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-srul- fonsäure mit 4-Amino-phenetidyl--diäthyl- 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 brünstichig blauer Farbe, die sich auf Zusatz von Para- formaldehyd nicht merklich ändert. Er färbt Wolle in klaren, ;rünstichi-g blauen Tönen von guter Lichtechtheit und besitzt ein her vorragendes Egalisierungsvermö.gen.
<I>Beispiel:</I> 100 Teile 1-Amino-4-bromanthrachinon-2- sulfonsäure werden in einem Gemisch von 5200 Teilen Wasser und 1800 Teilen Alkohol gelöst und mit<B>63</B> Teilen 4-Amino-pheneti- dyl-diäthylamin, 100 Teilen Natriumbicarbo- nat und 10 TeilenKupferchlorür versetzt. Die Reaktionslösung wird mehrere Stunden zum Sieden erhitzt, und das gebildete Reaktions produkt durch Ansäuern abgeschieden. Es wird abgesaugt und mit heissem Wasser gut ausgewaschen.
80 Teile des obigen Kondensationsproduk- tes werden in einem Gemisch aus 800 Teilen Schwefelsäure-Monohydrat und 80 Teilen 20%igem Oleum gelöst. Die Reaktionsmasse wird ungefähr 20 Stunden auf 40-45' C er wärmt und dann mit Eis versetzt. Die stark mineralsaure Farbstofflösung wird nun mit Natronlauge von 33'B6, zweckmässig unter äusserer Kühlung, neutralisiert, wobei sieh der gebildete Farbstoff ausscheidet. Er wird abgesiaugt 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-sulfonic acid is condensed with 4-aminophenetidyl - diethylamine and the resulting condensation product is condensed with treated with a sulfonating agent until a sulfo group occurs.
The dyestuff thus obtained dissolves in concentrated sulfuric acid with a pale blue color which does not change noticeably on addition of paraformaldehyde. It dyes wool in clear, rusty blue shades of good lightfastness and has excellent equalizing properties.
<I> Example: </I> 100 parts of 1-amino-4-bromoanthraquinone-2-sulfonic acid are dissolved in a mixture of 5200 parts of water and 1800 parts of alcohol and mixed with <B> 63 </B> parts of 4-amino- phenetidyl diethylamine, 100 parts of sodium bicarbonate and 10 parts of copper chloride were added. The reaction solution is heated to boiling for several hours and the reaction product formed is deposited by acidification. It is suctioned off and washed out well with hot water.
80 parts of the above condensation product are dissolved in a mixture of 800 parts of sulfuric acid monohydrate and 80 parts of 20% strength oleum. The reaction mass is heated to 40-45 'C for about 20 hours and then ice is added. 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 separated out. It is vacuumed off and washed with .salt water of <B> 15'B6 </B>.
