mehr mineralsauer ist, und 12 Stunden gerührt. Der Farbstoff ist größtenteils abgeschieden ; man vervollständigt die Abscheidung durch Zugabe von Kochsalz, isoliert durch Filtration und bringt den Farbstoff mit 8 Teilen Soda in Lösung. Nach Zusatz von 7 Teilen Nitrit läßt man in der Kälte einlaufen in 40 Teile Salzsäure (20 ° Βέ) und Wasser. Nach einigen Stunden ist die Diazotierung beendet, worauf man die ganze Diazotierungsmasse in eine Lösung von 31,5 Teilen 2-Phenylamino-5 · 7-naphtolsulfosäure und 40 Teilen Soda einträgt und einige Stunden rührt. Ist die Kupplung beendet, wärmt man wie üblich an und salzt aus. Der Farbstoff färbt Baumwolle rotviolett; die Färbungen besitzen eine vorzügliche Lichtechtheit.is more mineral acid, and stirred for 12 hours. Most of the dye is deposited ; the separation is completed by adding sodium chloride, isolated by filtration, and 8 parts of the dye are added Soda in solution. After adding 7 parts of nitrite, the mixture is allowed to run in the cold into 40 parts of hydrochloric acid (20 °) and water. After a few hours, the diazotization is complete, whereupon the entire diazotization mass into a solution of 31.5 parts of 2-phenylamino-5 · 7-naphthol sulfonic acid and 40 parts Enter soda and stir for a few hours. When the clutch is finished, you warm up as usual on and salt out. The dye dyes cotton red-violet; the colors have a excellent lightfastness.
