino-4 halogenanthraehinone is allowed to act on 1 mole of 3-aminopyrene and a sulfonic acid group is introduced into the product obtained by treatment with a sulfonating agent.
The dye obtained forms an elive-green powder which dissolves in concentrated sulfuric acid with a blue color and produces animal fibers, e.g. B. Wool, from an acid bath, dyes in strong, very real olive green tones.
The reaction is expediently carried out in an aqueous or alcoholic aqueous solution with the addition of acid-binding agents, such as sodium bicarbonate or sodium hydroxide solution, and a catalyst, such as copper bronze or a copper salt, with heating.
Example: 7.6 parts -1-methylamino-4-bromoanthraquinane, 5.6 parts 3-aminopyrene, produced by mononitrating and reducing pyrene, 4.6 Parts of dehydrated sodium acetate and 1 part of copper acetate are stirred in 100 parts of amyl alcohol for <B> 10 </B> hours at a temperature of 140 to <B> 150 '</B>. After cooling down, it is filtered,
Washed out with alcohol and boiled the residue with dilute salic acid to remove copper compounds. The reaction product forms a dark-colored, black-green powder after boiling with alcohol.
Ice is boiled with 60 parts of Sohwefeleäuremo @ nohydrat for 16 hours at 50 to 5.5, then introduced into Eias, filtered and washed out. The filter residue is then diluted in;
Dissolved Sadalösuug, filtered from impurities and the filtrate is mixed with common salt, whereby: the dye separates. It is then filtered, washed and dried like that.
