Description
Verfahren zur Herstellung eines inthrachinonderivates. Gegenstand dieses Zusatzpatentes ist ein Verfahren zur Herstellung eines Anthrachi- nonderivates. Das Verfahren ist dadurch ge kennzeichnet, dass man das Kondensations produkt aus 1 Mol Tribrombenzol und 3 Mol 1-Amino-4-benzoylaminoanthrachinon mit sauren Kondensationsmitteln, z.
B. Chlorsul- fonsäure, konzentrierter Schwefelsäure, oder aluminiumchloridschwefliger Säure mit einem Zusatz von Kochsalz, gegebenenfalls in Gegenwart eines Katalysators behandelt und das Reaktionsprodukt gegebenenfalls nach oxydiert. Das so erhältliche Reaktionspro dukt stellt ein bordo-rotes Pulver dar, das sich in konzentrierter Schwefelsäure mit smaragdgrüner Farbe löst und aus dieser Lösung beim Verdünnen mit Wasser in bordo-roten Flocken ausfällt. Pflanzliche Fasern werden aus der Küpe in echten, kla ren Korinthtönen gefärbt.
<I>Beispiel:</I> 300 Gewichtsteile Chlorsulfonsäure wer den mit 0,5 Gewichtsteilen Kupferpulver ver rührt, auf 40' C erwärmt und dann 20 Ge- wichtsteile des Kondensationsproduktes aus 1 Mol Tribrombenzol mit 3 Mol 1-Amino-4- benzoylaminoanthrachinon (blaue Nadeln, die in kalter konzentrierter Schwefelsäure mit schwach grünlicher Farbe löslich sind) eingetragen.
Man lässt 5 Stunden bei 40' C rühren und giesst die Schmelze zunächst in konzentrierte Schwefelsäure, dann in Wasser, in dem man 5 Gewichtsteile Natriumbichro- mat gelöst hat. Hierauf wird auf<B>70'</B> C er wärmt und eine Stunde bei dieser Tempe ratur verrührt. Nach dem Abfiltrieren und Auswaschen erhält man eine bordo-rote Farbpaste, die sich leicht verküpen lässt. Baumwolle wird aus dieser Küpe in echten, klaren Korinthtönen gefärbt.
Der Farbstoff stellt ein bordo-rotes Pulver dar, das sich in konzentrierter Schwefelsäure mit smaragd grüner Farbe löst und aus dieser Lösung mit Wasser wieder in bordo-roten Flocken zu fällen ist.
Process for the production of an inthraquinone derivative. The subject of this additional patent is a process for the production of an anthraquinone derivative. The process is characterized in that the condensation product of 1 mole of tribromobenzene and 3 moles of 1-amino-4-benzoylaminoanthraquinone with acidic condensing agents, e.g.
B. chlorosulphonic acid, concentrated sulfuric acid, or aluminum chloride-sulfuric acid treated with an addition of common salt, optionally in the presence of a catalyst and the reaction product optionally after oxidized. The reaction product obtainable in this way is a red powder that dissolves in concentrated sulfuric acid with an emerald green color and precipitates from this solution in red flakes when diluted with water. Vegetable fibers are dyed in real, clear corinth shades from the vat.
<I> Example: </I> 300 parts by weight of chlorosulfonic acid are stirred with 0.5 parts by weight of copper powder, heated to 40 ° C. and then 20 parts by weight of the condensation product of 1 mole of tribromobenzene with 3 moles of 1-amino-4-benzoylaminoanthraquinone (blue needles, which are soluble in cold concentrated sulfuric acid with a slightly greenish color).
The mixture is stirred for 5 hours at 40 ° C. and the melt is first poured into concentrated sulfuric acid and then into water in which 5 parts by weight of sodium bichromate have been dissolved. It is then heated to <B> 70 '</B> C and stirred at this temperature for an hour. After filtering off and washing out, you get a bordo-red color paste that can easily be vat. Cotton is dyed from this vat in real, clear corinth shades.
The dye is a red powder that dissolves in concentrated sulfuric acid with an emerald green color and can be precipitated from this solution with water into red flakes.
