Description

Verfahren zur Herstellung von wasserunlöslichen Monoazofarbstoffen Es wurde gefunden, daß man neue wertvolle wasserunlösliche Monoiazofarbstof£e erhält, wenn man diiazotierbe 5-Amino-i, 2, 4-th@iod)i.azole mit Azo#komponenten der Benzolreihe kuppelt, die weder phenoil,iischie Hydroxylgruppen noch SuIfonsäure- o@der Carbonsäuregruppen enthalten. Infolge ihrer großen Kupplungsenergie lassen sich .die hier ver- wendeten D.iazoverbindungen auch .mit solchen Benzol:abkömmlingen der ggekennzeichneten Art ver- einigen, die nur ein geringes Kupplungsvermögen besitzen und daher übl.icherweiise nicht zur Her- stellung von Azofarbistofen Verwendung finden. Die für d iie Herstel ung der neuen Farbstoffe- zur Verwendung kommenden Diazokompone,nten sind gemäß Verfahren der Patentschrift 842 346 er- hälttich. Die neuen Farbstoffe eignen sich z. B. zum Fär- ben von Acetablcuns:tseide, vollsynthetischen Fasern, wie Polyamidfasern, Polyurethanfasern, Polyester- fasern oder Polyacrylnitrilfasern sowie Lacken und Kunststoffen. Die mit den neuen Farbstoffen er- hältiliehen Färbungen zeichnen sich durch große Klarheit und ,gute Lichtechtheit aus. So isst der blekannte Farbstoff der Zusammen- setzung 4-Methyl-2-ami,noth@azo,l --> Di-(oxäthyl)- an@ilin dGem entsprechenden vergleichbaren er- findungsgemäß hergestellten Farbstoff in .der Klar- heit, Anisgiebigkeit und Lichtechtheit deuttich unter- legen. Aus Journal für praktische Chemie, N. F., Bd.122 [19z7], S. 298, war es bereits bekannt, was@ser- unlösl.iche Azofarb,stuffe durch Kuppeln von diazo- tierterm 2-Amino,-i, 3, 4-thiodiiazo,l oder 2-Amdno:- 5-methyl-i, 3, 4-thiodiiazol mit Phenol herzustellen. Diese Farbstoffe s:in:d in Wasser nicht, jedoch in Soda und Alkalien leicht löslich. Abgesc-hen davon, daß diese Monoazofarbstoffe unter Verwendung einer anderen Diazokomponente aufgebaut werden, sind sie für das Färben von Acetat!seiide ungeeignet, da sieunter Earbtonumschlag in Alkalien löslich sind. Beispiel i 22/1o Mol (=3,54 ä) 5-Am'ino-3-p@henyl-i, 2, 4-thio- d:iazol werden in ioo ccm göo/ai@ger Phosphorsäure. gelöst und unter starker Kühlung mit 1,4 g Natriumnitrit dnazatiert. Hierauf wird eine Lösung von 2/1o Mol i-D;i-(oxyäthyl)-am@ino-3-methylbemzol (=2,9o g) in 25 ccm 50%i;geT.Esisiigsäure zugegeben und anschließend .der geb,'ildete Farbstoff durch starrkes Verdünnen mit Wasser gefällt. Der Farb- stoff wird, isoliert, mit reichlich Weisser und etwas Soida verrührt und wie üblich Isodibrt und getrock- net. Erstellt leindunkles, b@ronzrierendes Pulver jdar, das -sich in Alkohol und Essi!ge;ster mit intensiver blaustichigroter Farbe löst. Der Farbstoff färbt Acetatlmnsts@eide und Pollyamiidfastrn in klaren blaustichig roten Tönen von guter Lichtechtheit. Zu ähnlichen Farbstoffen gelangt man, wenn man das i-D@i-(oxyäthyl)-amino-3-nn-etthylb@enzo!1 durch Dn-(o@xyäthyl)@aminobenzol, i-D@iäthylamino:-3-ace- tyl-aminobenzol oder i-N-Oxäthyd-N-rbutylamiino- 3-methy l!bernzal ersetzt. Beispiel 2 _ 2/i0 MOl (=2,3g) 5-Ami@no-3-methyl-i, 2, 4-thio- diäzol werden in 50 ccm Schw@efolsäurr@e von 4o2 Be gelöst und mit 13,8 ccm io°/0iger Natriumnitrit lösung runter starker Kühlung diazotiert. Zu der D:iazolösung gilbt man eine Lösung von 2/1o Mol (=3,67 g) i-D@iäthylQmino-3-dilorbenzol in 25 ccm Methanol, verdünnt anschließend mit .reichlich Weisser und riseliert den Parbstoff. Das Produkt läßt sich. .aus verdünntem Alkohol umdaristalli- sieren und bildet .dann schön bronvierrende Kri- stalle. Der Fairb,stoff färbt Acetartkunstseide und Polyam,i,dfiasern in feuchtenden roten Törnen. Zu ähnlichen Farbstoffen gelangt man., wienn man. das i-Diiäthyl!ain-ino-3-chlorb,enzo@ldurch .das Diäthy l- am,inoblemzod oder i-Diäithylamino-3-methylbenzol ersetzt. Be-ispiel3 2/1o Mol (=2,62g) 5-Am:ino-3-methoxy-i, 2, 4- thio@diazol werdiem :in 5o ccm Schwefelsäure von 40° Be mit 1,49 Natriumnitrit diiazotiert und mit einer methylalko!holischeen Lösung vom 2/1o Mal (=3,67g) i-Diäfhylamino-3-chlorbenzol versetzt. Der wie üblich durch Verdünnen :isolierte Farb- stoff färbt Acetatlmnstseidle in b:laustichigroten, sehr klarem Tönen. Beispiel 4 2/1o Mod (=2,309) 5-Amino-3-mlethyl-i, 2, 4-thio- diazol werden in 50 ccm Schw efel'säUre' von 40° Be mit 13,8 ccm ioo/oiger Natriumnitritlösung unter starkem Kühlung und Rühren diazo,tiert. Zu der Dizzfllösung gibt man 2/1o Mol (=2,i6 g) Methoxy- benzod. Der Farbstoff ,scheidet :sich bald £n Form von orangegellben Kr.üs-tal.len ab, die isoliert werden und sich aus,verdünntem Alkolhol umkristalltisieren lassen. Der Farbstoff färbt Aoetatkwnsts-eide in klauen gelben Tönen. Process for the preparation of water-insoluble monoazo dyes It has been found that you can get new valuable water-insoluble monoazo dyes, if to diiazotize 5-amino-i, 2, 4-th @ iod) i.azole with Azo # components of the benzene series couple that neither phenoil, iischie hydroxyl groups nor sulfonic acid o @ contain the carboxylic acid groups. As a result of her large coupling energy can. also used D.iazo compounds with such Benzene: derivatives of the type identified some who have poor coupling power and are therefore usually not used to find position of azo-carbistofen use. The for the production of the new dyestuffs for Use coming diazo components, nten are according to the method of patent specification 842 346 hold up. The new dyes are suitable for. B. for dyeing ben of acetablcuns: silk, fully synthetic fibers, such as polyamide fibers, polyurethane fibers, polyester fibers or polyacrylonitrile fibers as well as paints and Plastics. The new dyes lasting colorations are characterized by large Clarity and, good lightfastness. This is how the tin-known dye eats the compound formation of 4-methyl-2-ami, noth @ azo, l -> di- (oxethyl) - an @ ilin dGem corresponding comparable dye produced according to the invention in the clear meaning, aniseedness and lightfastness place. From Journal for Practical Chemistry, NF, Vol. 122 [19z7], p. 298, it was already known what @ ser- insoluble azo color, graded by coupling of diazo animal term 2-amino, -i, 3, 4-thiodiiazo, l or 2-amdno: - To prepare 5-methyl-i, 3, 4-thiodiiazole with phenol. These dyes s: in: d not in water, but in Soda and alkalis easily soluble. Apart from that, that using these monoazo dyes another diazo component can be built up, if they are unsuitable for dyeing acetate! as they are soluble in alkalis under the earbone envelope are. Example i 22/10 mol (= 3.54 ä) 5-amino-3-p @ henyl-1, 2, 4-thio- d: iazol are dissolved in 100 ccm of goo / ai @ ger phosphoric acid. dissolved and with strong cooling with 1.4 g Sodium nitrite dnazated. Thereupon will be a solution of 2/10 mol id; i- (oxyethyl) -am @ ino-3-methylbemzol (= 2.9o g) in 25 ccm 50% i; GeT.esisiigsäure added and then .the built, 'formed dye through rigorous dilution with water like. The color fabric is isolated, with plenty of white and something Soida mixed and, as usual, isodibbled and dried net. Creates dark, b @ ronous powder jdar, that -s itself in alcohol and vinegar with intense bluish-tinged red color dissolves. The dye stains Acetatlmnsts @ eide and Pollyamiidfastrn in clear bluish red shades of good lightfastness. Similar dyes can be found if one the iD @ i- (oxyäthyl) -amino-3-nn-etthylb @ enzo! 1 Dn- (o @ xyäthyl) @aminobenzol, iD @ iäthylamino: -3-ace- tyl-aminobenzene or iN-Oxäthyd-N-rbutylamiino- 3-methy l! Bernzal replaced. Example 2 _ 2/10 mol (= 2.3 g) 5-Ami @ no-3-methyl-i, 2, 4-thio- Diäzol are in 50 ccm Schw @ efolsäurr @ e from 4o2 Be dissolved and with 13.8 ccm 10% sodium nitrite solution down strong cooling diazotized. To the D: iazo solution is yellowed to a solution of 2/10 mol (= 3.67 g) iD @ iäthylQmino-3-dilobenzene in 25 ccm Methanol, then diluted with plenty Whiter and risels the paraffin. The product let yourself. .from diluted alcohol to be crystallized and then forms beautiful bronzing crimes stalls. The Fairb, fabric dyes acetart silk and Polyam, i, dfiasern in damp red torns. to similar dyes one arrives, one wienn. the i-diethyl! ain-ino-3-chlorine, enzo @ l through .diethy l- am, inoblemzod or i-diethylamino-3-methylbenzene replaced. Example 3 2/10 mol (= 2.62g) 5-Am: ino-3-methoxy-i, 2, 4- thio @ diazol are: in 5o ccm sulfuric acid of 40 ° Be diiazotized with 1.49 sodium nitrite and with a methyl alcoholic solution of 2/10 times (= 3.67g) i-Diäfhylamino-3-chlorobenzene added. The, as usual, by thinning: isolated color fabric colors acetate lmnstseidle in b: laustichigroten, very clear tones. Example 4 2 / 1o Mod (= 2.309) 5-Amino-3-mlethyl-i, 2, 4-thio- diazole in 50 cc sulfuric acid 'of 40 ° Be with 13.8 ccm of 100% sodium nitrite solution strong cooling and stirring diazo, tiert. To the 2/10 mol (= 2.16 g) of methoxy- benzod. The dye that separates: soon takes shape from orange-yellow crusts, which are isolated and recrystallize from dilute alcohol permit. The dye stains aoetatkowns-silk in steal yellow tones.
