FARBWERKE vorm. MEISTER LUCIUS & BRÜNING in HÖCHST a. M. Verfahren zur Darstellung nachchromierbarer Triphenylmethanfarbstoffe.FARBWERKE vorm. MASTER LUCIUS & BRÜNING in HÖCHST a. M. Process for the preparation of post-chromable triphenylmethane dyes.
Zusatz zum Patente 227105 vom 26. Mai 1909.Addendum to patent 227105 from May 26, 1909.
Patentiert im Deutschen Reiche vom 8. September 1909 ab. ,. Längste Dauer: 25. Mai 1924.Patented in the German Empire on September 8, 1909. ,. Longest duration: May 25, 1924.
Es wurde gefunden, daß in dem Verfahren des Patents 227105 der ρ-Chlorbenzaldehyd durch seine Substitutionsprodukte sowie durch andere p-Halogeiibenzaldehyde und deren Substitutionsprodukte ersetzt werden kann.It has been found that in the process of patent 227105 the ρ-chlorobenzaldehyde by its substitution products as well as by other p-Halogeiibenzaldehydes and their substitution products can be replaced.
Die so erhaltenen -Farbstoffe, die an Stelle des p-ständigen Halogenatoms einen Arylämiiiorest enthalten, ziehen in saurem Bade auf Wolle; durch nachträgliches Chromieren werden violette bis blaue Färbungen von großer Echtheit erhalten, die sich namentlich durch größere Alkaüechtheit vor den Färbungen der halogenhaltigen Ausgangsfarbstoffe auszeichnen.The thus obtained dyes, which in place of the halogen atom in the p position contain an arylemia residue, drag in an acidic bath on wool; by subsequent chrome plating, violet to blue colorations of of great authenticity, which is particularly evident in the greater alkali fastness to the dyeings of the halogen-containing starting dyes.
Der Farbstoff aus 4«6-Dichlor-3-toluylaldehyd und o-Kresotinsäure wird mit der fünffachen Menge Anilin 3 Stunden auf ioo° erwärmt. Die Aufarbeitung der Reaktionsmasse geschieht wie im Hauptpatent angegeben. The dye from 4 «6-dichloro-3-toluylaldehyde and o-cresotinic acid is with the five times the amount of aniline heated to 100 ° for 3 hours. The reaction mass is worked up as indicated in the main patent.
