Zu den Basen, welche durch Sulfuriren in echte Säurefarbstoffe übergeführt werden, zählen auch die in der Patentschrift No. 63026 beschriebenen Dinitromonophenyl-m-amidotetraalkyldiamidotriphenylcarbinole. Die Ueberführung derselben, in Säurefarbstoffe geschieht ganz nach dem im Haupt-Patent No. 48523 beschriebenen Verfahren, indem die Leukobase nach I sulfurirt und die Leukosulfosäure nach II oxydirt wird, oder durch Sulfuriren des entsprechenden Carbinols nach III.The bases which are converted into real acid dyes by sulfurizing are counted also those in patent specification no. 63026 described dinitromonophenyl-m-amidotetraalkyldiamidotriphenylcarbinols. The conversion of the same into acid dyes takes place entirely according to the main patent no. 48523 method described by the leuco base sulphurised according to I and the leucosulphonic acid is oxidised according to II, or by sulphurisation of the corresponding carbinols according to III.
50 kg Dinitromonophenyl-m-amidotetraäthyldiamidotriphenylmethan werden in 300 kgMonohydrat gelöst. Die entstandene Lösung wird kurze Zeit auf 50 bis 6o° erwärmt oder etwa 24 Stunden bei Zimmertemperatur sich selbst überlassen, bis die Ammoniakprobe anzeigt, dafs alle Base in Sulfosäure umgewandelt ist. Alsdann läfst man die Reactionsmasse in kaltes Wasser einlaufen.50 kg of dinitromonophenyl-m-amidotetraethyldiamidotriphenylmethane are dissolved in 300 kg monohydrate. The resulting solution is briefly heated to 50 to 60 ° or about Left to its own devices for 24 hours at room temperature until the ammonia test shows that all the base has been converted into sulphonic acid. The reaction mixture is then poured into cold water Running in water.
Die Sulfosäure scheidet sich zum grofsen Theil als gelbes Krystallpulver aus und der Rest krystallisirt beim Stehen nahezu vollständig aus. Dieselbe wird abfiltrirt, in Soda gelöst und das Natronsalz mit Kochsalzlösung ausgesalzen. Die Oxydation der Leukosulfosäure geschieht nach den Angaben des Haupt-Patentes.The sulfonic acid is for the most part precipitated as yellow crystal powder and the The remainder crystallizes out almost completely when standing. It is filtered off and dissolved in soda and salt out the sodium salt with saline. The Oxidation of Leucosulfonic Acid happens according to the information of the main patent.
Die neuen Farbstoffe lassen sich aus ihrer wässerigen Lösung aussalzen und bilden kupferfarbene, glänzende Krystallpulver. In Wasser lösen sich dieselben leicht mit grüner Farbe; sie färben die thierische Faser in saurem Bade grün, egalisiren sehr gut und sind wie die anderen Farbstoffe dieser grofsen Körperklasse durch Echtheit ausgezeichnet.The new dyes can be salted out from their aqueous solution and form copper-colored, shiny crystal powder. In water they easily dissolve with a green color; they color the animal fiber green in an acid bath, level out very well, and are like them other dyes of this large body class are distinguished by their fastness.
