Description

Verfahren zur Herstellung von Küpenfarbstoffen Es wurde gefunden, daß man wertvolle Küpenfarbstoffe erhält, wenn man I Mol einer Aryldicarbonsäure bzw. ihrer funktionellen Abkömmlinge mit 2 Mol eines' I Amino-5-aroylamino-8-alkoxyanthrachinons kondensiert. Die so erhaltenen Farbstoffe lassen sich im Gegensatz zu den entsprechenden Farbstoffen, bei deren Herstellung als Zweitkomponente I-Amino-5-benzoylaminoanthrachinon selbst verwendet wird, aus der heißen Küpe färben und ergeben auf pflanzlichen Fasern orange bis scharlachrote Färbungen von ausgezeichneten Echtheitseigenschaften, insbesondere einer sehr guten Lichtechtheit. Sie übertreffen hierin analoge Farbstoffe, die durch Kondensation von Aryldicarbonsäuredichloriden mit solchen Aminoanthrachinonabkömmlingen entstehen, die entweder nur eine Ar oylamino- oder nur eine Alkoxygruppe, aber nicht beide gleichzeitig enthalten (vgl. die Patentschriften 518017 und 52o oSS r. Die vorliegenden Farbstoffe stellen also eine wertvolle Bereicherung der Technik dar.Process for the production of vat dyes It has been found that valuable vat dyes are obtained if one moles of an aryldicarboxylic acid or their functional derivatives with 2 moles of an 'I amino-5-aroylamino-8-alkoxyanthraquinone condensed. The dyes obtained in this way can, in contrast to the corresponding Dyes, the second component of which is I-amino-5-benzoylaminoanthraquinone itself is used, dye from the hot vat and yield on vegetable fibers orange to scarlet dyeings with excellent fastness properties, in particular very good lightfastness. They outperform analogous dyes by Condensation of aryldicarboxylic acid dichlorides with such aminoanthraquinone derivatives arise that either only one arylamino or only one alkoxy group, but not contain both at the same time (see patents 518017 and 52o oSS r. The The dyes present are therefore a valuable addition to the technology.

Die als Ausgangsverbindungen verwendeten I - Amino - 5 -aroylamino-8-alkoxyanthrachinone lassen sich beispielsweise nach einer der in der Patentschrift 481 362 beschriebenen Arbeitsweisen herstellen.The I-amino-5-aoylamino-8-alkoxyanthraquinones used as starting compounds can, for example, according to one of those described in patent specification 481 362 Establish working methods.

s Beispiel 74,6kg I-Amino-5-benzoylamino-8-methoxyanthrachinon werden in fein verteilter Form in etwa Soo kg o-Dichlorbenzol bei etwa Ioo bis 120 bis zur völligen Lösung gerührt. Hierauf werden 2o kg Benzol--, 4-dicarbonsäuredichlorid zugegeben und das. Gemisch bei etwa Zoo- noch etwa :l bis 6 Stunden nachgerührt. Nach dem Erkalten wird das Kondensationserzeugnis abgesaugt,gewaschen und getrocknet. Es löst sich in könzentrierter Schwefelsäure mit blaustichigroter Farbe und färbt Baumwolle aus heißer rotbrauner Küpe in gelbstichigen Scharlachtönen, die ausgezeichnete Echtheitseigenschaften, insbesondere eine sehr gute Lichtechtheit, aufweisen.s Example 74.6kg of I-amino-5-benzoylamino-8-methoxyanthraquinone in finely divided form in about Soo kg of o-dichlorobenzene at about 100 to 120 to stirred to a complete solution. Then 20 kg of benzene, 4-dicarboxylic acid dichloride are added added and the mixture stirred at about zoo for about 1 to 6 hours. After cooling, it will Condensation product sucked off, washed and dried. It dissolves in concentrated sulfuric acid with a bluish tinge Color and dyes cotton from a hot reddish-brown vat in yellowish scarlet tones, the excellent fastness properties, in particular very good lightfastness, exhibit.

Werden Benzol-I, 3-dicarbonsäuredichlorid oder I-Chlorbenzol-3, 5-dicarbonsäuredichlorid mit I-Amino-5-benzoylamino-8-methoxyanthrachinon kondensiert, so erhält man Farbstoffe, die die pilanzliche Faser aus dunkelroter Küpe in scharlachroten Tönen färben. die ebenfalls neben vorzüglichen Echtheitseigenschaften eine hervorragende Lichtechtheit aufweisen.If benzene-1,3-dicarboxylic acid dichloride or I-chlorobenzene-3,5-dicarboxylic acid dichloride condensed with I-amino-5-benzoylamino-8-methoxyanthraquinone, dyes are obtained, which dye the mushroom fiber from a dark red vat in scarlet tones. the also in addition to excellent fastness properties, excellent lightfastness exhibit.
