Verfahren zur Darstellung von Küpenfarbstoffen.Process for the preparation of vat dyes.
Zusatz zum Patent 263382.*)Addition to patent 263382. *)
Patentiert im Deutschen Reiche vom 15. Juni 1912 ab. Längste Dauer: 7. September 1926.Patented in the German Empire on June 15, 1912. Longest duration: September 7, 1926.
In weiterer Ausbildung des Verfahrens desIn the further development of the
Hauptpatents 263382 bzw. des Zusatzpatents 265195 wurde gefunden, daß man an Stelle der Metallsulfide auch Metallsulfhydrate verwenden kann.Main patent 263382 or the additional patent 265195 was found to be in place the metal sulfides can also use metal sulfhydrates.
20 Teile des Kondensationsproduktes aus Chloränil und Anilin werden mit 15 Teilen Kaliumsulfhydrat in etwa 200 Teilen Sprit mehrere Stunden gekocht, bis eine Probe des Reaktionsproduktes sich in konzentrierter Schwefelsäure nicht mehr mit violettblauer, sondern blaustichigroter Farbe löst. Der so 15 20 parts of the condensation product of chloranil and aniline are boiled with 15 parts of potassium sulfhydrate in about 200 parts of fuel for several hours until a sample of the reaction product no longer dissolves in concentrated sulfuric acid with a violet-blue, but rather bluish-red color. The so 15
erhaltene Farbstoff ist sehr ähnlich dem nach Beispiel 1 der Patentschrift 265195 dargestellten, Wolle in tief gelbbraunen Tönen färbenden Produkt. Wird die Reaktionsdauer verlängert, so kann auch bei gewöhnlicher Temperatur, z. B. bei 15 bis 20 °, mit gleichem Erfolg gearbeitet werden.The dye obtained is very similar to that shown in Example 1 of patent specification 265195, Product coloring wool in deep yellow-brown tones. If the reaction time is lengthened, it can also be done with more usual Temperature, e.g. B. at 15 to 20 °, can be worked with the same success.
