Zusatz zum Patente 193438 vom 27. Januar 1907.*)Addendum to patent 193438 of January 27, 1907. *)
Patentiert im Deutschen Reiche vom 23.August 1908 ab. Längste Dauer: 26. Januar 1922.Patented in the German Empire on August 23, 1908. Longest duration: January 26, 1922.
Es wurde gefunden, daß man zu einem neuen wertvollen Tetrahalogenderivat des Indigos gelangen kann, wenn man den durch Chlorieren von Indigo z. B. gemäß Verfahren der amerikanischen Patentschrift 899863 erhältlichen Trichlorindigo. in der Wärme und unter Benutzung indifferenter Verdünnungsmittel bromiert. Der hierbei entstehende Monobromtrichlorindigo liefert beim Färben aus alkalischer Küpe reine blaue Nuancen, welche erheblich rotstichiger sind als die mittels Tetrabromindigo (Patent 193438) erzeugten Töne. Die Färbungen besitzen bei guter Wasch- und Chlorechtheit außerdem eine ganz vorzügliche Lichtechtheit, welche diejenige der bekannten Polyhalogenderivate des Indigos bedeutend übertrifft und selbst den höchsten Anforderungen genügen dürfte.It has been found that a new valuable tetrahalogen derivative of indigo can be obtained can get if one z by chlorinating indigo. B. according to the method of American patent 899863 available Trichloroindigo. in the warmth and with the use of indifferent diluents brominated. The resulting monobromo trichloroindigo provides pure blue nuances when dyeing from an alkaline vat, which are considerably more reddish than those produced by means of tetrabromoindigo (patent 193438) Sounds. The dyeings also have a very good fastness to washing and chlorine excellent lightfastness, which is that of the known polyhalogen derivatives of indigo significantly exceeds and should even meet the highest requirements.
10 Teile Trichlorindigo (dargestellt z. B. durch Chlorieren von Indigo in Nitrobenzol bei Gegenwart von Antimonpentachlorid gemäß der amerikanischen Patentschrift 899863) werden in 100 bis 120 Teilen Nitrobenzol suspendiert, 6 Teile Brom hinzugefügt und die Mischung im Ölbad am Rückflußkühler im Verlauf von ix/2 Stunden auf 220 bis 2250 (Ölbadtemperatur) erhitzt. Nach weiterem ι bis 2 stündigem Erhitzen bei dieser Temperatur läßt man erkalten, filtriert den ausgeschiedenen Farbstoff ab, wäscht mit Alkohol 35 10 parts of trichloroindigo (prepared, for example, by chlorinating indigo in nitrobenzene in the presence of antimony pentachloride according to American patent 899863) are suspended in 100 to 120 parts of nitrobenzene, 6 parts of bromine are added and the mixture is mixed in an oil bath on a reflux condenser over a period of i x / 2 hours heated to 220 to 225 0 (oil bath temperature). After further 2 hours of heating to ι at this temperature is allowed to cool, filtered from the precipitated dye, washed with alcohol 35
der Wärme mit Seine Lösung in Baumund trocknet. Der so erhaltene Monobromtrichlorindigo
bildet kupferglänzende, violettbraune Kristallenen, die sich in konzentrierter
Schwefelsäure mit rein blauer, in rauchender Schwefelsäure mit grünstichig blauer Farbe
lösen. In Anilin ist er in der Kälte kaum, ziemlich leicht dagegen in
rein bläuer Farbe löslich.
Nitrobenzol ist blauviolett gefärbt,
wolle wird aus alkalischer Küpe in reinen blauen Tönen angefärbt, die sich, wie bereits
erwähnt, außer durch gute Wasch- und Chlorechtheit durch eine vorzügliche Lichtechtheit
auszeichnen.the heat with its solution in tree and dry. The monobromo trichloroindigo obtained in this way forms shiny copper, violet-brown crystals, which dissolve in concentrated sulfuric acid with a purely blue color, in fuming sulfuric acid with a greenish blue color. In aniline it is seldom in the cold, but quite light in
pure blue color soluble.
Nitrobenzene is colored blue-violet,
Wool is dyed from an alkaline vat in pure blue tones, which, as already mentioned, are not only characterized by good fastness to washing and chlorine but also excellent lightfastness.
In vorstehendem Beispiel kann das Nitrobenzol auch durch andere indifferente Verdünnungs- bzw. Lösungsmittel ersetzt werden. Ferner kann man die Bromierung auch unter Zusatz von Halogenüberträgern vornehmen.In the above example, the nitrobenzene can also be replaced by other inert diluents or solvents are replaced. The bromination can also be carried out with the addition of halogen carriers.
