Description
Verfahren zur Herstellung eines sauren Wollfarbstoffes. Vorliegendes Patent bezieht sich auf ein Verfahren zur Herstellung eines sauren Wollfarbstoffes, dadurch gekennzeichnet, dass man die 1-Amino-4-bromanthrachinon-2-sul- fonsäure mit 3-Aminobenzyl-methyl-benzyl- amin kondensiert und das erhaltene Konden sationsprodukt mit einem sulfonierenden Mittel bis zum Eintritt einer Sulfogruppe behandelt.
Der so erhaltene Farbstoff löst sich in konzentrierter Schwefelsäure mit schmutzig blauvioletter Farbe, die auf Zusatz von Para- formaldehyd nach gelbstichig grün um schlägt, und färbt Wolle in klaren, rotstichig blauen Tönen von guter Lichtechtheit und guten Nassechtheiten. Er besitzt ein gutes Egalisierungsvermögen.
<I>Beispiel:</I> 100 Teile 1-Amino-4-bromanthrachinon- 2-:sulfonsäure werden in etwa 5200 Teilen Wasser gelöst und 100 Teile Natriumbicar- bonat, 10 Teile Kupfersulfat und eine Lösung von 66 Teilen 3 - Aminobenzyl - (methyl - benzyl)-amin zugesetzt. Die Reaktions- mischung wird mehrere Stunden zum Sieden erhitzt und das gebildete Kondensations produkt durch Ansäuern abgeschieden.
Es wird abgesaugt und mit Wasser ausge waschen, bis das Filtrat farblos abläuft, und getrocknet.
30 Teile des obigen Kondensationsproduk- tes werden in einem Gemisch aus 300 Teilen Schwefelsäure-Monohydrat und 30 Teilen 20%igem Oleum gelöst. Die Reaktionsmasse wird ungefähr 20 Stunden auf 40-45' C er wärmt und denn. mit Eis versetzt. Die stark mineralsaure Farbstofflösung wird nun mit Natronlauge von 33'B6, zweckmässig unter äusserer Kühlung, neutralisiert, wobei sich der gebildete Farbstoff ausscheidet.
Er wird abgesaugt und mit Salzwasser von<B>15'B6</B> nachgewaschen.
Process for the production of an acidic wool dye. The present patent relates to a process for the production of an acidic wool dye, characterized in that the 1-amino-4-bromoanthraquinone-2-sulphonic acid is condensed with 3-aminobenzyl-methyl-benzyl amine and the resulting condensation product is condensed with a treated sulfonating agent until a sulfo group occurs.
The dye thus obtained dissolves in concentrated sulfuric acid with a dirty blue-violet color, which turns yellowish green on addition of paraformaldehyde, and dyes wool in clear, reddish blue shades of good lightfastness and good wet fastness properties. He has a good ability to equalize.
<I> Example: </I> 100 parts of 1-amino-4-bromoanthraquinone-2-: sulfonic acid are dissolved in about 5200 parts of water and 100 parts of sodium bicarbonate, 10 parts of copper sulfate and a solution of 66 parts of 3 - aminobenzyl - (methyl - benzyl) amine added. The reaction mixture is heated to the boil for several hours and the condensation product formed is separated off by acidification.
It is filtered off with suction and washed out with water until the filtrate runs colorless, and dried.
30 parts of the above condensation product are dissolved in a mixture of 300 parts of sulfuric acid monohydrate and 30 parts of 20% strength oleum. The reaction mass is about 20 hours at 40-45 'C he warms and then. mixed with ice. The strongly mineral acid dye solution is then neutralized with sodium hydroxide solution of 33'B6, expediently with external cooling, whereby the dye formed is precipitated.
It is suctioned off and washed with <B> 15'B6 </B> salt water.
