Zusatz - Patent zu No. 28753 vom 27. Februar 1884.Addition - Patent to No. 28753 of February 27, 1884.
Fatentirt im Deutschen Reiche vom 17. März 1885 ab. Längste Dauer: 26. Februar 1899.Fatentirt in the German Empire from March 17, 1885. Longest duration: February 26, 1899.
Die Tetrazoverbindungen des Tolidins, dargestellt durch alkalische Reduction von Ortho- oder Paranitrotoluol oder von einem Gemisch beider, dem technischen Nitrotoluol, können mit α- und ß-Naphtylamin und deren Mono- und Disulfosäuren schöne, theils sprit-, theils wasserlösliche Farbstoffe bilden, welche ungeheizte Baumwolle im Seifenbade intensiv gelbroth bis blauroth färben und von den entsprechenden Benzidinfarbstoffen durch ihre Nuance und gröfsere Echtheit gegen Licht und Säuren wesentlich verschieden sind. Während der von Böttiger in Lodz aus Tetrazodiphenyl mit a-Naphtionsäure erhaltene und im Handel unter dem Namen »Congo« bekannte rothe Farbstoff von den geringsten Spuren Essigsäure braun bis schwarz wird, zeigt der entsprechende Farbstoff aus Tetrazoditoiyi bei weitem nicht so grofse Empfindlichkeit gegen verdünnte Säuren und ist bedeutend lichtechter als dieser.The tetrazo compounds of tolidine, represented by the alkaline reduction of ortho- or paranitrotoluene or a mixture of both, technical grade nitrotoluene, can with α- and β-naphthylamine and their mono- and disulphonic acids are beautiful, partly gas-soluble, partly water-soluble Forms of dyes, which unheated cotton in a soap bath can be intensely yellow-red to Blue-red in color and from the corresponding benzidine dyes by their nuances and greater Fastness to light and acids are essentially different. During the von Böttiger obtained in Lodz from tetrazodiphenyl with a-naphthoic acid and sold under the Name »Congo« known red dye from the slightest traces of acetic acid to brown becomes black, the corresponding dye from Tetrazoditoiyi is nowhere near as large Sensitivity to dilute acids and is significantly more lightfast than this.
Ein noch gröfserer Unterschied zwischen den Benzidin- und Tolidinfarbstoffen ergiebt sich in Combination mit β - Naphtylaminsulfosäuren, seien dieselben durch directe Sulfirung von β - Naphtylamin oder durch Erhitzen von Sch äffe r'scher ß-Naphtolsulfosäure mit Ammoniak erhalten. In beiden Fällen bildet Tetrazodiphenyl mit denselben Farbstoffe, welche selbst in kochendem Wasser unlöslich und in der beschriebenen Form nicht auf Baumwolle zu fixiren, also technisch absolut werthlos sind. Tetrazoditoiyi dagegen bildet in Combination mit diesen Sulfosäuren Farbstoffe, welche in Wasser leicht löslich und durch ihre absolute Echtheit gegen starke Essigsäure und selbst gegen verdünnte mineralische Säuren und durch das Feuer ihrer Farbe sehr werthvoll sind.There is an even greater difference between the benzidine and tolidine dyes in Combination with β-naphthylamine sulfonic acids are said to be the same by direct sulfonation of β-naphthylamine or by heating Schäffe r'scher ß-naphthol sulfonic acid with ammonia obtain. In both cases, tetrazodiphenyl forms dyes with the same, which Insoluble even in boiling water and not in the form described on cotton to fix, that is, are technically absolutely worthless. Tetrazoditoiyi, on the other hand, forms in combination with these sulfonic acids dyes, which are easily soluble in water and by their absolute Fastness to strong acetic acid and even to dilute mineral acids and through the fire of their color are very valuable.
Man stellt diese Farbstoffe am besten in der Weise dar, dafs man wässerige Lösungen der Tetrazoditolylsalze in die wässerigen Lösungen der α- und ß-Naphtylaminsalze oder in die in Wasser fein suspendirten Mono- und Disulfosäuren des a- und β - Naphtylamins einlaufen läfst und die vorhandenen freien mineralischen Säuren durch Salze der organischen Säuren, z. B. durch essigsaures Natron, abstumpft. An Stelle der wässerigen Lösungen lassen sich auch die alkoholischen Lösungen, an Stelle der freien Säuren auch deren Salze in alkalischer Lösung verwenden.It provides these dyes in the best way is, that we aqueous solutions of Tetrazoditolylsalze in the aqueous solutions of α- and ß-Naphtylaminsalze or in that of the a- in water finely suspendirten mono- and disulfonic acids and β - enter Naphtylamins läfst and existing free mineral acids by salts of organic acids, z. B. by sodium acetate, dulls. Instead of the aqueous solutions, it is also possible to use alcoholic solutions, and instead of the free acids, their salts in alkaline solution can also be used.
Die so gebildeten spritlöslichen Farbstoffe werden durch Behandeln mit rauchender Schwefelsäure in wasserlösliche Farbstoffe übergeführt, die dann in ihren Eigenschaften grofse Äehnlichkeit mit den direct erhaltenen wasserlöslichen Farbstoffen zeigen, nur etwas stumpfer als diese sind.The thus formed fuel-soluble dyes are treated with smoking Sulfuric acid converted into water-soluble dyes, which then have great properties Show resemblance to the directly obtained water-soluble dyes, only somewhat more bluntly than these are.
Als Beispiel des genauen Verfahrens zur Darstellung dieser Farbstoffe mögen folgende dienen:As an example of the detailed method for preparing these dyes, the following may be given to serve:
I. a) ι 50 kg schwefelsaures Tolidin (Diamidoditolyl), erhalten aus technischem Nitrotoluol,I. a) ι 50 kg of sulfuric acid tolidine (diamidoditolyl), obtained from technical nitrotoluene,
werden in Wasser fein suspendirt, mit 50 kg Salzsäure von 210 B. versetzt und zu der mit Eis gekühlten Lösung 22,2 kg Natriumnitrit, in 10 1 Wasser gelöst, langsam hinzulaufen gelassen.be finely suspended, mixed in water with 50 kg of hydrochloric acid 21 0 B. and dissolved to the ice-cooled solution of 22.2 kg sodium nitrite in 10 1 of water, added slowly run.
Es bildet sich so das Tetrazoditolylchlorid.The tetrazoditolyl chloride is thus formed.
Diese Lösung setzen wir darauf zu einer wässerigen Lösung von 58 kg salzsaurem a- oder β - Naphtylamin, stumpfen die freie mineralische Säure durch Natriumacetat ab und lassen das Gemisch ca. 24 Stunden stehen. Der so erhaltene dunkelbraune bezw. hochrothe Niederschlag wird abfiltrirt und behufs Ueberführung in seine Sulfosäuren getrocknet.We then add this solution to an aqueous solution of 58 kg of hydrochloric acid or β - naphthylamine, the free mineral acid blunt by sodium acetate and let the mixture stand for about 24 hours. The dark brown respectively obtained in this way. bright red Precipitate is filtered off and dried to convert it into its sulfonic acids.
b) 50 kg des trockenen, spritlöslichen Farbstoffes werden unter Umrühren langsam in 150 kg rauchende Schwefelsäure von 20 pCt. Anhydridgehalt bei 150 C. eingetragen, die so erhaltene tiefblaue Schmelze so lange bei gewöhnlicher Temperatur stehen gelassen, bis die Sulfirung vollendet, darauf in Wasser gegossen und die ausgeschiedene Sulfosäure durch Behandeln mit Natronlauge oder Soda in ihr Natronsalz übergeführt.b) 50 kg of the dry, fuel-soluble dye are slowly stirred into 150 kg of fuming sulfuric acid of 20 pCt. Anhydride was added at 15 0 C., the deep blue melt thus obtained so long as at ordinary temperature allowed to stand until the completed Sulfirung, then poured into water and the precipitated sulfonic acid converted by treatment with sodium hydroxide or sodium carbonate in their sodium salt.
II. Das in derselben Weise wie bei La) erhaltene Tetrazoditolylchlorid wird zu 73 kg in Wasser fein suspendirte Naphtionsäure (schwerlösliche α - Naphtylaminsulfosäure) hinzugefügt, die freie mineralische Säure durch Hinzufügen von essigsaurem Natron abgestumpft und das Gemisch mehrere Tage unter häufigem Umrühren stehen gelassen.II. The tetrazoditolyl chloride obtained in the same manner as in La) is 73 kg in Finely suspended naphthoic acid (poorly soluble α-naphthylamine sulfonic acid) added to water, the free mineral acid blunted by adding acetic acid baking soda and that Let the mixture stand for several days with frequent stirring.
Es bildet sich so ein rothbrauner, schleimiger Niederschlag, der durch Erwärmen und Neutralisiren mit Natronlauge oder Soda in sein Natronsalz übergeführt wird.A red-brown, slimy precipitate is formed, which by heating and Neutralization with caustic soda or soda is converted into its sodium salt.
Beim Erkalten fällt der Farbstoff fast quantitativ als ein orangerothes Pulver aus, das, abfiltrirt, ungeheizte Baumwolle intensiv blauroth färbt.On cooling the dye precipitates almost quantitatively as an orange-red powder which, when filtered off, unheated cotton dyes intensely blue-red.
III. Einen scharlachrothen, säureechten Farbstoff, der in seiner Schönheit die oben beschriebenen Farbstoffe noch übertrifft, erhält man aus der β-Naphtylaminsulfosäure, gebildet durch Erhitzen der Schäffer'schen ß-Naphtolsulfosäure mit Ammoniak.III. A scarlet, acid-fast dye, the beauty of which is that described above Exceeding dyes is obtained from the β-naphthylamine sulfonic acid, formed by heating the Schäffer ß-naphthol sulfonic acid with ammonia.
^Nachdem man zu der wässerigen Lösung von 80 kg β - naphtylaminsulfosaures Natron überschüssige Sodalösung hinzugefügt hat, läfst man in dieselbe langsam unter Umrühren und Eiskühlung das wie bei La) erhaltene Tetrazoditolylchlorid einlaufen. Es bildet sich ein bräunlichrother Niederschlag, der sich nach ca. zwölfstündigem Stehen vollständig auflöst. Fügt man nun zu der so erhaltenen Farbstofflösung Kochsalzlösung hinzu, so fällt ein rother, schleimiger Niederschlag, der durch Erwärmen krystallinisch wird und das Natronsalz jenes oben beschriebenen Farbstoffes darstellt.^ After adding to the aqueous solution of 80 kg of β-naphthylaminesulfonate of soda has added excess soda solution, it is poured into the same slowly while stirring and Ice cooling the tetrazoditolyl chloride obtained as in La) come in. A brownish-red precipitate forms, which takes about twelve hours Standing completely dissolves. If you now add saline solution to the dye solution obtained in this way, a red, slimy precipitate, which becomes crystalline when heated, and the sodium salt that represents the dye described above.
