Die schwer löslichen Sulfosäuren des geschwefelten p-Toluidins, welche in der Patentschrift Nr. 47102 beschrieben worden sind, vermögen sich nach vorhergegangener Diazotirung mit Salicylsäure, ß-Naphtol-a-monosulfosäure und analogen Verbindungen auch aufserhalb der Faser zu Farbstoffen zu vereinigen, und zwar entstehen mit Salicylsäure intensiv gelb, mit. ß-Naphtol-a-monosulfosäure schön scharlochroth färbende, auf Baumwolle ohne vorheriges Beizen fixirbare Farbstoffe.The sparingly soluble sulfonic acids of sulfurized p-toluidine, which are described in the patent No. 47102 can be obtained after previous diazotization with salicylic acid, ß-naphthol-a-monosulfonic acid and to combine analogous compounds outside the fiber to form dyes, namely, with salicylic acid, intensely yellow, with. ß-Naphtol-a-monosulfonic acid beautiful dyes that stain sharp red and can be fixed on cotton without prior pickling.
Zur Darstellung eines Baumwollgelb aus genannten Sulfosäuren und Salicylsäuren verfährt man z. B. folgendermafsen:Proceeds to produce a cotton yellow from the sulphonic acids and salicylic acids mentioned one z. B. as follows:
10 kg des Natronsalzes der Thio-p-toluidinsulfosäuren (Patent Nr. 47102) werden in 500 1 Wasser gelöst, mit 30 kg concentrirter Salzsäure (spec. Gew. 1,19) versetzt und mit 3 kg Natriumnitrit in concentrirter wässeriger Lösung diazotirt. Diese Lösung läfst man in eine Mischung von 5 kg Salicylsäure und 30 kg Soda (calcinirt), gelöst in 200 1 Wasser, allmälig einfliefsen. Der nach zwölf Stunden gebildete Farbstoff wird, wie üblich, aufgearbeitet. Er bildet ein braunrothes Pulver, welches sich in Wasser mit brauner Farbe löst; die Lösung wird durch Säuren flockig hellgelb gefällt.10 kg of the sodium salt of thio-p-toluidinsulfonic acids (Patent No. 47102) are dissolved in 500 liters of water with 30 kg of concentrated hydrochloric acid (spec. wt. 1.19) are added and 3 kg of sodium nitrite are added diazotized in concentrated aqueous solution. This solution is poured into a mixture of Gradually flow in 5 kg of salicylic acid and 30 kg of soda (calcined), dissolved in 200 liters of water. Of the Dye formed after twelve hours is worked up as usual. It forms a reddish brown Powder which dissolves in water with a brown color; the solution is precipitated in a flaky light yellow color by the acids.
Die anderen erwähnten Farbstoffe erhält man, wenn man die angegebene Menge Salicylsäure durch 20 kg ß-naphtol-a- oder ß-naphtolß-monosulfosaures Natron ersetzt.The other dyes mentioned are obtained by adding the specified amount of salicylic acid with 20 kg of ß-naphtol-a- or ß-naphtolß-monosulfosaures Soda replaced.
