Zusatzpatent zum.Hauptpatent Nr. <B>196655.</B> Verfahren zur Herstellung eines Anthrachinonfarbstoffes. Es wurde gefunden, dass wertvolle Farb stoffe der Anthrachinonreihe entstehen, wenn man Chinizarin, resp. Leukochinizarin oder andere Anthrachinonderivate, welche in 1,4- Stellung leicht austauschbare Substituenten, wie z. B.
Halogen oder 0011,9 enthalten, mit Aminodiphenyläthern und ihren Romologen kondensiert und die entstehenden Farbbasen von der allgemeinen Formel
EMI0001.0016
salioniert, wodurch zwei Sulfonsäuregruppen ins Farbstoffmolekül eintreten.
Die mit den neuen Farbstoffen auf Wolle erzielten Färbungen sind echt gegen kräftiges Waschen und Walken. Sie weisen, besonders wenn sie mit Schwefelsäure gefärbt worden sind, eine gute Pottingechtheit auf. Gleich zeitig zeichnen sie sich durch erhöhte Licht- und Alkaliechtheiten aus, mit welchen Eigen- schaften sie ähnliche Farbstoffe des Handels übertreffen.
Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines neuen, sauren Anthrachinonfarbstoffes, das darin be steht, dass die in üblicher Weise aus einem Anthrachinonderivat, das in den Stellungen <B>1</B> und 4 leicht austauschbare Substituenten besitzt,- wie beispielsweise Chinizarin, Leuko- chinizarin, deren Gemisch oder 1,
4-Dichlor- antbrachinon und 2-Amino-2-methyldipheiiyl- äther hergestellte Farbbase der Formel
EMI0001.0036
mit sulfonierenden Mitteln in die Farbstoff- disulfonsäure übergeführt, diese isoliert und mit Soda neutralisiert wird. Getrocknet und gemahlen stellt der neue Farbstoff ein dunkelgrünes Pulver dar, das sich leicht in Wasser mit blaugrüner Farbe löst und auf Wolle sauer blaugrüne Fär bungen ergibt, die sich durch gute Potting-, Licht-, Alkali- und Seewasserechtheit aus zeichnen.
<I>Beispiel:</I> 200 Teile 2-Amino-2'-methyldiphenyl- äther, 40 Teile Chinizarin, <B>30</B> Teile Leuko- chinizarin und<B>30</B> Teile Borsäure werden unter Rühren so lange auf<B>150 0 C</B> erhitzt, bis die Wasserdampfentwicklung aufgehört hat und sich die anfänglich blaue Farbe der Schmelze nicht mehr weiter nach Grün ver schiebt.
Nach dem Erkalten wird die spröde Masse gepulvert, durch Aufkochen mit ver dünnter Salzsäure der unveränderte 2-Amino- 2'-methyldiphenyläther herausgelöst und zu rückgewonnen.
Die Farbbase kann durch Behandeln mit heissem Sprit weiter gereinigt werden.
Sie wird als dunkelblaues Pulver erbal ten, das sich in Chlorbenzol mit lebhafter blaugrüner und in konzentrierter Schwefel säure mit blauer Farbe löst.
Zwecks Sulfonierung werden 4 Teile Farbbase in 20 Teile konzentrierte Schwefel säure bei<B>30 0 C</B> eingetragen. Nach 12stün- digem Rühren giesst man auf Eis. Die ab geschiedene Disulfonsäure wird abgeaaugt, in warmem Wasser mit Soda alkalisch ge- löst und der Farbstoff durch wenig Salz gefällt.
Getrocknet und gemahlen stellt er ein dunkelgrünes Pulver dar, das sich leicht in Wasser mit blaugrüner Farbe löst. Auf Wolle lassen sich sauer blaugrüne, potting- echte Färbungen erzielen, die sich durch ihre Licht-, Alkali- und Seewasserechtheit aus zeichnen.
Additional patent to the main patent no. <B> 196655. </B> Process for the production of an anthraquinone dye. It has been found that valuable dyes of the anthraquinone series arise when quinizarin, respectively. Leucoquinizarin or other anthraquinone derivatives which have easily exchangeable substituents in the 1,4-position, such as. B.
Halogen or 0011.9 contain, condensed with aminodiphenyl ethers and their romologists and the resulting color bases of the general formula
EMI0001.0016
salionized, whereby two sulfonic acid groups enter the dye molecule.
The dyeings achieved on wool with the new dyes are resistant to vigorous washing and fulling. They are particularly fast to potting when they have been dyed with sulfuric acid. At the same time, they are characterized by increased light and alkali fastness properties, with which they surpass similar commercial dyes.
The subject of the present patent is a process for the production of a new, acidic anthraquinone dye, which consists in the fact that it is made from an anthraquinone derivative which has easily exchangeable substituents in the positions 1 and 4, such as for example quinizarine, leucoquinizarine, their mixture or 1,
4-dichloro-antbrachinone and 2-amino-2-methyldipheiiyl ether produced color base of the formula
EMI0001.0036
converted with sulfonating agents into the dye disulfonic acid, this is isolated and neutralized with soda. When dried and ground, the new dye is a dark green powder that dissolves easily in water with a blue-green color and produces acidic blue-green dyeings on wool, which are characterized by good potting, light, alkali and seawater fastness.
<I> Example: </I> 200 parts of 2-amino-2'-methyldiphenyl ether, 40 parts of quinizarine, <B> 30 </B> parts of leucoquinizarine and <B> 30 </B> parts of boric acid heated to <B> 150 ° C. </B> while stirring until the development of water vapor has stopped and the initially blue color of the melt no longer shifts to green.
After cooling, the brittle mass is powdered, and the unchanged 2-amino-2'-methyldiphenyl ether is dissolved out and recovered by boiling with dilute hydrochloric acid.
The color base can be cleaned further by treating it with hot fuel.
It is inherited as a dark blue powder that dissolves in chlorobenzene with a vivid blue-green color and in concentrated sulfuric acid with a blue color.
For the purpose of sulfonation, 4 parts of color base are introduced into 20 parts of concentrated sulfuric acid at 30 ° C. After stirring for 12 hours, it is poured onto ice. The separated disulfonic acid is filtered off with suction, dissolved in warm water with soda in an alkaline solution and the dye is precipitated with a little salt.
Dried and ground, it is a dark green powder that easily dissolves in water with a blue-green color. Acid blue-green, potting-real dyes can be achieved on wool, which are characterized by their fastness to light, alkali and sea water.
