Description
Verfahren zur Darstellung eines Küpenfarbstoifes. Die Überführung der 1-Chlor-naphtalin- 2-amino-3-karbonsäure in das entsprechende 9-Chlor-naphto-3-oxy-l-thiophen und den Thio- indigofarbstoff gelingt nicht, wenn man die 1-Chlor-2-diazonaphtalin-3-karbonsäure in eine Xanthogenatlösung einträgt, das erhaltene Produkt in Natronlauge löst,
mit Chloressig säure umsetzt und die erhaltene Verbindung auf dem üblichen Wege durch Ringschliessung .in das Oxythionaphten und durch Oxydation in den entsprechenden Thioindigofarbstoff überführt (vgl. Liebigs Ann. Bd. 388 S. 18/19).
Dies liegt offenbar daran, dass das Xantho- genat der 1-Chlor-2-aminonaphtalin-3-karbon- säure nicht in das Merkaptan der Formel:
EMI0001.0019
übergeht und wahrscheinlich aus dem Grunde, weil das Chlor im Naphtalinkern der Diazo- verbindung
EMI0001.0023
so reaktionsfähig ist, dass es durch die Ein wirkung der ganthogenatlösung in Mitleiden schaft gezogen wird.
Es ist nun gefunden worden, dass man einen neuen güpenfarbstoff erhält, wenn man die 1-Chlor-2-aminonaphtalin-3-karbonsäure diazotiert und die Diazoverbindung nach der bekannten Methode von Sandmayer mit Kupfer- chlorür umsetzt, wodurch man zunächst die 1.2-Dichlornaphtalin-3-karbonsäure erhält.
Diese Verbindung kondensiert man nun mehr mit Thioglykolsäure in alkalischer Lö sung, wodurch man zu der 1-Chlor-naphtalin- 2 - thioglykol - 3 - karbonsäure gelangt. Diese Verbindung wird nun weiterhin nach dem üblichen bekannten Verfahren durch Ring schliessung in das Ogythionaphten umgewan delt, das durch Oxydation den neuen Küpen- farbstoff liefert.
Der neue dichlorierte Thioindigo-Farbstoff färbt auf Baumwolle ein lebhaftes Blau und zeichnet sieh durch sehr gute Echtbeitseigen- schaften aus.
<I>Beispiel:</I> 22 Teile 1-Chlor-2-amirio-3-naphtoesäure werden in 100 Teilen Wasser und etwa 12 Tei len Natronlauge 40 B6 heiss gelöst, heiss mit einer Lösung von 7 Teilen Natriumnitrit ver setzt und abgekühlt. Der entstandene Kristall brei wird bei 0 --5 in 300 Teile verdünnter Salzsäure (1 :1) eingetragen. Die Diazolösung wird in eine Lösung von 10 Teilen Kupfer- chlorür in 300 Teilen konzentrierter Salzsäure einlaufen lassen und langsam auf dem Was serbad erwärmt.
Unter starkem Schäumen scheidet sich die hellgelb gefärbte 1. 2-Dichlor- naphtoesäure ab, die getrocknet werden kann.
20 Teile Dichloi-naphtoesäure, 30 Teile Kalilauge, 46 %ig, 10 Teile Thioglykolsäure, 8 Teile Kupferhydroxydul in Form einer 25 o/oigen Paste und 150 Teile Wasser werden im Autoklaven 15 Stunden auf 130-135 erhitzt.
Der Bombeninhalt wird mit 10 Teilen 40 %iger Natronlauge und 70 Teilen Zink staub versetzt und auf dem Wasserbad er hitzt, wobei sich das Kupfer als Metall ab scheidet. Man filtriert ab und säuert mit Mineralsäure an; die 1-Chlor-2-rraphtylthio- glykol-3-karbonsäure fällt aus. Sie wird fil triert und getrocknet. 30 Teile der so gewonnenen Verbindung werden mit 10 Teilen wasserfreiem Natrium acetat und 150 Teilen Essigsäureanhy drid 11/i Stunden am Rilckflusskühler gekocht.
Der nach dem Abdestillieren des Essigsäureanhy- drids verbleibende Rückstand wird mit 50 Teilen Natronlauge 40 B6 und 500 Teilen Wasser auf dem Wasserbad erwärmt, bis die gebildete Acetylverbindung völlig verseift ist und mit Fer#rioyankaliumlösung versetzt, bis die Oxydation zum Farbstoff vollständig ist. Der Farbstoff färbt auf Baumwolle ein leb haftes Blau von vorzüglicher Echtheit.
Process for the preparation of a vat dye. The conversion of the 1-chloro-naphthalene-2-amino-3-carboxylic acid into the corresponding 9-chloro-naphto-3-oxy-1-thiophene and the thioindigo dye does not succeed if the 1-chloro-2-diazonaphthalene is used -3-carboxylic acid enters a xanthate solution, dissolves the product obtained in sodium hydroxide solution,
reacted with chloroacetic acid and the compound obtained in the usual way by ring closure .in the oxythionaphthene and by oxidation in the corresponding thioindigo dye (cf. Liebigs Ann. Vol. 388 pp. 18/19).
This is obviously due to the fact that the xanthogenate of 1-chloro-2-aminonaphthalene-3-carbonic acid is not converted into the mercaptan of the formula:
EMI0001.0019
passes over and probably for the reason that the chlorine in the naphthalene nucleus of the diazo compound
EMI0001.0023
is so reactive that it will be affected by the action of the ganthogenate solution.
It has now been found that a new high-quality dye is obtained if the 1-chloro-2-aminonaphthalene-3-carboxylic acid is diazotized and the diazo compound is reacted with copper chlorine by the known method of Sandmayer, whereby 1,2-dichloronaphthalene is first obtained -3-carboxylic acid is obtained.
This compound is now condensed with thioglycolic acid in an alkaline solution, which leads to 1-chloro-naphthalene-2-thioglycol-3-carboxylic acid. This compound is now further converted into the ogythionaphthene by means of ring closure in accordance with the usual known process, which supplies the new vat dye by oxidation.
The new dichlorinated thioindigo dye dyes cotton a lively blue and is characterized by very good real working properties.
<I> Example: </I> 22 parts of 1-chloro-2-amirio-3-naphthoic acid are dissolved in 100 parts of water and about 12 parts of caustic soda 40 B6, hot with a solution of 7 parts of sodium nitrite and cooled . The resulting crystal slurry is added to 300 parts of dilute hydrochloric acid (1: 1) at 0-5. The diazo solution is allowed to run into a solution of 10 parts of copper chlorine in 300 parts of concentrated hydrochloric acid and slowly heated on the water bath.
The light yellow colored 1,2-dichloronaphthoic acid separates out with strong foaming and can be dried.
20 parts of dichloronaphthoic acid, 30 parts of 46% potassium hydroxide solution, 10 parts of thioglycolic acid, 8 parts of copper hydroxide in the form of a 25% paste and 150 parts of water are heated to 130-135 for 15 hours in an autoclave.
The contents of the bomb are mixed with 10 parts of 40% sodium hydroxide solution and 70 parts of zinc dust and heated on the water bath, with the copper separating out as metal. It is filtered off and acidified with mineral acid; the 1-chloro-2-rraphthylthioglycol-3-carboxylic acid precipitates. It is filtered and dried. 30 parts of the compound thus obtained are boiled in a reflux condenser with 10 parts of anhydrous sodium acetate and 150 parts of acetic anhydride for 11½ hours.
The residue remaining after the acetic anhydride has been distilled off is heated with 50 parts of sodium hydroxide solution 40 B6 and 500 parts of water on a water bath until the acetyl compound formed has completely saponified and potassium ferric solution is added until the oxidation to the dye is complete. The dye dyes cotton a vivid blue of excellent fastness.
