Description
Zusatzpatent zum Hauptpatent Nr. 178224. Verfahren zur Herstellung eines neuen Farbstoffes. Es wurde gefunden, dass man einen neuen Farbstoff erhält, wenn man diazotiertes 2- Amino-5-nitrophenylmethylsulfon in saurem Medium mit der Phenylamino-8-oxynaph- thalin-6-sulfonsäure vereinigt. Der neue Farbstoff bildet ein dunkles Pulver, das sich in Wasser mit grünstichig-blauer Farbe löst. Es färbt Wolle aus saurem Bade in grün stichig blauen Farbtönen an.
<I>Beispiel:</I> 216 Teile 2-Amino-5-nitrophenylmethyl- sulfon werden in konzentrierter Schwefel säure mit 69 Teilen Natriumnitrit diazotiert und die Lösung in Eiswasser gegossen. In diese Diazolösung trägt man eine neutrale Lösung von 315 Teilen Phenylamino-8-oxy- naphthalin-6-sulfonsäure ein und beschleu- nigt die Reaktion durch Zugabe von Na triumacetat. Der Farbstoff wird nun abfil- triert, ausgewaschen und getrocknet.
Additional patent to main patent no. 178224. Process for the production of a new dye. It has been found that a new dye is obtained when diazotized 2-amino-5-nitrophenylmethylsulfone is combined with phenylamino-8-oxynaphthalene-6-sulfonic acid in an acidic medium. The new dye forms a dark powder that dissolves in water with a greenish-blue color. It stains wool from an acid bath in green, blue shades.
<I> Example: </I> 216 parts of 2-amino-5-nitrophenylmethylsulfone are diazotized in concentrated sulfuric acid with 69 parts of sodium nitrite and the solution is poured into ice water. A neutral solution of 315 parts of phenylamino-8-oxynaphthalene-6-sulfonic acid is introduced into this diazo solution and the reaction is accelerated by adding sodium acetate. The dye is then filtered off, washed out and dried.
