Zusatzpatent zum Hauptpatent Nr. 219657. Verfahren zur Herstellung eines Küpenfarbstoffes der Naphthalimidreihe. Gegenstand dieses Patentes ist ein Ver fahren zur Herstellung eines Küpenfarb- stoffes der Naphthalimidreihe, welches da durch gekennzeichnet ist, dass man 3-Äthoxy- naphthalimid-4-thioglykolsäure mit einem al kalischen Kondensationsmittel, z. B. mit einem Ätzalkali in Gegenwart einer flüssigen aromatischen oder heterocyelischen Base, wie z. B.
Anilin, Dimethylanilin, Pyridin oder Chinolin, in der Wärme, zweckmässig bei Temperaturen etwa zwischen<B>80'</B> C und 200' C, behandelt und die so entstehende al- kalilösliche Verbindung durch Behandeln mit einem Oxydationsmittel, z.
B. durch Be handeln der erwärmten alkalischen Lösung mit Natriumhypochlorit, Kaliumferricyanid oder Ammonpersulfat, oder durch Einwir kung von Luft auf die alkalische Lösung, oder in verdünnter Essigsäure durch Wasser stoffsuperoxyd, oder mittels Schwefelsäure, zum Küpenfarbstoff kondensiert. <I>Beispiel:</I> 5,0 Gewichtsteile 3-Äthoxy-naphthalimid- 4-thio@glykolsäure (darstellbar z.
B. durch Umsetzung von 3-Äthoxy-4-br.omnaphthal- imid mit Schwefelnatrium zum entsprechen den Mercaptan und Überführung dieser Ver bindung in die Thioglykolsäure durch Re aktion mit Monochloressigsäure, bildet aus Eisessig kristallisiert gelbe Nadeln vom Schmelzpunkt 290-292' C) werden in 100 Gewichtsteilen Chinolin erwärmt; bei 90 bis <B>100'</B> C ist vollständige Lösung eingetreten.
Es werden 5,0 Gewichtsteile Atzkalipulver eingetragen, und die Temperatur wird kurze Zeit bis annähernd zum Siedepunkt des Chi- nolins gesteigert. Das Reaktionsprodukt scheidet sich dabei als in Chinolin unlösliche, dunkelbraune Masse ab. Es wird vom Chino- lin z. B. durch Wasserdampfdestillation be freit. Die dabei erhaltene alkalische Lösung wird bei<B>50-60'</B> C mit verdünnter Natrium- hypochloritlösung versetzt, bis keine weitere Veränderung mehr erfolgt.
Die Fluoreszenz der Lösung verschwindet dabei, der Farb stoff scheidet sich in blauen Flocken aus. Er wird abgesaugt, mit heissem Wasser ge waschen und getrocknet. Er ist ein blaues Pulver, liefert eine violette Nüpe und färbt die Baumwollfaser in echten, klaren blauen Tönen.
Die Überführung in den Küpenfarbstoff kann auch ohne Isolierung des Zwischen produktes auf folgende Weise erfolgen: Die wässrige, orangebraune Lösung des Konden sationsproduktes wird essigsauer gestellt, sie nimmt dann eine rotbraune Farbe an, auf Zusatz von etwa 10 Teilen einer Wasserstoff superoxydlösung entsteht eine gelbbraune Fällung, die beim Erwärmen bis zum Sieden langsam eine grünblaue Färbung annimmt.
Wenn keine Farbvertiefung mehr erfolgt, wird abfiltriert, mit heissem Wasser ge waschen und zur Entfernung alkalilöslicher Nebenprodukte mit verdünnter heisser Na tronlauge behandelt. Nach abermaligem Waschen mit Wasser hinterbleibt dann der reine Farbstoff als blauer Rückstand.
Die Überführung des Zwischenproduktes in den Farbstoff kann ferner durch Erwär men des abgeschiedenen Zwischenproduktes bei ungefähr 90-100'C in 70-75%iger Schwefelsäure auf dem Wasserbad erfolgen. Der Farbstoff scheidet sich aus der braunen Schwefelsäurelösung in blauen Kristallen ab und kann durch Absaugen auf einem Filter stein sofort in reiner Form gewonnen werden.
Additional patent to main patent No. 219657. Process for the production of a vat dye of the naphthalimide series. The subject of this patent is a process for the production of a vat dyestuff of the naphthalimide series, which is characterized by the fact that 3-ethoxy naphthalimide-4-thioglycolic acid with an alkaline condensation agent, eg. B. with a caustic alkali in the presence of a liquid aromatic or heterocyclic base, such as. B.
Aniline, dimethylaniline, pyridine or quinoline, treated with heat, expediently at temperatures between about 80 ° C. and 200 ° C., and the alkali-soluble compound thus formed by treating with an oxidizing agent, e.g.
B. act by loading the heated alkaline solution with sodium hypochlorite, potassium ferricyanide or ammonium sulfate, or by Einwir effect of air on the alkaline solution, or in dilute acetic acid by hydrogen peroxide, or by means of sulfuric acid, condensed to the vat dye. <I> Example: </I> 5.0 parts by weight of 3-ethoxy-naphthalimide-4-thio @ glycolic acid (can be represented e.g.
B. by reacting 3-ethoxy-4-br.omnaphthalimide with sodium sulfur to correspond to the mercaptan and converting this compound into thioglycolic acid by reacting with monochloroacetic acid, forms yellow needles from glacial acetic acid with a melting point of 290-292 'C) are heated in 100 parts by weight of quinoline; at 90 to <B> 100 '</B> C, complete dissolution has occurred.
5.0 parts by weight of caustic potash powder are added and the temperature is raised for a short time to almost the boiling point of the quinoline. The reaction product separates out as a dark brown mass which is insoluble in quinoline. It is used by the quinoline z. B. be freed by steam distillation. Dilute sodium hypochlorite solution is added to the alkaline solution obtained at <B> 50-60 '</B> C until there is no further change.
The fluorescence of the solution disappears and the dye separates out in blue flakes. It is suctioned off, washed ge with hot water and dried. It is a blue powder, provides a purple nub and colors the cotton fiber in real, clear blue tones.
The conversion into the vat dye can also take place without isolation of the intermediate product in the following way: The aqueous, orange-brown solution of the condensation product is made acidic, it then takes on a red-brown color, the addition of about 10 parts of a hydrogen superoxide solution results in a yellow-brown precipitate which slowly turns a green-blue color when heated to boiling.
If the color no longer deepens, it is filtered off, washed with hot water and treated with dilute hot sodium hydroxide solution to remove alkali-soluble by-products. After repeated washing with water, the pure dye then remains as a blue residue.
The intermediate product can also be converted into the dye by heating the deposited intermediate product at about 90-100 ° C. in 70-75% strength sulfuric acid on a water bath. The dye separates out of the brown sulfuric acid solution in blue crystals and can be immediately obtained in pure form by suction on a filter stone.
