KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Safranine, die sich vom Monoalkyl - ο - toluidin ableiten, sind bislang noch nicht hergestellt worden, offenbar aus dem Grunde, weil man annahm, dafs diese Farbstoffe sich von den bekannten, aus leichter zugänglichen Materialien herstellbaren Safraninen nicht wesentlich unterscheiden würden. Es wurde nun die Beobachtung gemacht, dafs die Verwendung des Monoalkyl-o-toluidine an Stelle des Dialkylanilins oder Anilins etc. zu ganz überraschenden Effecten führt. Die Klarheit und das Feuer der Nuance nimmt durch den Eintritt des Alkyltoluidinrestes derart zu, dafs einzelne der zu beschreibenden Farbstoffe den Rhodaminen als ebenbürtig an die Seite zu stellen sind. Es sind dies vor allen Dingen diejenigen Producte, welche den Monoalkylo-toluidinrest zweimal enthalten.Safranine, which is different from the monoalkyl-ο-toluidine derive have not yet been produced, apparently for the reason that it was assumed that these dyes differed from the known ones and were more easily accessible Materials that can be made from saffranines would not differ significantly. It was the observation has now been made that the monoalkyl-o-toluidine was used instead of dialkylaniline or aniline etc. to be quite surprising Effecten leads. The clarity and fire of nuance increases by entering of the alkyltoluidine radical in such a way that some of the dyes to be described are the Rhodamines are to be put aside as equals. These are above all those products which contain the monoalkylo-toluidine residue twice.
Das Verfahren zur Gewinnung der neuen Producte ist das für die Darstellung von Safraninen bekannte und gebräuchliche. Es besteht darin, dafs man p-Amidomonoalkylo-toluidin mit einem primären, secundären oder tertiären aromatischen Monamin zum entsprechenden Indamin combinirt und letzteres aldann mit einem primären Amin zum Safranin zusammen oxydirt. Selbstredend läfst sich der Procefs auch in der Weise ausführen, dafs man, statt vom p- Amidomonoalkyl-o-toluidin auszugehen, p-Phenylendiamin, p-Amidodialkylanilin etc. mit dem Monoalkyl-o-toluidin vereinigt. Ferner lassen sich die beiden Operationen, die Bildung des Indamins und die Ueberführung des letzteren in das Safranin, zu einer einzigen Operation vereinigen, indem man p- Amidomonoalkyl-o-toluidin direct mit 2 Mol. einer primären Base oder mit einem Gemisch aus 1 Mol. einer primären und 1 Mol. einer secundären oder tertiären Base zusammen oxydirt.The procedure for obtaining the new products is that for the representation of Saffronines known and used. It consists in using p-amidomonoalkylo-toluidine with a primary, secondary or tertiary aromatic monamine to the corresponding Indamine and the latter then combine with a primary amine to form saffranine together oxidized. Of course, the process can also be carried out in such a way that instead of p-amidomonoalkyl-o-toluidine go out p-phenylenediamine, p-amidodialkylaniline etc. with the monoalkyl-o-toluidine united. Furthermore, the two operations, the formation of indamine and the conversion of the latter into saffranine, to combine in a single operation by one p-amidomonoalkyl-o-toluidine directly with 2 mol. A primary base or with a Mixture of 1 mol. Of a primary and 1 mol. a secondary or tertiary base is oxidized together.
18,6 Theile salzsaures Nitrosömonometbylo-toluidin, gelöst in cira 500 Theilen Wasser, werden in üblicher Weise durch Zinkstaub und Salzsäure in das entsprechende Diamin übergeführt und die neutrale Lösung mit einer Lösung von 15,8 Theilen salzsaurem Monomethyl-o-toluidin versetzt. Unter Kühlung und fortwährendem Umrühren fügt man 20 Theile Kaliumbichromat in 5procentiger .Lösung und nach vollendeter Indaminbildung eine Lösung von 14,5 Theilen salzsaurem o-Toluidin hinzu. Hierauf wird so lange erwärmt, bis die blaugrüne Farbe der Lösung in ein reines Roth übergegangen ist, worauf durch nochmaligen Zusatz von 20 Theilen Bichromat . und weiteres Erwärmen die Farbstoffbildung zu Ende geführt wird. Man fütrirt und salzt das gebildete Safranin aus. Der Farbstoff färbt tannirte Baumwolle in sehr feurigen, rothen Nuancen an, welche an die mit Rhodamin S erzielten erinnern.18.6 parts hydrochloric acid nitrosonometbylo-toluidine, dissolved in about 500 parts of water, are removed in the usual way by zinc dust and hydrochloric acid converted into the corresponding diamine and the neutral solution with a Solution of 15.8 parts hydrochloric acid monomethyl-o-toluidine offset. With cooling and constant stirring, 20 parts of potassium dichromate in 5 percent solution are added Solution and, after indamine formation is complete, a solution of 14.5 parts hydrochloric acid o-Toluidine added. This is then heated until the blue-green color of the solution has passed into a pure red, whereupon by a further addition of 20 parts of bichromate . and further heating to complete the dye formation. One feeds and salt out the saffranine that is formed. The dye stains tannin cotton very much fiery, red nuances that are reminiscent of those obtained with Rhodamine S.
Die aus 18,6 Theilen salzsaurem Nitrosomonomethyl-o-toluidin nach Beispiel 1 durch Reduction erhaltene Lösung von ρ-Amidomono-The nitrosomonomethyl-o-toluidine from 18.6 parts hydrochloric acid according to Example 1 obtained by reduction solution of ρ-amidomono-
methyl-o-toluidin"wird mit 29 Theilen salzsaurem o-Toluidin (2 Mol.) in 500 Theilen Wasser versetzt und hierauf durch Zusatz von 40 Theilen Kaliumbichromat in 5 procentiger Lösung unter Erwärmen zum Safranin oxydirt. Dasselbe färbt tannirte Baumwolle etwas weniger lebhaft und in etwas gelbstichigeren Nuancen an als der Farbstoff des Beispiels 1.methyl-o-toluidine "becomes hydrochloric acid with 29 parts o-toluidine (2 mol.) is added in 500 parts of water and then by the addition of 40 parts of potassium dichromate in a 5 per cent solution are oxidized to safranine with warming. It dyes tannin cotton somewhat less vividly and in somewhat more yellowish nuances on than the dye of Example 1.
Aehnliche Producte entstehen, wenn man in Beispiel 1 an Stelle des salzsauren Monomefhyl o-toluidins eine andere secundäre Base, wie Monomethyl- oder Monoäthylanilin,'oder eine tertiäre Base, wie Dimethylanilin, setzt. Andererseits lä'fst sich auch das in genanntem Beispiel benutzte o-Toluidin durch Anilin, o-Anisidin oder eine andere primäre Base ersetzen.Similar products arise if, in Example 1, o-toluidine is used in place of the hydrochloric acid monomethyl another secondary base, such as monomethyl or monoethyl aniline, 'or a tertiary base, such as dimethylaniline, sets. On the other hand, this can also be done in the example mentioned replace used o-toluidine with aniline, o-anisidine or another primary base.
Desgleichen läfst sich selbstredend an Stelle des salzsauren o-Toluidins in Beispiel 2 die äquivalente Menge Anilin, o-Anisidin oder ein Gemisch aus 1 Mol. einer primären und 1 Mol. einer secundären oder tertiären aromatischen Base verwenden.The same can of course be used instead of the hydrochloric acid o-toluidine in Example 2 equivalent amount of aniline, o-anisidine or a mixture of 1 mol. of a primary and 1 mol. use a secondary or tertiary aromatic base.
Wie bereits erwähnt, läfst sich die Darstellung der einen Monoalkyl-o-toluidinrest enthaltenden Safranine auch in der Weise vornehmen, dafs man statt vom ρ-Amidomonoalkyl-o-toluidin vom p-Phenylendiamin bezw. ρ-Amidomono- bezw. -dialkylanilin ausgeht und diese Basen mit 1 Mol. Monoalkyl-ο-toluidin und ι Mol. einer beliebigen primären Base zusammen oxydirt.As already mentioned, the representation of one monoalkyl-o-toluidine residue can be used containing safranines in such a way that instead of ρ-amidomonoalkyl-o-toluidine from p-phenylenediamine respectively. ρ-amidomono- or. -dialkylaniline runs out and these bases with 1 mol. Monoalkyl-ο-toluidine and ι mol. Any primary Base oxidized together.
i8Theile salzsaures ρ -Phenylendiamin werden mit 13,5 Theilen Monoäthyl-o-toluidin und 4 Theilen concentrirter Salzäure in 700 Theilen Alkohol gelöst und in der Kälte mit 20 Theilen Kaliumbichromat in concentrirter wässeriger Lösung allmälig versetzt. Nach Beendigung der Indaminbildung werden 1 5 Theile salzsaures ο-Toluidin und unter Erwärmen auf dem Wasserbade nochmals langsam 20 Theile Kaliumbichromat zugefügt. Hierauf wird noch eine Stunde lang erwärmt, der Alkohol abdestillirt und der Rückstand mit heifsem Wasser ausgezogen. Aus der Lösung wird das gebildete Safranin mit Kochsalz gefällt und in üblicher Weise durch Umkrystallisiren gereinigt. Der Farbstoff färbt etwas weniger lebhaft als der nach Beispiel 2 erhaltene. Partial hydrochloric acid ρ-phenylenediamine become with 13.5 parts of monoethyl-o-toluidine and 4 parts of concentrated hydrochloric acid dissolved in 700 parts of alcohol and mixed with it in the cold 20 parts of potassium dichromate in concentrated aqueous solution are gradually added. After completion the formation of indamine 1 5 parts hydrochloric acid ο-toluidine and with warming 20 parts of potassium dichromate were slowly added again on the water bath. This is then heated for another hour, the Alcohol is distilled off and the residue is extracted with hot water. Out of the solution the saffranine formed is precipitated with table salt and in the usual way by recrystallization cleaned. The color of the dye is somewhat less vivid than that obtained in Example 2.
Ersetzt man in Beispiel 3 die 18 Theile salzsaures ρ -Phenylendiamin durch 19,4 Theile p-Amidomonomethylanilin und die 15 Theile salzsaures ο -Toluidin durch 13 Theile salzsaures Anilin, so erhält man ein Safranin, welches tannirte Baumwolle in blaustichigeren Tönen anfärbt als der Farbstoff des Beispiels 3.If the 18 parts of hydrochloric acid are replaced in Example 3 ρ -phenylenediamine by 19.4 parts of p-amidomonomethylaniline and the 15 parts hydrochloric acid ο -toluidine by 13 parts hydrochloric acid Aniline, a saffranine is obtained, which tannic cotton in shades with a more bluish tinge colors as the dye of Example 3.
