Description
Verfahren zur Darstellung eines neuen Küpenfarbstoffes. Behandelt man Benzobenzanthronkarbon- säuren, die man durch Einwirkung von sauren Kondensationsmitteln auf die 1.1'-Dinaphthyl- 8. 8'-dikarbonsäure und ihre Kernsubstitutions- produkte unter gemässigten Bedingungen er hält, mit alkalischen Kondensationsmitteln, so bilden sich noch alkalilösliche Kondensa tionsprodukte,
die wahrscheinlich durch Zu sammentreten zweier Moleküle der Ausgangs körper entstanden sind und dem Violanthron- oder Isoviolanthrontyp entsprechen. Lässt man endlich auf diese Kondensationsprodukte saure Kondensationsmittel einwirken, so erhält man in Alkalien unlösliche Verbindungen, die wert volle neue Küpenfarbstoffe sind, und die Baumwolle aus der Küpe in blauen bis grauen Tönen von hervorragender Wasch-, Chlor- und Lichtechtheit anfärben.
Vorliegendes Patent bezieht sich nun auf die Darstellung eines neuen Küpenfarbstoffes durch Behandlung der gemäss dem Verfahren des Schweiz. Patentes Nr. 126194 erhältlichen Benzobenzanthronkarbonsäure von der wahr scheinlichen Formel
EMI0001.0019
mit alkalischen Kondensationsmitteln und schliessliche Einwirkung von sauren Konden sationsmitteln auf das so erhaltene alkalilös- liche Kondensationsprodukt.
Der so erhaltene Farbstoff ist ein blau schwarzes Pulver, das in den üblichen or ganischen Lösungsmitteln unlöslich ist und sich in konzentrierter Schwefelsäure mit gelb lich oliver Farbe löst. Mit alkalischem Hydro- sulfit bildet er eine schwärzlich violett ge färbte Küpe, aus der Baumwolle in der gleichen Farbe ausgefärbt wird, die durch Verhängen oder Seifen in Grünblau übergeht.
<I>Beispiel 1:</I> In eine Schmelze von 100 Teilen Ätzkali und 60 Teilen Alkohol werden bei etwa 96 10 Teile der im schweiz. Patent Nr. 126194 beschriebenen Benzobenzanthronkarbonsäure eingetragen. Md,n hält bei dieser Temperatur einige Zeit lang. Die Lösung der fertigen Schmelze in Wasser behandelt man zunächst mit Luft oder einem andern geeigneten Oxy dationsmittel, um das als Leukoverbindung entstandene Kondensationsprodukt zu oxy dieren. Aus der erhaltenen blauen Lösung wird das Kondensationsprodukt in üblicher Weise entweder durch Ausfällen mit Säure oder durch Aussalzen isoliert.
Die neue Kar bonsäure ist in trockenem Zustand ein blaues Pulver, das schon in verdünnter Sodalösung eicht löslich ist. Die Farbe der Lösung in kalter konzentrierter Schwefelsäure ist grün und geht bei längerem Stehen oder Erwärmen in olive über. Mit Hydrosulfit und Lauge wird eine blaue Lösung mit roter Fluoreszenz erhalten.
10 Teile des obigen Produktes werden in 200 Teilen Schwefelsäure 66 Be eingetragen. Die entstandene Lösung, wird solange bei gewöhnlicher Temperatur gerührt, bis eine abgeschiedene Probe nicht mehr in Alkalien löslich ist. Die Kondensation kann durch Erwärmen rascher zu Ende geführt werden. Das Reaktionsgemisch wird in Wasser ein getragen, der ausgeschiedene Farbstoff filtriert, ausgewaschen und getrocknet. Verunreini gungen des Farbstoffes können durch gelinde Behandlung mit einer verdünnten warmen, alkalischen Hydrosulfitlösung entfernt werden.
Beispiel <I>2</I> 10 Teile Benzobenzanthronkarbonsäure und 20 Teile pulverisiertes Ätzkali werden mit 120 Teilen Pyridin etwa 6 Stunden unter Rühret) am Rückflusskühler gekocht. Nach dem Verdünnen der Schmelze mit Wasser wird das Pyridin mit Wasserdampf abge trieben und die alkalische Lösung, wie in Beispiel 1 angegeben, aufgearbeitet. Die er haltene Verbindung ist mit der nach Bei spiel 1 hergestellten Karbonsäure identisch.
Bei Verwendung anderer Lösungs- bezw. Verdünnungsmittel wie Anilin, Dimethyl- anilin, Naphtalin wird das gleiche Resultat erhalten. Ebenso lässt sich das Ätzkali durch andere alkalische Kondensationsmittel, wie Anilinnatrium, Natriumamid, Natriumalko- holat, ersetzen. Die Überführung in den Farb stoff erfolgt in gleicher Weise, wie im Bei spiel 1 beschrieben.
Process for the preparation of a new vat dye. If benzobenzanthrone carboxylic acids, which are obtained by the action of acidic condensation agents on 1,1'-dinaphthyl-8,8'-dicarboxylic acid and its core substitution products under moderate conditions, are treated with alkaline condensation products, alkali-soluble condensation products are still formed,
which were probably created by the coming together of two molecules of the starting bodies and correspond to the violanthrone or isoviolanthrone type. If acidic condensation agents are finally allowed to act on these condensation products, then one obtains compounds which are insoluble in alkalis, which are valuable new vat dyes and dye the cotton from the vat in blue to gray shades of excellent washing, chlorine and lightfastness.
The present patent now relates to the preparation of a new vat dye by treating the according to the Swiss method. Patent No. 126194 available benzobenzanthrone carboxylic acid of the probable formula
EMI0001.0019
with alkaline condensation agents and finally the action of acidic condensation agents on the alkali-soluble condensation product thus obtained.
The dye thus obtained is a blue-black powder that is insoluble in the usual organic solvents and dissolves in concentrated sulfuric acid with a yellowish olive color. With alkaline hydrosulphite it forms a blackish violet-colored vat from which cotton is dyed in the same color, which changes to green-blue through hanging or soapy.
<I> Example 1: </I> In a melt of 100 parts of caustic potash and 60 parts of alcohol, 10 parts of the in Switzerland. Benzobenzanthroncarboxylic acid described in U.S. Patent No. 126194. Md, n holds for some time at this temperature. The solution of the finished melt in water is first treated with air or another suitable oxidizing agent in order to oxidize the condensation product formed as a leuco compound. The condensation product is isolated from the blue solution obtained in the customary manner either by precipitation with acid or by salting out.
When dry, the new carbonic acid is a blue powder that is readily soluble in a dilute soda solution. The color of the solution in cold concentrated sulfuric acid is green and changes to olive when left standing or heated for a long time. A blue solution with red fluorescence is obtained with hydrosulfite and lye.
10 parts of the above product are introduced into 200 parts of sulfuric acid 66 Be. The resulting solution is stirred at normal temperature until a deposited sample is no longer soluble in alkalis. The condensation can be brought to an end more quickly by heating. The reaction mixture is poured into water, the precipitated dye is filtered, washed and dried. Impurities in the dye can be removed by gentle treatment with a dilute, warm, alkaline hydrosulfite solution.
Example <I> 2 </I> 10 parts of benzobenzanthrone carboxylic acid and 20 parts of powdered caustic potash are boiled with 120 parts of pyridine for about 6 hours with stirring on a reflux condenser. After the melt has been diluted with water, the pyridine is driven off with steam and the alkaline solution, as indicated in Example 1, is worked up. The compound he obtained is identical to the carboxylic acid produced according to Example 1.
When using other solutions or Diluents such as aniline, dimethyl aniline, naphthalene will give the same result. The caustic potash can also be replaced by other alkaline condensation agents such as aniline sodium, sodium amide, sodium alcoholate. The conversion into the dye takes place in the same way as described in game 1.
